A service is a software component with a functional meaning that distinguishes it from others, and typically encapsulates a high-level business concept. Figure 2 shows the elements that are part of a service.

Application frontends are the active elements of SOA architecture. They initiate and control all activities on corporate systems. There are different types of frontends. An application frontend can present a graphical user interface, such as a Web application or a rich client that interacts directly with end users.

Ultimately, it is always an application frontend that initiates a business process and receives the results. Application frontends are similar to the top-level layers in traditional multi-tier architectures.
