REST vs SOAP Webservices

After long time I am updating my blog since, I was very busy with my new project. Today I got some free time so thought I will update my blog with technology which I am using in my project. this time I am working on RESTful webservices ...ummm I know what next is coming in your mind..... what is RESTFul webservice and how its different from the the SOAP right ??? so here we go......
REST - stands for "Representational State Transfer", this basically means that each unique URL is a representation of some object. You can get the contents of that object using an HTTP GET, to delete it, you then might use a POST, PUT, or DELETE to modify the object (in practice most of the services use a POST for this).
SOAP - stands for "Simple Object Access Protocol" was designed to be a platform and language-neutral alternative to previous middleware techologies like CORBA and DCOM
Pros and cons of SOAP
Pros :
  • Langauge, platform, and transport agnostic
  • Designed to handle distributed computing environments
  • Is the prevailing standard for web services, and hence has better support from other standards (WSDL, WS-*) and tooling from vendors Built-in error handling (faults) Extensibility
  • Conceptually more difficult,
  • more "heavy-weight" than REST
  • More verbose Harder to develop, requires tools
Pros and cons of REST
  • Language and platform agnostic
  • Much simpler to develop than SOAP
  • Small learning curve, less reliance on tools
  • Concise, no need for additional messaging layer
  • Closer in design and philosophy to the Web
Cons :
  • Assumes a point-to-point communication model
  • Generaly not usable for distributed computing environment where message may go through one or more intermediaries
  • Lack of standards support for security, policy, reliable messaging, etc.
  • Services that have more sophisticated requirements are harder to develop ("roll your own") Tied to the HTTP transport model

Good comparison mate. REST is becoming more and more popular day by day. I have also shared some REST Interview Questions Answers, you may find useful.
