Trying out Remote Desktop to a Microsoft Azure virtual machine

I have been trying out Visual Studio LightSwitch, which has an option to deploy apps to Windows Azure.

Of course I wanted to try this,  and after a certain amount of hassle generating certificates and switching between Visual Studio LightSwitch and the Azure management portal I succeeded.

image

I doubt I would have made it without this step by step guide by Andy Kung. The article begins:

One of the many features introduced in Visual Studio LightSwitch Beta 2 is the ability to publish your app directly to Windows Azure with storage in SQL Azure. We have condensed many steps one would typically have to go through to deploy an application to the cloud manually.

Somewhere between 30 and 40 screens later he writes:

The last step shows you a summary of what you’re about to publish. FINALLY! Click Publish.

We just have to imagine how many screens there would have been if Microsoft had not condensed the “many steps”. The result is also not quite right, because it uses self-signed certificates that will present security warnings when you use the app. For a product supposedly aimed at non-developers it is all hopelessly difficult; but I guess techies are used to this kind of thing.

I was not content though. First, I wanted to use an Extra Small instance, and LightSwitch defaults to a Small instance with no obvious way to change it. I cracked that one. You switch the view in Solution Explorer to the File view, then find the file ServiceDefinition.csdef and edit the vmsize attribute:

image

It worked and I had an Extra Small instance.

I was still not satisfied though. I wanted to use Remote Desktop so I could check out the VM Azure had created for me. I could not see any easy way to do this in the LightSwitch project, so I created another Azure project and configured it for Remote Desktop access using the guide on MSDN. More certificate fun, more passwords. I then started to publish the project, but bailed out when it warned me that I was overwriting a previous deployment.

Then I copied the likely looking parts of ServiceDefinition.csdef and ServiceConfiguration.cscfg from the standard Azure project to the LightSwitch project. In ServiceDefinition.csdef that was the Imports section and the Certificates section. In ServiceConfiguration.cscfg it was all the settings starting Microsoft.WindowsAzure.Plugins.Remote…; and again the Certificates section. I think that was it.

It worked. I published the LightSwitch app, went to the Azure management portal, selected the instance, and clicked Connect.

image

What I found was a virtual Quad-Core Opteron with 767MB RAM and running Windows Server 2008 Enterprise SP2. It seems Azure does not use Server 2008 R2 yet – at least, not for Extra Small instances.

image

750MB RAM is less than I would normally consider for Server 2008 – this is Extra Small, remember – but I tried using my simple LightSwitch app and it seemed to cope OK, though memory is definitely tight.

image

This VM is actually not that small in relation to many Linux VMs out there, happily running Apache, PHP, MySQL and numerous web applications. Note that my Azure VM is not running SQL Server; SQL Azure runs on separate servers. I am not 100% sure why Azure does not use Server Core for VMs like this. It may be because server core is usually used in conjunction with GUI tools running remotely, and setting up all the permissions for this to work is a hassle.

I took a look at the Event Viewer. I have never seen a Windows event log without at least a few errors, and I was interested to see if a Microsoft-managed VM would be the first. It was not, though there are a mere 16 “Administrative events” which is pretty good, though the VM has only been running for an hour or so. There were a bunch of boot-start drivers which failed to load:

image

and this, which I would describe as a typical obscure and probably-unimportant-but-who-knows Windows error:

image

The Azure VM is not domain-joined, but is in a workgroup. It is also not activated; I presume it will become activated if I leave it running for more than 14 days.

Internet Explorer is installed but I was unable to browse the web, and attempting to ping out gave me “Request timed out”. Possibly strict firewall rules prevent this. It must be carefully balanced, since applications will need to connect out.

The DNS suffix is reddog.microsoft.com – a remnant of the Red Dog code name which was originally used for Azure.

As I understand it, the main purpose of remote desktop access is for troubleshooting, not so that you can install all sorts of extra stuff on your VM. But what if you did install all sorts of extra stuff? It would not be a good idea, since – again as I understand it – the VM could be zapped by Azure at any time, and replaced with a new one that had reverted to the original configuration. You are not meant to keep any data that matters on the VM itself; that is what the Azure storage services are for.

