In which I ask Marc Benioff, CEO Salesforce.com, if his platform is a lock-in

1 Comment

Moving from Microsoft’s PDC last week to Dreamforce (the Salesforce.com conference) this week has been an interesting experience. Microsoft is the giant still trying to come to terms with the new world of the Internet; Salesforce.com is the young upstart convinced that it has the future computing platform in its grasp. Salesforce.com is a much smaller company – revenue of just over $1 billion versus Microsoft’s $60 billion – though oddly Dreamforce is a larger conference, with nearly 10,000 attending, compared to 6,500 at PDC (numbers very approximate). Being small means greater opportunity for growth, and Salesforce.com reported 49% year on year  revenue growth in the last quarter for which figures are available [PDF], ended July 2008.

As for the actual conference, Monday was great, with an upbeat keynote and a fascinating press Q&A with CEO Marc Benioff; Tuesday failed to sustain the momentum with a disappointing keynote (people were leaving in droves as Michael Dell attempted to pitch storage servers to this on-demand crowd), and today is wind-down day.

The press Q&A covered most of the interesting questions about this company. Is it a lock-in? Will it move beyond CRM to a total cloud platform? Will it be bought by Oracle? How is the Salesforce.com platform (called Force.com) different from Microsoft’s Azure? Benioff has a great talent for sound bytes, and made endless digs at Microsoft and its new platform which he called “Azoon”. Microsoft developers are in a black room, he said, but walking out into the bright light of cloud computing – by which he means not Azure, but his stuff, naturally.

I got to ask the lock-in question. Benioff had already observed that making the platform programmable increased his hold on this customers. “It’s exactly the same thing that happened when Oracle moved from version 5 to version 6 with PL/SQL,” he said. “The database became programmable. Customers became customers for life.” Incidentally, Benioff talks a lot about Oracle, which is the database on which Salesforce.com itself runs, and refers to Larry Ellison as his mentor. I asked whether he was now asking his customers to repeat the mistakes of the past, when they locked themselves to Oracle or Microsoft or IBM, and I am going to quote his answer nearly in full:

It’s not a question of repeating the past, it’s just an aspect of our industry that it’s important for vendors to offer customers solutions that give them the ability to fully integrate with the platform. It benefits the customer and it benefits the vendor, and every major vendor has done it. That’s really the power.

I think that it’s true whether you’re writing with Google today and you’re building on the Google AdWords and AppEngine, you have to make the choice as the developer, what’s the right thing? Portability of code is just not something that we have ever got to in our industry. As a developer you want to make the right choice … but the reality is that the customers who are doing deep integration with us, those are customers who are going to be with us for a long time and we’re a strategic solution to them.

It’s not a commodity product. It never has been. If you think of it as a commodity product it’s a mistake … I’m completely honest and open about it, which is you’re making a strategic relationship decision, and you need to look at your vendor deeply, and choose what is the right thing for you. When customers bought Sybase SQL and they wrote Transact SQL, or they bought Oracle and wrote PL/SQL, or they’re writing in Visual Studio, well Visual Studio does not port over to HTML. You’re making a strategic decision …I think that’s important, that you research everything, evaluate everything … you do as a vendor end up with a very loyal customer base over time.

Are you familiar with the iPhone? [sure] So iPhone has a development environment that’s called Cocoa. So you have all these apps now on AppStore, which is a name that we used to have and we’ve given it to them, so when you write on AppStore, when you write on Cocoa, guess what, those apps are in Cocoa. And there’s nothing wrong with that.

I followed up by asking whether Sun’s Java experiment, including the idea of code portability between vendors, was an impossible dream.

If you’re writing in Java, you’re betting on Java. It’s a totally reasonable decision. You make that choice. It’s not portable away from Java, that I know of. I just think it’s an aspect of our industry. You should not avoid it, and vendors should not say something like, oh, we’re gonna offer some level of portability, just be honest about what our strategies are. When you’re writing on SQL Server, when you’re writing on Visual Studio, when you’re writing on Oracle, when you’re writing on DB2, when you’re writing on Force.com, you’re gonna be writing natively to a platform, and then the more open that platform is, the more connections there are to that platform, the more powerful that is for you. But you are making a platform decision, and our job is to make sure you choose our platform and not another platform, because once they have chosen another platform, getting them off it is usually impossible.

