Fact Check – IBM’s Steve Mills claims on MS and SOA
We saw an article on CNET that included quotes from Steve Mills of IBM directly related to Interop, SOA and Microsoft. Since Interop is one of our passions, we thought it would be worthwhile to respond. Given that we are approaching an election here in the US, we are employing a CNN technique. Let's check the facts.
Claim: Steve Mills is Senior VP of IBM Software.
Microsoft Fact Check: TRUE. Mr. Mills runs IBM Software, which is about a USD $18B business for IBM. By the way, IBM Software Group contributes about 40% of IBM's pre-tax profit, according to a recent ComputerWorld article.
Claim: Microsoft's approach to SOA [is] stymied by its emphasis on linking Microsoft-compatible processes. "We're doing all platforms; all applications," IBM Software Group executive Steven Mills told ZDNet.co.uk. "We're integrating everything. Microsoft is trying to provide connectivity capabilities for those that are running on Windows platforms. That's a profound difference."
Microsoft Fact Check: Mr. Mills seems to be commenting on Microsoft SOA infrastructure software, including the .NET Framework (and WCF, and WF, and all the constituent technologies), BizTalk Server, Host Integration technologies, and so on. If the claim is that this Microsoft software runs only on Windows, then this is TRUE. This is not a particularly novel, interesting or relevant observation. Incidentally, it applies to Mr. Mills' portfolio as well: CICS and IMS for example. Or consider DB2: it runs on many systems, but the capabilities in the mainframe version differ from those versions for other platforms.
Mr. Mills seems to be saying something different: he seems to be implying, because BizTalk Server (as one example) runs only on Windows, then it can connect only to other Windows-based systems or applications. That is FALSE. The facts are: the vast majority of the over 7,000 BizTalk Server customers use the technology to connect with assets on UNIX, Linux and mainframe based systems: 92% perform heterogeneous platform integration. In fact, Microsoft has long offered a technology that does nothing but integrate with IBM's iSeries and zSeries technologies. (it accomplishes this via IBM's proprietary protocols, which Microsoft must license).
Claim: "Their perspective is how to make Windows environments connect, as long as you're using Microsoft technology. Our view is: how do you make every environment connect whether you are using Microsoft or anyone else's technology," Mills said.
Microsoft Fact Check: This is the continuation of Mr. Mills' previous thought. In virtually every enterprise above a certain size or age, the rule is heterogeneity in IT. Whether you're an international bank, a specialty manufacturer, or a chain of sushi restaurants, there's a myriad of information systems and applications you need to deal with, and better connections among those systems allows you to run your business better. That's what SOA is about, and that's what Microsoft's SOA platform infrastructure is designed to help with. Thus, FALSE.
Claim: Mills claimed there is a big difference between IBM and Microsoft's approaches, saying that, in contrast to Microsoft, IBM uses open standards for XML and web services.
Microsoft Fact Check: FALSE. Implying that Microsoft does not support standards like XML and WS-* is odd. This denies the reality of the past 7 years, during which Microsoft has repeatedly been recognized by independent analysts as leading the industry drive toward defining and implementing open protocol standards such as XML, and WS-*. It is also an attempt to revise history as Microsoft and IBM partnered on Web Services Standards in 1999 which led to the original specifications. Mr. Mills himself stood up with Bill Gates to talk about the two companies' collaboration on these standards. Moreover, Microsoft and IBM have continuously defined additional Web service specifications and publicly tested interoperability. Examples include WSDL, WS-Security, WS-ReliableMessaging, etc.
But let's talk specifics. Take one example: XML Serialization. XML Serialization has been part of the .NET Framework since v1.0. XML Serialization allows a developer to map between instances of objects in a program, and instances of XML documents, very simply. This is a key interop-enabling capability; it means, in part, that a .NET application running on Windows can very simply emit an XML instance document that can then be consumed by any other XML-capable application, running on any other platform. Or vice versa. And it's a foundation for other, higher-level interop capabilities: start with XML Serialization and add in message transport and tools, and you then can get Web services.
This XML support has continued through the versions of .NET across the years, and has been expanded significantly. WCF, shipped in .NET 3.0 in December 2006, added some new capabilities and more mature models – dealing with XML in .NET apps is now both easier and more flexible. The list of open standard protocols supported in WCF includes: HTTP1.1, XML, SOAP1.1, SOAP1.2, WS-Addressing, XOP, MTOM, WS-Security (including x.509, Kerberos, and SAML 1.1 token profiles), WS-Policy, WS-Trust, WS-Coordination, WS-AtomicTransaction, WS-SecureConversation, WSDL 1.1, WS-MetadataExchange, WS-Transfer. Looking forward, in the .NET Framework v3.5 (currently at beta 2), we've included support for REST-style web services, as well as internet syndication protocols like ATOM and RSS, and other protocols like JSON.
Microsoft does support optimized protocols and formats in WCF for Windows-to-Windows communication. IBM provides similar optimizations for their products, as do all SOA platforms.
Claim: Microsoft and IBM have tussled over XML standards.
Microsoft Fact Check: TRUE. But, like the observation that Windows is the OS that underlies Microsoft SOA infrastructure, this is not an interesting part of the story. The picture that is painted by the article would lead one to suspect that a tussle over standards is exclusionary or at least stalling productivity. Coexistence of multiple standards and encouraging market participation in standards evolution is paramount. The OOXML / ODF point in the article is like saying you won't be able to send digital pictures to your mom because there isn't a single standard for graphic presentation. Clearly there are multiple standards for digital images, gif, jpeg, png and so on - which has arguably helped drive utilization. The far more important point is implementation of multiple standards which Microsoft technology does.
OOXML and ODF are about documents. Discussion of documents needs to include all standards, many of which Microsoft supports and has lead. Examples include HTML, CSS, etc.
Claim: "The [Microsoft] MSDN mechanism is a lightweight messaging infrastructure in a message-based environment, whereas IBM delivers a fully functioning infrastructure," [Mr. Mills] said.
Microsoft Fact Check: FALSE, judging from the wide variety of customer case studies that describe how customers utilize .NET and the rest of the Microsoft platform to broadly exploit the benefits of SOA. Microsoft customers use the Microsoft SOA infrastructure to run the core information systems that power their businesses. IBM's Web sites discusses the "entry points" to SOA. Microsoft has equivalent products in Microsoft Office Sharepoint, IIS/ASP.NET, BizTalk Server, WCF, Visual Studio and adaptors for existing applications.
As a side note, MSDN is a developer-outreach program, including a website, a software subscription and licensing offering, a magazine, and more. It's not directly related to SOA infrastructure. IBM has developerWorks, which is similar in intent.
In Closing
Do you want to know just how serious we are about Interop and Performance? Take a look at our .NET Stock Trader application which we modeled after IBM's Trade 6.1 performance application. We've demonstrated our ability to interoperate with applications that run on other platforms including IBM WebSphere applications running on Windows, Linux, or Unix™ . Don't miss this part: the .NET application duplicates the function of the Websphere app, but with far better performance.