Hands On with Visual Studio LightSwitch – but what is it for?

Visual Studio LightSwitch, currently in public beta, is Microsoft’s most intriguing development tool for years. It is, I think, widely misunderstood, or not understood; but there is some brilliant work lurking underneath it. That does not mean it will succeed. The difficulty Microsoft is having in positioning it, together with inevitable version one limitations, may mean that it never receives the attention it deserves.

Let’s start with what Microsoft says LightSwitch is all about. Here is a slide from its Beta 2 presentation to the press:

image

Get the idea? This is development for the rest of us, "a simple tool to solve their problems” as another slide puts it.

OK, so it is an application builder, where the focus is on forms over data. That makes me think of Access and Excel, or going beyond Microsoft, FileMaker. This being 2011 though, the emphasis is not so much on single user or even networked Windows apps, but rather on rich internet clients backed by internet-hosted services. With this in mind, LightSwitch builds three-tier applications with database and server tiers hosted on Windows server and IIS, or optionally on Windows Azure, and a client built in Silverlight that runs either out of browser on Windows – in which case it gets features like export to Excel – or in-browser as a web application.

There is a significant issue with this approach. There is no mobile client. Although Windows Phone runs Silverlight, LightSwitch does not create Windows Phone applications; and the only mobile that runs Silverlight is Windows Phone.

LightSwitch apps should run on a Mac with Silverlight installed, though Microsoft never seems to mention this. It is presented as a tool for Windows. On the Mac, desktop applications will not be able to export to Excel since this is a Windows-only capability in Silverlight.

Silverlight MVP Michael Washington has figured out how to make a standard ASP.NET web application that accesses a LightSwitch back end. I think this should have been an option from the beginning.

I digress though. I decided to have a go with LightSwitch to see if I can work out how the supposed target market is likely to get on with it. The project I set myself was a an index of magazine articles; you may recognize some of the names. With LightSwitch you are insulated from the complexities of data connections and can just get on with defining data. Behind the scenes it is SQL Server. I created tables for Articles, Authors and Magazines, where magazines are composed of articles, and each article has an author.

The LightSwitch data designer is brilliant. It has common-sense data types and an easy relationship builder. I created my three tables and set the relationships.

image

Then I created a screen for entering articles. When you add a screen you have to say what kind of screen you want:

image

I chose an Editable Grid Screen for my three tables. LightSwitch is smart about including fields from related tables. So my Articles grid automatically included columns for Author and for Magazine. I did notice that the the author column only showed the firstname of the author – not good. I discovered how to fix it. Go into the Authors table definition, create a new calculated field called FullName, click Edit Method, and write some code:

partial void FullName_Compute(ref string result)
{
    // Set result to the desired field value
   result = this.Firstname + " " + this.Lastname;

}

Then you set FullName as the “Summary” field for the table.

Have we lost our non-developer developer? I don’t think so, this is easier than a formula in Excel once you work out the steps. I was interested to see the result variable in the generated code; echoes of Delphi and Object Pascal.

I did discover though that my app has a usability problem. In LightSwitch, the user interface is generated for you. Each screen becomes a Task in a menu on the left, and double-clicking opens it. The screen layout is also generated for you. My problem: when I tried entering a new article, I had to specify the Author from a drop-down list. If the author did not yet exist, I had to open an Authors editable grid, enter the new author, save it, then go back to the Articles grid to select the new author.

I set myself the task of creating a more user-friendly screen for new articles. It took me a while to figure out how, because the documentation does not seen to cover my requirement, but after some help from LightSwitch experts I arrived at a solution.

First, I created a New Data Screen based on the Article table. Then I clicked Add Data Item and selected a local property of type Author, which I called propAuthor.

image

Next, I added two groups to the screen designer. Screen designs in LightSwitch are not like any screen designs you have seen before. They are a hierarchical list of elements, with properties that affect their appearance. I added two new groups, Group Button and GroupAuthor, and set GroupAuthor to be invisible. Then I dragged fields from propAuthor into the Author group. Then I added two buttons, one called NewAuthor and one called SaveAuthor. Here is the dialog for adding a button:

image

and here is my screen design:

image

So the idea is that when I enter a new article, I can select the author from a drop down list; but if the author does not exist, I click New Author, enter the author details, and click Save. Nicer than having to navigate to a new screen.