I give him credit: he could not be more clear. Even so, if you follow his reasoning, developers have an impossible decision at this point of inflexion in the industry. It is all very well researching Salesforce.com, or other vendors, but we cannot know the future. For example, Salesforce.com may become Oracle (an outcome that analysts I spoke to here see as very plausible), in which case you researched the wrong company.

On balance I doubt that the Force.com platform will go away, but its future cost and evolution is all a matter for speculation. That said, I do think it is an interesting platform and will be posting again about it; I’ve also made some comments on Twitter which you can find on my page there.

Salesforce.com linking with Facebook, Amazon

I’m at the Dreamforce conference in San Francisco, where Marc Benioff, CEO of Salesforce.com, and co-founder Parker Harris, are presenting new features in the force.com platform.

The first is a built-in ability to publish your Force.com data as a public web site. The service is currently in “developer preview” and set for full release in 2009. Even in preview, it’s priced per page view on your site. For example, if you have the low-end Group Edition, you get 50,000 page views free; but if you exceed that limit, you pay $1000 per month for up to 1,000,000 further page views. It would be unfortunate if you had 50,001 page views one month.

The second announcement relates to Facebook integration. This is a set of tools and services that lets you use Facebook APIs within a Force.com application, and create Facebook applications that use force.com data. Sheryl Sandberg, Facebook COO, says this is “Enterprise meets social”. The problem: Facebook is consumer-focused, more play than work. Sandberg says this deal will launch Facebook into the Enterprise. This will be an interesting one to watch.

Third, there are new tools linking Force.com with Amazon’s S3 and EC2. Tools for S3 wrap Amazon’s API with Apex code (Apex is the language of Force.com) so you can easily add unlimited storage to your Force.com application. Tools for EC2 delivers pre-built Amazon Virtual Machines (AMIs) that have libraries for accessing Force.com data and applications. The first AMI is for PHP, and simplifies the business of building a PHP application that extends a Force.com solution.

Interesting that Salesforce.com is providing two new ways to build public web sites that link to Force.com – one on its own platform, the other using PHP and in future Ruby, Java (I presume) etc.

It’s worth noting that you could already do this by using the SOAP API for Force.com, and there are already wrappers for languages including PHP. This is mainly about simplifying what you could already do.

UK job stats show Java decline

2 Comments

Long-time readers of this blog may recall that I occasionally track IT job vacancies at Jobserve. There may be better sites to track; but it carries a lot of vacancies, and I need to be consistent. I started in early 2002 with the goal of seeing how much adoption Microsoft was winning for its .NET technology. In March 2002, there were 153 vacancies which mentioned C#, versus 2092 for Java.

Since then, C# has grown steadily. Today it overtook Java for the first time (in my random and infrequent visits). There are 2206 C# vacancies, 2066 Java.

I also noticed that the absolute number of vacancies has declined substantially since my last visit, but Java by more than C#. The economy, I guess.

Is Microsoft really sweeping all before it? Well, no. Vista has disappointed; Apple sales grow ever higher; Netcraft’s web server survey shows a decline in the percentage of IIS sites on the Internet in September 2008 and observes that 75% of new web sites coming online use Apache. So it is a matter of what statistic you want to pick. Nevertheless, there is clearly still a lot of C# development out there.

Actual Android device spotted at Google Developer Day London

During the keynote at Google Developer Day London, Android evangelist Mike Jennings gave us what he says is the first showing of an actual device – prototype, of course – in Europe. I took a few blurry pics.

Perhaps inevitably, it seems reminiscent of Apple’s iPhone. It even has an accelerometer so you can code it to respond to tilts and turns.

The web browser is based on WebKit, of course.

We were shown a spinning cube created in Java using an OpenGL library. The Android SDK is based on JDK 1.5.

Another thing that was mentions is Gears for Mobile. Now that Gears has a geolocation API it will be particularly useful in this context.

