Real World SOA: Design and Implementation
This course is a continuation of the course 'Real World SOA: Analysis and Design.' In that course, you studied SOA analysis and overall design, here you will get more detailed about implementation.
What you'll learn
In the Analysis and Design course you covered the business aspects of SOA and SOA reference architecture building blocks. In this course, Real World SOA: Design and Implementation, you'll move into the detailed design and implementation of SOA services. First, you'll look into the design principles that drive the entire design effort and the structure and dynamics of services. Then, you'll learn the different MEPs supported by services and the management of state, sessions, and client-service interactions. Finally, you'll learn the security of services, and various other topics. By the end of this course, you'll learn all you need to know about the design and implementation of SOA.