In order to complete this I have to write some more code. Here is the code for NewAuthor:

partial void NewAuthor_Execute()
{
     // Write your code here.
     this.propAuthor = new Author();
     this.FindControl("GroupAuthor").IsVisible = true;
}

Note the use of FindControl. I am not sure if there is an easier way, but for some reason the group control does not show up as a property of the screen.

Here is the code for SaveAuthor:

partial void SaveAuthor_Execute()
{
    // Write your code here.
    this.ArticleProperty.Author = propAuthor;
    this.Save();
}

image

This works perfectly. When I click Save Author, the new author is added to the article, and both are saved. Admittedly the screen layout leaves something to be desired; when I have worked out what Weighted Row Height is all about I will try and improve it.

image

Before I finish, I must mention the LightSwitch Publish Wizard, which is clearly the result of a lot of work on Microsoft’s part. First, you choose between a desktop or web application. Next you choose an option for where the services are hosted, which can be local, or on an IIS server, or on Windows Azure.

image

Something I like very much: when you deploy, there is an option to create a new database, but to export the data you have already entered while creating the app. Thoughtful.

image

As you can see from the screens, LightSwitch handles security and access control as well as data management.

What do I think of LightSwitch after this brief exercise? Well, I am impressed by the way it abstracts difficult things. Considered as an easy to use tool for model-driven development, it is excellent.

At the same time, I found it frustrating and sometimes obscure. The local property concept is a critical one if you want to build an application that goes beyond what is generated automatically, but the documentation does not make this clear. I also have not yet found a guide or reference to writing code, which would tell me whether my use of FindControl was sensible or not.

The generated applications are functional rather than beautiful, and the screen layout designer is far from intuitive.

How is the target non-developer developer going to get on with this? I think they will retreat back to the safety of Access or FileMaker in no time. The product this reminds me of more is FoxPro, which was mainly used by professionals.

Making sense of LightSwitch

So what is LightSwitch all about? I think this is a bold effort to create a Visual Basic for Azure, an easy to use tool that would bring multi-tier, cloud-hosted development to a wide group of developers. It could even fit in with the yet-to-be-unveiled app store and Appx application model for Windows 8. But it is the Visual Basic or FoxPro type of developer which Microsoft should be targeting, not professionals in other domains who need to knock together a database app in their spare time.

There are lots of good things here, such as the visual database designer, the Publish Application wizard, and the whole model-driven approach. I suspect though that confused marketing, the Silverlight dependency, and the initial strangeness of the whole package, will combine to make it a hard sell for Microsoft. I would like to be wrong though, as a LightSwitch version 2 which generates HTML 5 instead of Silverlight could be really interesting.

Fit for business? Google updates App Engine with the Enterprise in mind

Google has updated App Engine to 1.4.3. The new version adds:

Prospective Search API for Python – this lets you register a large set of queries which are executed against a flow of data so you can create notifications or other actions whenever a match is found.

Testbed Unit Test Framework for Python – this lets you create stubs for Google services for lightweight unit tests.

Concurrent requests for Java – a single application instance can now serve multiple requests provided it is marked threadsafe. An important feature.

Java Remote API – the remote API lets you access an App Engine datastore from your local machine.

I have had the sense that Google App Engine is more attractive to start-ups and small organisations than to enterprise customers. It is interesting to see Google working on bringing the Java and Python runtimes closer to parity, as Java is more widely used for enterprise development.

Another initiative aimed at enterprise customers is App Engine for Business, currently in preview. What you get is:

An Enterprise Administration Console console for managing all apps built by your company, with access control lists.

99.9% service level agreement

Hosted SQL:

While many applications can be built on the App Engine Datastore (which uses Google’s BigTable database system), we know SQL is the industry standard for the enterprise, so we’ve got you covered. SQL database support on App Engine gives enterprise developers access to the full capabilities of a dedicated relational database, without the headache of managing it.

