In this course, you will be introduced to the fundamentals of Service Oriented Architectures (SOA) and the core standards that enable web services. You will focus on what separates an ad hoc set of web services (NOT SOA) from a managed, vibrant, reusable catalog of enterprise services (definitely SOA). You will examine the entire spectrum from the promise of cloud computing to the grit of XML content. You will get a clear picture of how a service orientation can fundamentally change the dynamics of how software is developed and "lives" within an enterprise. You will gain a better understanding of the fundamental technologies used in web services. This understanding is critical to being able to diagnose, troubleshoot, tune, and perform other life-cycle activities. You will leave the course armed with the required skills to design, implement, test, and support J2EE web services.

Skills Gained

  • Basic concepts of SOA to the identification and design of web services
