Steve Ballmer at CES: Microsoft pins mobile hopes on Windows 8

1 Comment

Microsoft CEO Steve Ballmer gave the keynote at CES in Las Vegas last night. It was a polished performance and everything worked, but was short on vision or any immediate answer to the twin forces of Apple iPad and Google Android which are squeezing out Microsoft in the mobile world – smartphones and tablets – which currently forms the centre of attention in personal computing.

That said, CES stands for Consumer Electronics Show; and Ballmer did a good job showing off how well Kinect is performing, claiming sales of 8 million already. He showed more examples of controlling Xbox through speech and gesture, and said that Kinect is also boosting sales of the console; clearly it is now taking it beyond the hardcore market of first-person shooters.

We saw some fun new Windows devices, such as Acer’s dual-screen Iconia laptop.

There was also a demonstration of the updated Microsoft Surface which now runs full Windows 7 and does not require hidden cameras, so that it can now be used in more scenarios, such as for interactive digital signage.

All well and good; but what about mobile? We got a Windows Phone 7 demo, but no sales figures, nor any mobile partners on stage; I’m guessing they are too busy promoting their new Android devices. Ballmer did say that the phone is coming on Verizon and Sprint in the first half of this year. Application availability is improving, but how will Microsoft win attention for its smartphone? My local high street is full of mobile phone shops, none of which even stock it as far as I can tell. There is a tie-in with Xbox Live which may help a little.

The problem though is that Microsoft does not seem to be wholeheartedly behind the Windows Phone 7 OS, which is based on Windows CE with a new GUI and Silverlight/XNA runtime for applications. Rather, Microsoft is signalling that full Windows is its future mobile operating system. At CES it announced Windows on ARM, the processor of choice in mobile, and during the keynote we saw the next version of Windows (though with the Windows 7 GUI) running on various ARM devices.

The power available in new System on a Chip packages like NVIDIA’s Tegra 2 leaves me in no doubt that full Windows could technically run on almost any size of device; but that does not make it the sensible choice for all form factors. Note also that while it was not mentioned at CES, NVIDIA has said that Tegra 2 is optimized for Android.

Microsoft could plausibly have released a tablet based on the Windows Phone 7 OS, which is built for touch control, this year. Instead, it will be at least 2012 before we see a Windows 8 tablet, and we are taking it on trust that this will really work nicely with touch and not need a stylus dangling at the side. By then Apple will, I presume, be releasing iPad generation 3.

Putting this in a developer context, what is Microsoft’s mobile development platform? Silverlight and XNA? The full Windows native API? Or HTML 5? Each of these is very different and it seems to me a muddled story.

NVIDIA’s first CPU, Project Denver, aims to bring ARM to desktops and servers

At CES in Las Vegas today NVIDIA’s CEO Jen-Hsun Huang announced the company’s first CPU: Project Denver. This is a partnership with ARM, to create “a full custom processor” targeting “high performance computing – servers, PCs, super-computers, cloud computing.” NVIDIA will still licence ARM processors for mobile computing.

Since ARM has in the past focused on the mobile and embedded market, and NVIDIA on GPUs, it is a departure for both companies.

Why? Huang says it is because ARM is “the new standard microprocessor architecture.” Judging by this chart, shown at the press briefing, it is hard to disagree:

image

In a few years, said Huang, “There will be more ARM processors shipped than all the x86 chips ever shipped.”

image

NVIDIA’s press release explains that the purpose of Project Denver is to extend the range of ARM systems upwards:

For several years, makers of high-end computing platforms have had no choice about instruction-set architecture.  The only option was the x86 instruction set with variable-length instructions, a small register set, and other features that interfered with modern compiler optimizations, required a larger area for instruction decoding, and substantially reduced energy efficiency.

Denver provides a choice.   System builders can now choose a high-performance processor based on a RISC instruction set with modern features such as fixed-width instructions, predication, and a large general register file.   These features enable advanced compiler techniques and simplify implementation, ultimately leading to higher performance and a more energy-efficient processor.

