Distributed applications: APIs and web services

Service Oriented Architecture (SOA) is nowadays the main architectural style for business applications. It promotes loose coupling and interoperability, so that end-to-end business applications can easily be built from a set of business-aligned services. (SOAP) Web services and REST APIs are the most common implementations of these SOA ideas.

In this course participants get an overview of SOA principles: the concepts, the standards, the products and implementations. The evolution from the (classic) SOAP web services to REST APIs and microservices will be discussed.


No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please let us know.
