Difference between wcf and azure appfabric service bus?

Question

What is the diffence between appfabric service bus and WCF?

Is service bus is an alternate for wcf on azure?

Does service bus provide all the functionality as wcf?

when to use service bus and when to use wcf in azure application?

Please help me....

Thanks in advance

Answer 1

The service bus doesn't provide services themselves - instead if provides connectivity to services - e.g. routing, scalability, security, etc.

So you will normally write your services in WCF, and can then optionally provide connectivity to those services using the bus.

This article provides a good intro to the service bus - http://msdn.microsoft.com/en-us/magazine/dd569756.aspx