The other interesting aspect of Project Denver is its integration with the GPU – as you would expect from NVIDIA:

An ARM processor coupled with an NVIDIA GPU represents the computing platform of the future.  A high-performance CPU with a standard instruction set will run the serial parts of applications and provide compatibility while a highly-parallel, highly-efficient GPU will run the parallel portions of programs.

While we tend to focus most on power efficiency for mobile devices, because we notice how long our batteries last, it is equally important for larger systems. Power consumption and dealing with heat is a key issue for datacentres, while in everyday desktop computing power consumption is a significant proportion of the running cost of an IT system.

Project Denver puts a different spin on Microsoft’s Windows-on-ARM announcement today. The assumption is that Microsoft has in mind a mobile future for Windows; but if Denver takes off it could be important on desktops and servers as well.

Before getting too excited, it is worth recalling how Intel’s Itanium, cruelly dubbed the Itanic, mostly failed in the market. That was partly thanks to design problems, and partly because the industry was too deeply hooked into x86 applications. I also recall Motorola’s doomed attempts to sell Windows NT on PowerPC in the mid Nineties.

Denver could fare better, thanks to the ubiquity of ARM in the mobile world. That said, much will depend on whether a Denver-based system really does offer significant benefits over whatever Intel and/or AMD will have come up with by the time it ships. If it is less than spectacular, Denver will be a hard sell.

Windows 8 will run on ARM processors – a natural home for Silverlight?

4 Comments

Microsoft announced today at CES in Las Vegas that the next version of Windows will run on ARM as well as Intel CPUs. But why? The reason is that ARM CPUs have huge momentum in mobile computing, thanks to their low power consumption. Microsoft wants Windows to support System on a Chip (SoC) architectures such as NVIDIA’s Tegra 2, which has two ARM Cortex-A9 CPUs combined with an HD-capable graphics processor in a single package. In its press release, the company is careful not to upset established x86/x64 partners Intel and AMD too much, emphasising that Windows will run on SoC packages based on those CPUs as well.

It is an interesting announcement, but one that raises as many questions as answers. The first concerns Microsoft’s mobile strategy, with Windows now seeming to encroach on territory that you have thought belonged to its embedded operating system, Windows CE, which underlies both Windows Mobile and Windows Phone 7. With all its legacy APIs, full-blown Windows does not seem ideal for low-powered, resource-constrained mobile devices; yet the company seems set on bringing full Windows rather than something based on Windows Phone 7 to the emerging tablet market.

The second issue is that applications will need at least re-compiling, and in many cases some re-coding, in order to run on ARM CPUs. Microsoft says it will deliver Office for ARM:

Sinofsky: Microsoft Office is an important part of customers’ PC experience and ensuring it runs natively on ARM is a natural extension of our Windows commitment to SoC architectures.

Windows and Office alone is enough for a decent business device; but customers who buy Windows on ARM expecting their existing games or applications to run will be disappointed.

We have been here before. In the early days of Windows CE, devices ran a variety of processors such as MIPS or Hitachi SH3, and developers had to compile multiple binaries and create setups that installed the right one on each device. In an attempt to overcome the friction this created, Microsoft introduced the Common Executable Format (CEF) with Windows CE 3.0 in 2000. This was an intermediate language format which was translated to native code by a “translator” when it was installed onto a device.

It sounds  a bit like .NET or Java; and it was indeed a forerunner of the .NET Common Language Runtime, which appeared in 2002. However, CEF never really caught on. Although it solved deployment issues, it introduced performance problems and was troublesome to debug. Most developers preferred to stick with true native code.

Today though .NET is mature; and we also have Silverlight, a cross-platform implementation of the .NET Framework combined with multimedia player and graphics framework. If Microsoft includes .NET and Silverlight in its ARM build of Windows, that would solve some of the deployment problems, especially for business devices. Many custom applications are built for .NET; and these would in principle run without any need to recompile, since a .NET executable is intermediate code which is compiled to native code at runtime, though any code which includes “platform invoke” calls to native APIs would not work.

It is surprising therefore that neither .NET nor Silverlight is mentioned in Windows president Steve Sinofsky’s Q&A about Windows on ARM. Still, we should not read too much into that. It would be madness if Microsoft did not support its .NET technologies on this new platform, would it not?

