What are the advantages of web services?

Interoperability: Using web services, an application can communicate with other application developed in any language.

Reuability: We can expose the web service so that other applications can use it.

Modularity: Using web service, we can create a service for a specific task such as tax calculation etc.

Standardized Protocol: Web services use standardized industry standard protocol for the communication. All the four layers (Service Transport, XML Messaging, Service Description, and Service Discovery layers) use well-defined protocols in the web services protocol stack.
