In a new post to his blog Juozas Kaziukenas takes a look at one of the pieces of "glue" that makes up the typical web application - the service layer.

During this year I invested quite a lot for a search of a good ways to architecture a big application and make it simply good. Quite a while ago Matthew Weier O'Phinney introduced service layer in one of his great talks about models, since then service layer become one of the key architectural component one my applications. Here I'm going to show a few examples and use cases where it's very useful.

He looks at the "old style" of data interaction that several applications use as compared to injected objects and information more structured applications have put to use. He also outlines a practical use of the service layer structure - thinking of it as a layer allowing to you connect to a service, either local or remote, without the rest of the application needing to know about it.