Hardware vendors chase Apple’s iPad at CES with Android, not Windows

1 Comment

There is a chorus of disapproval on the web today as Asus announced a full-fat Windows tablet  (Eee Slate EP121)  at CES in Las Vegas, along with three other devices running Google Android – the Eee Pad MeMo, the Eee Pad Transformer, and the Eee Pad Slider.

The most detailed “review” I’ve seen for the EP121 is on the Windows Experience Blog. Core i5, 4GB RAM, 64GB SSD, capacitive screen with touch and stylus input.

Nice in its way; but no kind of game-changer since this is an echo of early Windows slates which never achieved more than niche success. Four big disadvantages:

  • Short battery life
  • High price
  • The stylus
  • and another thing: in the rush to embrace touch computing, vendors appear to have forgotten one of the best features of those early tablets: you could rest your hand on the screen while writing with the pen. If you have a combined touch/stylus device that will not work.

Microsoft fans will be hoping CEO Steve Ballmer does not make too much of the EP121 and devices like this in tonight’s keynote. If he does, it will seem the company has learned little from failures of the past.

Asus deserves respect for introducing the netbook to the world in 2007, with the original Eee PC. It ran Linux, had an SSD in place of a hard drive, battery life was good, and above all it was light and cheap. Back then the story was how Microsoft missed the mark with its 2006 Origami project – small portable PCs running Windows – only to be shown how to do it by OEMs with simple netbooks at the right price.

Asus itself is not betting on Windows for tablet success; after all, three of the four products unveiled yesterday run Android. Despite what was apparently a poor CES press conference these may work out OK, though the prices look on the high side.

There will be many more tablets announced at CES, most of them running Android. Android “Honeycomb”, which is also Android 3.0 if Asus CEO Johnny Shih had his terminology right, is the first version created with tablet support in mind.

But why the tablet rush? The answer is obvious: it is because Apple has re-invented the category with the iPad. Since the iPad has succeeded where the Tablet PC failed, as a mass-market device, intuitively you would expect vendors to study what is right about it and to copy that, rather than repeating past mistakes. I think that includes long battery life and a touch-centric user interface; keyboard or stylus is OK as an optional extra but no more than that.

Equalling Apple’s design excellence and closed-but-seamless ecosystem is not possible for most manufacturers, but thanks to Android they can come up with devices that are better in other aspects: cheaper, more powerful, or with added features such as USB ports and Adobe Flash support.

It is reasonable to expect that at least a few of the CES tablets will succeed as not-quite iPads that hit the mark, just as Smartphones like the HTC Desire and Motorola Droid series have done with respect to the iPhone.

Microsoft? Ballmer’s main advantage is that expectations are low. Even if he exceeds those expectations, the abundance of Android tablets at CES shows how badly the company misjudged and mishandled the mobile market.

The implication for developers is that if you want app ubiquity, you have to develop for Android and iOS.

Microsoft could help itself and its developers by delivering a cross-platform runtime for the .NET Framework that would run on Android. I doubt Silverlight for Android would be technically difficult for Microsoft; but sadly after PDC it looks unlikely.

Creating a Web Application for the Google Chrome Web Store

1 Comment

I noticed an old post here getting a lot of hits: My first Google Chrome Web Application. Unfortunately it was based on an early version of Chrome’s app format. Here is an update.

My web application in this example is this blog. I created a manifest in Notepad:

image

Next, using my artistic skills, I made an icon of the required size: 128×128. I used .png format.

Then I put the manifest and the icon into a folder called itwriting-app. I tested it by using Chrome’s Tools – Extensions – Load unpacked extension. It worked fine.

image

Next I compressed  the folder to a zip file. I just right-clicked in Windows and chose Send to – Compressed (zipped) folder.

Then I logged into the Developer Dashboard at the Chrome Web Store (I had to pay $5.00) and uploaded the app:

image

Next, I had to complete some metadata. I chose a couple of categories, uploaded the icon as the image for the app, and uploaded a screenshot of a sample article. Clicked Publish Changes and it was done.

image

If you click Install, you get an icon in the Chrome Apps list, which appears when you open a new tab.

image

Of course it is just a link to a web site. Why is this interesting?

A few reasons. One is that it is easy to get started, which promotes usage.