SSL to an URL that uses your domain, such as https://myapp.apps.example.com.

Pricing – $8 per user up to a maximum of $1000 per month. In other words, if you have more than 125 users the cost per user starts coming down; if you have 1000 users it is a bargain.

Has Google done enough to make App Engine attractive to enterprise customers? This post from a frustrated developer back in November 2010 complained about stability issues and other annoyances that do not really exist on Amazon or Microsoft Azure; the Salesforce.com platform does have some throttling limitations. But it does seem that Google is determined to address the issues and App Engine for Business looks promising.

What will it take to get developers to try Windows Azure? Microsoft improves its trial offer

Microsoft has announced an improved introductory trial for Windows Azure. You can now get:

  • 750 hours of an Extra Small Compute Instance
  • 25 hours of a Small Compute Instance
  • 500MB storage
  • 10,000 storage transactions
  • 500MB in / 500MB out data transfer
  • 1G Web Edition SQL Azure database

The offer lasts until the end of June, after which you will be charged at standard rates. The allowances are I believe per month – note that 750 hours is approximately the number of hours in a month so you can run an extra small instance continuously. This is the main change from the previous trial, which only offered 25 hours of a small compute instance.

You cannot sign up without handing over credit card details.

Further, some of these limits are not really generous. This blog, for example, would chew through those data transfer limits in no time.

Microsoft is also less generous than Amazon, which offers a year of free usage with data transfer of 15GB in and 15GB out per month. Google App Engine is free up to 1GB or persistent storage and about 5 million pages views a month.

I guess Microsoft needs to figure out whether it wants to target mainly enterprise and large-scale applications, or to offer a commodity platform to a broader market. I doubt this offer is aimed at enterprises. After all, serious commercial developers on Microsoft’s platform have MSDN subscriptions, which with premium and ultimate subscriptions already offer inclusive Azure time that is better than this: 7GB in and 14 GB out per month, for example. Startups on the BizSpark scheme also get this allowance.

This offer is for the rest of us then. It is certainly getting easier to try Azure, but is this enough to encourage experimentation? I suspect Microsoft may need to come even closer to what is offered by the competition.

Server and Tools shine in Microsoft results – so why is Bob Muglia leaving?

Microsoft released quarterly results yesterday:

Quarter ending December 31 2010 vs quarter ending December 31 2009, $millions

Segment Revenue Change Profit Change
Client (Windows + Live) 5054 -2139 3251 -2166
Server and Tools 4390 412 1776 312
Online 691 112 -543 -80
Business (Office) 5126 612 3965 1018
Entertainment and devices 3698 1317 679 314

Microsoft highlighted strong sales for Xbox (including Kinect) as well as for Office 2010, which it said in the press release is the “fastest-selling consumer version of Office in history.”

Why is Office 2010 selling better than Office 2007? My hunch is that this is a Windows 7 side-effect. New Windows, new Office. I do think Office 2010 is a slightly better product than Office 2007, but not dramatically so. SharePoint Workspace 2010, about which I mean to post when I have a moment, is a big disappointment, with a perplexing user interface and limited functionality.

Windows 7 revenue is smaller than that of a year ago, but then again the product was released in October 2009 so this is more a reflection of its successful launch than anything else.

What impressed me most is the strong performance of Server and Tools, at a time when consolidation through virtualisation and growing interest in cloud computing might be reducing demand. Even virtual machines require an OS licence though, so maybe HP should worry more than Microsoft about that aspect.

I still think they are good figures, and make Server and Tools VP Bob Muglia’s announced departure even more puzzling. Just what was his disagreement with CEO Steve Ballmer?

Server and Tools revenue includes Windows Azure, but it sounds like Microsoft’s cloud is not generating much revenue yet. Here is what CFO Peter Klein said:

Moving on to Server and Tools. For Q3 and the full year, we expect non-annuity revenue, approximately 30% of the total, to generally track with the hardware market. Multi-year licensing revenue which is about 50% of the total, and enterprise services, the remaining 20%, should grow high-single digits for the third quarter and low double-digits for the full fiscal year.