Parts of EcmaScript 4 deemed unsound for the Web

5 Comments

This was the conclusion of an EcmaScript meeting in Oslo last month. Specifically, as Brendan Eich explains, three features – packages, namespaces and early binding – were considered too heavyweight unsuitable for a browser scripting language. Here is Eich’s “Executive summary”:

The committee has resolved in favor of these tasks and conclusions:

1. Focus work on ES3.1 with full collaboration of all parties, and target two interoperable implementations by early next year.

2. Collaborate on the next step beyond ES3.1, which will include syntactic extensions but which will be more modest than ES4 in both semantic and syntactic innovation.

3. Some ES4 proposals have been deemed unsound for the Web, and are off the table for good: packages, namespaces and early binding. This conclusion is key to Harmony.

4. Other goals and ideas from ES4 are being rephrased to keep consensus in the committee; these include a notion of classes based on existing ES3 concepts combined with proposed ES3.1 extensions.

This means that the evolution of JavaScript is now on a new path, focused for now on a more modest enhancement to the language called EcmaScript 3.1.

Given how loudly Eich protested about EcmaScript 3.1 last October, it is a surprising turn of events. Was Eich convinced by the arguments of Microsoft and Yahoo in support of a more lightweight JavaScript?

What this means is that JavaScript 2.0 won’t happen as previously envisaged. John Resig:

… you can forget a lot of what you learned about ECMAScript 4, previously. Many of the complicated concepts contained in the language have been tossed. Instead there is a considerable amount of effort going in to making sure that new features will be easily duplicable through other means.

Eich and Resig are keen to stress that JavaScript will still be a highly capable language. Still, the obvious conclusion is that this will be good for plug-ins which support more powerful languages: Adobe Flash, Microsoft Silverlight, Sun Java or Java/FX. Personally I’m disappointed.

It is also presenting Adobe with a tricky problem, as it implemented much of an earlier specification for EcmaScript 4 in ActionScript 3. Rather than being a standard language, as Adobe had planned, it looks like this will now be more of an Adobe language. I doubt this will have much practical impact on developers.

PS Brendan Eich has commented below.

JavaFX – just for Java guys?

5 Comments

JavaFX is Sun’s answer to Flash and Silverlight, and it’s partially open source under the GPL. I’ve just downloaded the bundle of NetBeans plus JavaFX SDK. JavaFX Script is a new language for creating rich multimedia effects. I’ve also downloaded “Project Nile”, which includes “a set of Adobe PhotoShop and Adobe Illustrator plug-ins that allow graphics assets to be easily exported to JavaFX applications”. Unlike Microsoft, Sun is choosing to work with the designer’s existing favourite tools rather than trying to wrench them away to a brand new set (Expression).

According to Sun JavaFX is happening quickly: it is promising “Version 1.0 of JavaFX desktop runtime by the fall of 2008”.

The bit that makes me sceptical, aside from the speed of events, is that if I’m reading the following diagram right, users will require both the Java Runtime Environment (could be Java ME) and the JavaFX runtime in order to enjoy the results:

By contrast, Microsoft’s Silverlight does not require the full .NET runtime to be present, making it a much smaller download; and Flash has always been small.

The win for JavaFX is access to all the services of Java:

…JavaFX applications can leverage the power of Java by easily including any Java library within a JavaFX application to add advanced capabilities. This way application developers leverage their investments in Java.

On the other hand, it means a more complex and heavyweight install for users who do not have the right version of Java itself already installed. The Windows JRE is currently around 15MB for the offline version – there’s a 7MB “online” version but my guess is that it downloads more stuff during the install. I suspect that Adobe’s Flash would never have taken off if it had been that large a download.

When I spoke to Sun’s Rich Green earlier this year I recall that he agreed that a small download was important. Maybe I have this wrong, or a smaller runtime is planned for some future date.

It’s interesting that in his official blog post today, Josh Marinacci takes a Java-centric view:

So why am I excited about JavaFX? Because it gives us the freedom to create beautiful and responsive interfaces like never before. This isn’t to say you can’t do it in plain Java. If you’ve been to any of the last 4 JavaOne’s then you’ve seen great interfaces we’ve built. But these demos were a ton of work.