Next, you can charge for your app. Once the user has paid, you use the Licensing API to check whether the user has paid, or is a trial user, or has not paid. This also depends on the user’s Google ID, promoting Google’s identity system as well as its payment system. Users get single sign-on if they are already logged into Google. Developers do not have to worry about storing passwords, which can be an embarrassment.

Web Apps are also interesting if you request additional permissions. There are three at the moment: geolocation, notifications, and unlimited storage. These give additional capabilities to your app. You can also enable autoupdating.

Finally, Google wants us to accept that web applications are apps too, blurring the boundaries between desktop, mobile device, and web.

Ten big tech trends from 2010

8 Comments

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?

Microsoft Outlook 2010 annoyance: tasks do not show in contact activities

1 Comment

I discovered an Outlook 2010 annoyance over this long weekend. A user I’m in touch with uses Outlook 2007 as a simple CRM system. He creates tasks that are linked to contacts, using the Contacts button at the bottom of the New Task window, things like “Call John” with some notes. If he then looks at the Outlook contact record for John, he clicks the Activities tab and sees all the tasks linked to that contact listed.

Trouble is, he upgraded to Outlook 2010 recently and the feature no longer works. The Contacts button is not in the New Task window by default, but you can get it back by selecting Show contacts linked to the current item in File – Options – Contacts. Even if you do though, the Activities list in a Contact window is broken and the tasks do not appear.

It turns out that this is a bug, possibly caught in the crossfire as Microsoft develops the Outlook Social Connector, which has its own Activities record.

Bugs are unsurprising in a product as complex and multi-faceted as Outlook; but Microsoft could do much better in its communication. This thread on “Microsoft Answers” lacks any official response; we do not even know if it is fixed in the Office 2010 SP1, now in private beta, or whether the feature has been removed and it is just the user interface that needs cleaning up.

While it is unimportant to most of us, clearly if you do use Outlook as a simple CRM system it is crucial. In fact, I recall when contact linking was introduced in Outlook it was touted as a major new feature.

Some users have resorted to re-installing Outlook 2007, which turns out to be rather awkward thanks to the interdependence between Outlook and Word, though it can be made to work.

Incidentally, I was interested to note that Microsoft performed a u-turn with regard to the availability of Business Contact Manager (BCM), an Outlook add-in and companion product. This used to be installed by default with Office Small Business edition, and was something that I used to uncheck or uninstall as I never used it and it could cause problems. Nevertheless, some people did use it, and were upset to find it missing from Outlook 2010 Home and Business. The updated Business Contact Manager was only available by download if you had a volume license for Office.

This was a silly decision, since Business Contact Manager targets very small businesses (including one-person businesses) who are least likely to have a volume license. Microsoft therefore changed its mind:

After careful consideration, we decided to simplify the Office 2010 lineup by including Outlook with BCM, a business product, only in volume licensing. We understand it is not ideal for every user. When we made this decision, we underestimated the importance of BCM to our small business customers and those who purchased previous versions of Office in retail stores or pre-installed on PCs. Worse yet, we left many of our customers, who didn’t want to buy through volume licensing, stranded with their data locked in previous versions of Office.

Since September, you can download BCM if you have any licensed copy of Outlook 2010.

Remote access to files in Microsoft Small Business Server 2011

Among the most interesting features in the new Small Business Server 2011 standard edition – I suspect it is in the Essentials version as well – is the ability to access shared folders remotely via a web application.

This is actually a feature borrowed from Windows Home Server, which also exposes shared folders in its remote access web application.

Note this is different from SharePoint, which is also available in SBS. SharePoint stores files in a SQL Server content database and publishes them in document libraries. Shared Folders by contrast are simple file shares. Although they lack the rich features of SharePoint, such as discussions, or check in and check out, they are faster and more convenient when all you want to do is to share files. Another benefit is that on the local network you can access shared folders directly with Windows Explorer. This can also be done with SharePoint, but under the covers it uses WebDAV – web distributed authoring and versioning – which is slower and can be tricky to get working, especially on Windows XP. SharePoint is also less suitable for files of types that it does not recognise, whereas a shared folder will accept anything you care to put into it.