This suggests that 80% of the revenue is from licensing and that 20% is “enterprise services” – which as I understand it is the consulting and enterprise support division at Microsoft. So where is Azure?

Online services, which is Bing and advertising, announced another set of dismal results. Another part of Microsoft’s cloud, Exchange and SharePoint online, is lost somewhere in the Business segment. Overall it is hard to judge how well the company’s cloud computing products are performing, but I think it is safe to assume that revenue is tiny relative to the old Windows and Office stalwarts.

Windows Phone 7 gets a mention:

While we are encouraged by the early progress, we realize we still have a lot of work ahead of us, and we remain focused and committed to the long-term success of Windows Phone 7.

It looks like revenue here is tiny as well; and like most corporate assertions of commitment, this is a reflection of the doubts around Microsoft’s mobile strategy overall: how much of it is Windows Phone 7, and how much a future version of full Windows running on ARM system-on-a-chip packages?

Still, these are good figures overall and show how commentators such as myself tend to neglect the continuing demand for Windows and Office when obsessing about a future which we think will be dominated by cloud plus mobile.

Ten big tech trends from 2010

This was an amazing year for tech. Here are some of the things that struck me as significant.

Sun Java became Oracle Java

Oracle acquired Sun and set about imposing its authority on Java. Java is still Java, but Oracle lacks Sun’s commitment to open source and community – though even in Sun days there was tension in this area. That was nothing to the fireworks we saw in 2010, with Java Community Process members resigning, IBM switching from its commitment to the Apache Harmony project to the official OpenJDK, and the Apache foundation waging a war of words against Oracle that was impassioned but, it seems, futile.

Microsoft got cloud religion

Only up to a point, of course. This is the Windows and Office company, after all. However – and this is a little subjective – this was the year when Microsoft convinced me it is serious about Windows Azure for hosting our applications and data. In addition, it seems to me that the company is willing to upset its partners if necessary for the sake of its hosted Exchange and SharePoint – BPOS (Business Productivity Online Suite), soon to become Office 365.

This is a profound change for Microsoft, bearing in mind its business model. I spoke to a few partners when researching this article for the Register and was interested by the level of unease that was expressed.

Microsoft also announced some impressive customer wins for BPOS, especially in government, though the price the customers pay for these is never mentioned in the press releases.

Microsoft Silverlight shrank towards Windows-only

Silverlight is Microsoft’s browser plug-in which delivers multimedia and the .NET Framework to Windows and Mac; it is also the development platform for Windows Phone 7. It still works on a Mac, but in 2010 Microsoft made it clear that cross-platform Silverlight is no longer its strategy (if it ever was), and undermined the Mac version by adding Windows-specific features that interoperate with the local operating system. Silverlight is still an excellent runtime, powerful, relatively lightweight, easy to deploy, and supported by strong tools in Visual Studio 2010. If you have users who do not run Windows though, it now looks a brave choice.

The Apple iPad was a hit

I still have to pinch myself when thinking about how Microsoft now needs to catch up with Apple in tablet computing. I got my first tablet in 2003, yes seven years ago, and it ran Windows. Now despite seven years of product refinement it is obvious that Windows tablets miss the mark that Apple has hit with its first attempt – though drawing heavily on what it learnt with the equally successful iPhone. I see iPads all over the place, in business as well as elsewhere, and it seems to me that the success of a touch interface on this larger screen signifies a transition in personal computing that will have a big impact.

Google Android was a hit

Just when Apple seemed to have the future of mobile computing in its hands, Google’s Android alternative took off, benefiting from mass adoption by everyone-but-Apple among hardware manufacturers. Android is not as elegantly designed or as usable as Apple’s iOS, but it is close enough; and it is a relatively open platform that runs Adobe Flash and other apps that do not meet Apple’s approval. There are other contenders: Microsoft Windows Phone 7; RIM’s QNX-based OS in the PlayBook; HP’s Palm WebOS; Nokia Symbian and Intel/Nokia MeeGo – but how many mobile operating systems can succeed? Right now, all we can safely say is that Apple has real competition from Android.

