Course Overview

Service Oriented Architecture (SOA) is a standards-based architecture where business processes are represented by one-or-more independent services that may be orchestrated into new applications as needed. Services are represented by one-or-more software components. Today Web Services provide the backbone components of SOA for most organizations. This course introduces the core concepts of SOA and Web Services.
