A service is a part of a software application that performs a specific task, providing functionality to other parts of the same software application or to other software applications. Some examples of service consumers include web applications, mobile applications, desktop applications, and other services.
SOA achieves a SoC, which is a design principle that separates a software system into parts, with each part addressing a distinct concern. We discussed SoC in Chapter 6, Software Development Principles and Practices. A key aspect of SOA is that it decomposes application logic into smaller units that can be reused and distributed. By decomposing a large...
