Our presentation has three major parts/goals:
A) brief review of SOA and SOA Web Services
B) discussion of the relevant points for the three case studies identified in the reading for this week (see below for the reading material)
C) interactive discussion of several business scenarios where we discuss whether SOA is a proper alternative
Note that the other presentation this Tuesday will be on the same topic of SOA Web Services. Our intention is to minimize any overlap between the two presentations.
Class interaction will add to the presentation & is encouraged.
The reading below is relatively light and is on one website => http://www.cioinsight.com/c/b/Case-Studies/
1) British Telecom Case Study - a very short case detailing how British Telecom pursued SOA as its strategy as it standardized its world-wide IT operations.
2) Valero Case Study - this case provides the background of why Valero pursued SOA along with its experiences with building services.
3) Amazon Case study - this case study is a second look for the class at the several services provided by Amazon from another perspective.

What is that "service" in SoA and Web Services? How is it different? Here are some of my thoughts on its major characteristics:
ReplyDelete- Software components/modules
- Defined interfaces
- Publicly accessible (open)
- Clear service description (self-describing)
- Standard protocol
- Self-contained, focusing on results
- Distributed
- Serving applications, not humans
Then, the question is: why are services good (or not) for application integration?
Are services good (or not good) for application integration?
ReplyDeleteWell, from what I have heard services are currently supposed to be as best as it goes when it comes to application integration. Additional characteristics include loosely-coupled and language independent. Meaning that services tend not to break easily and that you are not tied to using specific languages to make use of services.
