Why to go for Rest Services

When should we go for Rest Services? How does it help us in scaling the application? 

Yes .Rest Servives provides a better option to handle a complex application where we expect heavy load and we expect continuously addition of components.

Reasons to go with Rest Services are :

• Simple.
• We can deploy the services to any remote location so that load on the server will be reduced.
• If we find that a specific services are consumed heavily we can distribute those services to a different server.We may not nead to use load balancer.
•  You can make good use of HTTP cache and proxy server to help you handle high load.
• It helps you organize even a very complex application into simple resources.
• It makes it easy for new clients to use your application
•  It makes it easy for new clients to use your application, even if you haven't designed it specifically for them  probably, because they weren't around when you created your app.
• Also, because REST relies on the semantics of HTTP, requests for data (GET requests) can be cached.