HP fell out with Microsoft

Here is an interesting one. The year kicked off with a press release announcing that HP and Microsoft love each other to the extent of $250 million over three years – but if you looked closely, that turned out to be less than a similar deal in 2006. After that, the signs were even less friendly. HP acquired Palm in April, signalling its intent to compete with Windows Mobile rather than adopting it; and later this year HP announced that it was discontinuing its Windows Home Server range. Of course HP remains a strong partner for Windows servers, desktops and laptops; but these are obvious signs of strain.

The truth though is that these two companies need one another. I think they should kiss and make up.

eBook readers were a hit

I guess this is less developer-oriented; but 2010 was the year when electronic book publishing seemed to hit the mainstream. Like any book lover I have mixed feelings about this and its implications for bookshops. I doubt we will see books disappear to the same extent as records and CDs; but I do think that book downloads will grow rapidly over the next few years and that paper-and-ink sales will diminish. It is a fascinating tech battle too: Amazon Kindle vs Apple iPad vs the rest (Sony Reader, Barnes and Noble Nook, and others which share their EPUB format). I have a suspicion that converged devices like the iPad may win this one, but displays that are readable in sunlight have special requirements so I am not sure.

HTML 5 got real

2010 was a huge year for HTML 5 – partly because Microsoft announced its support in Internet Explorer 9, currently in beta; and partly because the continued growth of browsers such as Mozilla Firefox, and the WebKit-based Google Chrome, Apple Safari and numerous mobile browsers showed that HTML 5 would be an important platform with or without Microsoft. Yes, it is fragmented and unfinished; but more and more of HTML 5 is usable now or in the near future.

Adobe Flash survived Apple and HTML 5

2010 was the year of Steve Jobs’ notorious Thoughts on Flash as well as a big year for HTML 5, which encroaches on territory that used to require the services of a browser plug-in. Many people declared Adobe Flash dead, but the reality was different and the company had a great year. Apple’s focus on design and usability helps Adobe’s design-centric approach even while Apple’s refusal to allow Flash on its mobile computers opposes it.

Windows 7 was a hit

Huge relief in Redmond as Windows 7 sold and sold. The future belongs to mobile and cloud; but Windows is not going away soon, and version 7 is driving lots of upgrades as even XP diehards move over. I’m guessing that we will get first sight of Windows 8 in 2011. Another triumph, or another Vista?

Single sign-on from Active Directory to Windows Azure: big feature, still challenging

Microsoft has posted a white paper setting out what you need to do in order to have users who are signed on to a local Windows domain seamlessly use an Azure-hosted application, without having to sign in again.

I think this is a huge feature. Maintaining a single user directory is more secure and more robust than efforts to synchronise a local directory with a cloud-hosted directory, and this is a point of friction when it comes to adopting services such as Google Apps or Salesforce.com. Single sign-on with federated directory services takes that away. As an application developer, you can write code that looks the same as it would for a locally deployed application, but host it on Azure.

There is also a usability issue. Users hate having to sign in multiple times, and hate it even more if they have to maintain separate username/password combinations for different applications (though we all do).

The white paper explains how to use Active Directory Federation Services (ADFS) and Windows Identity Foundation (WIF, part of the .NET Framework) to achieve both single sign-on and access to user data across local network and cloud.

image

The snag? It is a complex process. The white paper has a walk-through, though to complete it you also need this guide on setting up ADFS and WIF. There are numerous steps, some of which are not obvious. Did you know that “.NET 4.0 has new behavior that, by default, will cause an error condition on a page request that contains a WS-Federation authentication token”?

Of course dealing with complexity is part of the job of a developer or system administrator. Then again, complexity also means more to remember and more to troubleshoot, and less incentive to try it out.

One of the reasons I am enthusiastic about Windows Small Business Server Essentials (codename Aurora) is that it promises to do single sign-on to the cloud in a truly user-friendly manner. According to a briefing I had from SBS technical product manager Michael Leworthy, cloud application vendors will supply “cloud integration modules,” connectors that you install into your SBS to get instant single sign-on integration.