Right; but you could easily build these “beautiful and responsive interfaces” in Flash, both then and now. It’s a question of positioning. Is JavaFX just a new GUI library for Java – which will be welcome, but limited in appeal to the Java crowd? Or a serious alternative to Flash? At the moment, it looks more like the former.

The messy world of the Web 2.0 user interface

Verity Stob’s Web 2.0 app diagram is worth a look.

So is it back to plain old HTML+forms then? That won’t do either; your app will look a decade old, and offline will never work.

This is why the current RIA wars are fascinating – particularly since Apple seems averse to runtimes like Flash, Java or Silverlight on its iPhone.

Which leaves what? JavaScript, hélas.

The RIA dilemma: open vs predictable

4 Comments

There’s recently been a bit of hype (RoughlyDrafted.com) for Charles Jolley’s Sproutcore, yet another JavaScript framework, mainly because Apple is using it as its “Cocoa for the Web”, according to AppleInsider.

I tried the sample controls demo in IE7 but it didn’t work quite right. For example, the Picker pane opened but would not close. Tried again in Firefox 3.0 and everything was fine.

I’ve got no idea what the problem is with IE7; it is probably because of weak standards support in IE. However, it illustrates the advantages of a plug-in like Flash, Silverlight or Java. With these platforms, the application is largely insulated from differences between browsers.

The snag with the proprietary plug-in approach is that the vendor may not support every platform equally. Microsoft is entrusting the bulk of Silverlight Linux support to a third party. There are also issues of control. Apple most likely does not want any runtimes on iPhone because they open up a route to application deployment that bypasses its App Store and 30% revenue share. Google seems wary of Flash; RoughlyDrafted says that is because of the risk of content being turned into “opaque binaries” that are beyond the reach of its contextual advertising analysis, but it may just be  reluctance to cede such an important part of its platform to a third party.

Still, as a developer in search of a predictable app platform I’d rather target a plug-in than trust the browser vendors to be sufficiently consistent, and the Javascript libraries sufficiently smart, to enable my code to run reliably everywhere. It is easier to get away with a requirement for, say, Flash 9, than to insist that users choose a particular browser or operating system.

There are other factors of course. On the Javascript + HTML side, there are advantages in that it extends rather than replaces the HTML model. Things like clipboard support just work. Plus, it runs on iPhone.

On the plug-in side, you get the fast execution of a JIT compiler, and easy use of graphical and multimedia effects that take effort to do in JavaScript, or can’t be done at all.

I would be interested in comments from developers about what RIA platform you are choosing, and why.

Sun’s bad quarter

I was interested to see Sun’s financial results after visiting the company earlier this year.

Not too good:

Revenues for the third quarter of fiscal 2008 were $3.266 billion, a decrease of 0.5 percent as compared with $3.283 billion for the third quarter of fiscal 2007 … Net loss for the third quarter of fiscal 2008 on a GAAP basis was $34 million, or ($0.04) per share, as compared with net income of $67 million, or $0.07 per share, for the third quarter of fiscal 2007.

When I visited we were told that rising income from developing nations would compensate for weakness in the USA, but apparently this is not the case. Although income from the likes of India and Brazil is rising, it is not enough to make up the difference. Another question: why is Sun under-performing relative to other companies such as IBM and Intel, both of which reported strong first quarters last month?

Sun is also set to cut 1,500 to 2,000 jobs, which suggests that the company does not expect demand to pick up soon.

The issue to me is whether Sun can make sense of its commitment to open source, or whether the proprietary guys are showing where the money really is. The MySQL purchase was great PR, but doubtful business sense.

mvn cloudtools:deploy

I love this. Write your Java EE app; then deploy to up to 20 virtual servers like this:

mvn cloudtools:deploy

The servers are Amazon EC2 instances, charged by the hour.

The tool comes from Chris Richardson, author of POJOs in Action. It combines a Groovy framework called EC2Deploy with appropriate Amazon virtual machine images and a Maven plugin. He calls the combination Cloud Tools. More on EC2Deploy here. The Cloud Tools home page is here. Open source under the Apache License 2.0.

Great for testing, could be good for live deployment too, especially now that you can get proper support from Amazon.
