SOA Definition

[J. Acc.]

Your questions regarding SOA, and your interest in understanding what exactly SOA really is, have inspired me to put together a definition of this term. So, I went ahead and wrote one up last night. Within this paper I break the definition into ten separate points, each emphasizing an important characteristic of Service-Oriented Architecture.

The paper is published at: http://localhost/ws-standards/soa.asp
Have a look, and please respond with your comments. I hope this helps clarify things a bit.

Thomas, I'm not running a web server on my laptop
Perhaps you meant to write something other than "localhost"...?

For the benefit of all, after some url hacks, the working url is

http://www.xmltc.com/ws-standards/soa.asp

My apologies, localhost is the "staging environment" here on my workstation.

Thank you for a thorough definition Thomas.

I have a question regarding the granularity of services. At point no 4.( SOA promotes service encapsulation and reuse) you state that individual services with clearly defined functional boundaries can be composed by different parent tasks and that functions, tasks and processes all can be modelled as services.

Do you have any recommendations how coarse grained services that are exposed as Web Services should be. Could even fine grained services be exposed and wouldn't the performance hit for this make it hard in reality?

The reason that a ask is that I believe this to be very important for the re-usability of services. Too coarse grained services would be hard to re-use in different situations with different requirements.

7. SOA is based on the use of open standards.

Just wanted to know if Jiny is based on open standards?
