 1.Loose Coupling : This means that the service requester has
 no knowledge of the technical details of the provider’s 
implementation, such as the programming language, 
deployment platform, and so forth. The service requester 
typically invokes operations by way of messages — a request 
message and the response — rather than through the use of APIs or file formats.
