The aim is a loose coupling of services with operating systems, programming languages and other technologies which underlie applications.SOA concepts are often seen as built upon, and evolving from older concepts of distributed computing and modular programming.

- Interoperability between different systems and programming languages provides the basis for integration between applications on different platforms through a communication protocol
- Create a warehouse of resources.