While these may seem subtle distinctions, in practice they are not, and the matter of SharePoint versus shared folders is one that some businesses struggle with.

Now that you can publish shared folders through the Remote Web Access web site, this issue will be less pressing, since remote access without the need for VPN (virtual private network) is often the key reason for moving files into SharePoint.

The Remote Web Access site is not itself a SharePoint site; it is an ASP.NET application that you can find in C:\Program Files\Windows Small Business Server\Bin\WebApp\RemoteAccess. I noticed two ASP.NET user controls, one called filesgadget.ascx and one called richupload.ascx.

If you browse to this site, you can access folders and files in the SBS Shares to which you have access, controlled by NTFS permissions. The file sharing application will pick up any shared folders on the server. When you open a folder, the files are listed in the browser with options to upload, download, delete, rename, copy, cut or paste.

image

If you choose Upload, you can add documents by dragging them into the browser.

image

I also tried the site in Google Chrome. It worked, though not the drag-and-drop file upload. You can still upload files using a standard file chooser.

This looks to me like a great and overdue feature for Small Business Server. The only snag I can foresee is that some users may still find the SharePoint vs Shared Folder choice confusing and wonder why documents in the “Internal web site” are presented differently and with more features than those in shared folders. It may still be difficult to decide which to use; but at least the choice will no longer be driven solely by whether remote access via the browser is required.

Microsoft’s muddled licensing for Office Web Apps

1 Comment

I’ve been reviewing Microsoft’s Small Business Server 2011 – mainly the standard edition as that is the one that is finished. The more interesting cloud-oriented Essentials version is not coming until sometime next year.

In its marketing [pdf] for SBS 2011 Microsoft says:

Get things done from virtually wherever and whenever. With Office Web Apps (included in SharePoint Foundation 2010), users can view, create, and edit documents anyplace with an Internet connection.

This appears to be only a half-truth. You can install Office Web Apps into SharePoint Foundation 2010, but it is not included in a default install of SBS 2011 Standard, and as far as I can tell the setup for it is not on the DVD. If you try to download it, you will find it is only available through the Volume Licensing Service Center, and that you require a volume license for Microsoft Office to get it. You can also get it through TechNet, but this is for evaluation only.

The Office Web Apps site states:

Business customers licensed for Microsoft Office 2010 through a Volume Licensing program can run Office Web Apps on-premises on a server running Microsoft SharePoint Foundation 2010 or Microsoft SharePoint Server 2010.

and it also appears that each user requires a volume license for desktop Microsoft Office in order to use it. In other words, the Client Access License for Office Web Apps is a volume license for Office. You cannot purchase a volume license for 5 users, and then have everyone in your 50-person organisation use it.

This approach to licensing makes no sense. In fact, I’m not sure it is even internally consistent. Part of the web app concept is that you could, if need be, walk up to a PC in an internet cafe, log in to SharePoint, and make a quick edit to a Word document. You are not going to ask the management “is this machine correctly licensed for Office Web Apps?”

What if you are using Linux, or an Apple iPad (it almost works), or a RIM PlayBook, or some other device on which Office cannot be installed? These are scenarios where Office Web Apps is particularly useful; Microsoft cannot expect users to buy a license for desktop Office for machines which cannot run it.

Note Office Web Apps applications are severely cut-down in comparison to the desktop editions. It is not even close to the same thing. Further, Microsoft lets anyone in the world use Office Web Apps for free – provided it is on SkyDrive and not on a locally installed SharePoint.

Microsoft is also happy to give users of Office 365, the forthcoming hosted version of server apps including SharePoint, access to Office Web Apps:

Work from virtually any place and any device with the Office Web Apps

I’m guessing that somewhere in Microsoft the powerful Office group is insisting that Office Web Apps is a feature of the desktop product. Anyone else can see that it is not; it is a feature of SharePoint. Excluding it from SBS 2011 by default does nothing except to complicate matters for admins – and it is a fiddly install – thus reducing the appeal of the product.

Incidentally, I see nothing unreasonable about Microsoft charging for an on-premise install of Office Web Apps. But it should be licensed as a web application, not as a desktop application.

For more on this see Sharon Richardson’s post and Susan Bradley’s complaint.

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.
