I have limited knowledge of web-services; just for curiosity sake I googled SOA and tried to understand it's definition.
I am still confused and not able to understand what is SOA? Can anyone please help to understand how SOA is different from web-services?

Thanks.

As I have read on white papers and understand this: Service Oriented Architecture (SOA) is a set of concepts used to develop services that are reusable on various
areas of a company. The idea behind SOA is that it should provide a set of ‘loosely-coupled’ services that can be accessed throughout a company at any time and for multiple purposes.

One of the main differences of web services from SOA is that SOA is the definition on how the services are to be created and used, while web services can be the communication method between the SOA-developed services. Putting it in other words, web services can be used to achieve SOA. Hope that helps!