SBS Essentials does run ADFS under the covers, but you will not need a 35-page guide to get it working, or so we are promised. I admit, I have not been able to test this feature yet, and aside from Microsoft’s BPOS/Office 365 I do not know how many online applications will support it.

Still, this is the kind of thing that will get single sign-on with Active Directory widely adopted.

Consider FaceBook Connect. Register your app with Facebook; write a few lines of JavaScript and PHP; and you can achieve the same results: single sign-on and access to user account information. Facebook knows that to get wide adoption for its identity platform it has to be easy to implement.

On Microsoft’s platform, another option is to join your Azure instance to the local domain. This is a feature of Azure Connect, currently in beta.

Are you using ADFS, with Azure or another platform? I would be interested to hear how it is going.

Google App Engine and why vendor honesty pays

I’ve just attended a Cloudstock session on Google App Engine and new Google platform technologies – an introductory talk by Google’s Christian Schalk.

App Engine has been a subject of considerable debate recently, thanks to a blog post by Carlos Ble called Goodbye App Engine:

Choosing GAE as the platform four our project is a mistake which cost I estimate in about 15000€. Considering it’s been my money, it is a "bit" painful.

Ble’s points is that App Engine has many limitations. Since Google tends not to highlight these in its marketing, Ble discovered them as he went, causing frustrations and costly workarounds. In addition, it has not proved reliable:

Once you overcome all the limitations with your complex code, you are supposed to gain scalabilty for millions of users. After all, you are hosted by Google. This is the last big lie.

Since the last update they did in september 2010, we starting facing random 500 error codes that some days got the site down 60% of the time.

Ble has now partially retracted his post.

I am rewriting this post is because Patrick Chanezon (from Google), has added a kind and respectful comment to this post. Given the huge amount of traffic this post has generated (never expected nor wanted) I don’t want to damage the GAE project which can be a great platform in the future.

He is still not exactly positive, and adds:

I also don’t want to try Azure. The more experience I gain, the less I trust platforms/frameworks which code I can’t see.

Ble’s post is honest, but many of the issues are avoidable and arguably his main error was not to research the platform more thoroughly before than diving in. He blames the platform for issues that in some cases are implementation mistakes.

Still, here at Cloudstock I was interested to see if Schalk was going to mention any of these limitations or respond to Ble’s widely-read post. The answer is no – I got the impression that anything you can do in Java or Python, you can do on App Engine, with unlimited scalability thrown in.

My view is that it pays vendors to explain the “why not” as well as the “why” of using their platform. Otherwise there is a risk of disillusionment, and disillusioned customers are hard to win back.

The cloud permeates Microsoft’s business more than we may realise

I’m in the habit of summarising Microsoft’s financial results in a simple table. Here is how it looks for the recently announced figures.

Quarter ending September 30 2010 vs quarter ending September 30 2009, $millions

Segment Revenue Change Profit Change
Client (Windows + Live) 4785 1905 3323 1840
Server and Tools 3959 409 1630 393
Online 527 40 -560 -83
Business (Office) 5126 612 3388 561
Entertainment and devices 1795 383 382 122

The Windows figures are excellent, mostly reflecting Microsoft’s success in delivering a successor to Windows XP that is good enough to drive upgrades.

I’m more impressed though with the Server and tools performance – which I assume is mostly Server – though noting that it now includes Windows Azure. Microsoft does not break out the Azure figures but said that it grew 40% over the previous quarter; not especially impressive given that Azure has not been out long and will have grown from a small base.

The Office figures, also good, include Sharepoint, Exchange and BPOS (Business Productivity Online Suite), which is to become Office 365. Microsoft reported “tripled number of business customers using cloud services.”

Online, essentially the search and advertising business, is poor as ever, though Microsoft says Bing gained market share in the USA. Entertainment and devices grew despite poor sales for Windows Mobile, caught between the decline of the old mobile OS and the launch of Windows Phone 7.

What can we conclude about the health of the company? The simple fact is that despite Apple, Google, and mis-steps in Windows, Mobile, and online, Microsoft is still a powerful money-making machine and performing well in many parts of its business. The company actually does a poor job of communicating its achievements in my experience. For example, the rather dull keynote from TechEd Berlin yesterday.

