What is SOA (Service Oriented Architecture)?

Question

Call me a troll if you want, but I\'m serious: how exactly is the new SOA trend any different than the client-service architecture that I was building 15 years ago?

Answer 1

A service-oriented architecture (SOA) is an architectural pattern in which softwares are designed as building block. i.e. Modular development, which makes flexibility to assemble any way we want. If you want to start new project instead of starting from scratch, we can reuse the services and if you want to new service we can easily integrate with existing service to make new project. So we can save lot of time and money.The basic principles of service oriented architecture are independent of vendors, products and technologies.

Analogy: Toys build using Lego building blocks.
