Web Services are a technology for deploying and providing access to business functions over the Web;

A Web service is an interface that describes a collection of operations that are network accessible through standardized XML messaging.

The development lifecycle can have four phases:

1. Build

Development and testing of the Web service implementation, the definition of the service interface description and the definition of the service implementation description.

2. Deploy

The deploy phase includes the publication of the service interface and service implementation definition to a service requestor or service registry and deployment of the executables for the Web service into an execution environment (typically, a Web application server).

3. Run

During the run phase, the Web service is available for invocation.

4. Manage

The manage phase covers ongoing management and administration of the Web service application. Security, availability, performance, quality of service and business processes must all be addressed.