Of course Microsoft’s business is still largely dependent on an on-premise software model that many of us feel will inevitably decline. Still, my other reflection on these figures is that the cloud permeates Microsoft’s business more than a casual glance reveals.

The “Online” business is mainly Bing and advertising as far as I can tell; and despite CTO Ray Ozzie telling us back in 2005 of the importance of services financed by advertising, that business revolution has not come to pass as he imagined. I assume that Windows Live is no more successful than Online.

What is more important is that we are seeing Server and tools growing Azure and cloud-hosted virtualisation business, and Office growing hosted Exchange and SharePoint business. I’d expect both businesses to continue to grow, as Microsoft finally starts helping both itself and its customers with cloud migration.

That said, since the hosted business is not separated from the on-premise business, and since some is in the hands of partners, it is hard to judge its real significance.

Microsoft PDC big on Azure, quiet on Silverlight

I’m at Microsoft PDC in Seattle. The keynote, introduced by CEO Steve Ballmer, started with a recap of the company’s success with Windows 7 – 240 million sold, we were told, and adoption plans among 88% of businesses – and showing off Windows Phone 7 (all attendees will receive a device) and Internet Explorer 9.

IE9 guy Dean Hachamovitch demonstrated the new browser’s hardware acceleration, and made an intriguing comment. When highlighting IE9’s embrace of web standards, he noted that “accelerating only pieces of the browser holds back the web.” It sounded like a jab at plug-ins, but what about Microsoft’s own plug-in, Silverlight? A good question. You could put this together with Ballmer’s comment that “We’ve tried to make web the feel more like native applications” as evidence that Microsoft sees HTML 5 rather than Silverlight as its primary web application platform.

Then again you can argue that it just happens Microsoft had nothing to say about Silverlight, other than in the context of Windows Phone 7 development, and that its turn will come. The new Azure portal is actually built in Silverlight.

The messaging is tricky, and I found it intriguing, especially coming after the Adobe MAX conference where there were public sessions on Flash vs HTML and a focus in the day two keynote emphasising the importance of both. All of which shows that Adobe has a tricky messaging problem as well; but it is at least addressing it, whereas Microsoft so far is not.

The keynote moved on to Windows Azure, and this is where the real news was centered. Bob Muglia, president of the Server and Tools business, gave a host of announcements on the subject. Azure is getting a Virtual Machine role, which will allow you to upload server images to run on Microsoft’s cloud platform, and to create new virtual machines with full control over how they are configured. Server 2008 R2 is the only supported OS initially, but Server 2003 will follow.

Remote Desktop is also coming to Azure, which will mean instant familiarity for Windows admins and developers.

Another key announcement was Windows Azure Marketplace, where third parties will be able to sell “building block components training, services, and finished services and applications.” This includes DataMarket, the new name for the Dallas project, which is for delivering live data as a service using the odata protocol. An odata library has been added to the Windows Phone 7 SDK, making the two a natural fit.

Microsoft is also migrating Team Foundation Server (TFS) to Azure, interesting both as a case study in moving a complex application, and as a future option for development teams who would rather not wrestle with the complexities of deploying this product.

Next came Windows Azure AppFabric Access Control, which despite its boring name has huge potential. This is about federated identity – both with Active Directory and other identity services. In the example we saw, Facebook was used as an identity provider alongside Microsoft’s own Active Directory, and users got different access rights according to the login they used.

In another guide Azure AppFabric – among the most confusing Microsoft product names ever – is a platform for hosting composite workflow applications.

Java support is improving and Microsoft says that you will be able to run the Java environment of your choice from 2011.

Finally, there is a new “Extra small” option for Azure instances, aimed at developers, priced at $0.05 per compute hour. This is meant to make the platform more affordable for small developers, though if you calculate the cost over a year it still amounts to over $400; not too much perhaps, but still significant.

Attendees were left in no doubt about Microsoft’s commitment to Azure. As for Silverlight, watch this space.
