Chapter 13

The Future of Web Services

The technologies used to build Web services and the ways developers leverage these technologies are in their infancy. At the time of this writing, standards bodies are well underway drafting the next version for a number of existing specifications such as SOAP and UDDI. In addition, companies are developing new and creative uses for Web services.

In this chapter, I first examine a set of Web services currently in development within Microsoft that is receiving a considerable amount of attention—Microsoft .NET My Services. Microsoft .NET My Services exposes a number of Web services that allow users to control their personal data. Among these are a set of user-focused Web services that allows users to store their personal information securely in remote locations and then access it from any device in any location and even allows others to access it (but strictly on terms the user defines). I explain how you can leverage .NET My Services from within your own applications.

The existing suite of industry-standard specifications that define Web services has some significant omissions. In many cases, developers are stifled with respect to the type of services that they can provide their customers. In the case of .NET My Services, I point out areas that are not covered by the current set of Web service specifications.

In an effort to fill in gaps not covered by the current set of Web service specifications, Microsoft introduced the Global XML Web Services Architecture (GXA). At the time of this writing, the GXA consists of five specifications that address key areas not covered by current industry standards. Once the specifications mature, Microsoft intends to turn over the specifications to recognised standards bodies so that they can be ratified and released as recommendations. In this chapter, I provide a brief overview of all five specifications.

Finally I examine some of the emerging infrastructural components for developing and deploying Web services. Specifically, I provide a brief explanation of Microsoft's plans to provide dynamic application topologies, the ability to host a Web service across a number of geographically distributed servers. I also review the BizTalk Orchestration for Web Services technical preview.

note

The material in this chapter is based on beta software and specifications, so changes are likely prior to final release.
