Course objectives
The objectives of the course are to give the students a set of skills necessary to understand and work in the context of Service Oriented Architectures (SOA), namely:
- review several issues in the business adoption of SOA in an IT context;
- give an understanding of the several definitions of SOA (as an architectural style, as an IT paradigm, ...);
- review approaches for Service Oriented Analysis and Design and how they differ from Object Oriented analysis and Design;
- review major standards in WSDL-*, together with SOAP and REST concepts;
- present concepts such as orchestration, choreography, atomic transactions, message exchange patterns;
- review major patterns in SOA in terms of security, reliability, maintainability of the implemented solutions;
- review major parts of the SOA architecture, such as Enterprise Service Bus (ESB) and solutions provided by different vendors;
- understand the differences between several architectural styles: monolith, SOA, microservices;
- practice with the creation of microservices to better understand the concepts seen during the lectures;
Learning outcomes
At the end of the course students will be able to:
- explain the meaning of the "Service Oriented" paradigm both from the business and technical point of view;
- understand the applicability of SOA design patterns and the meaning of the major SOA implementation technologies;
- compare SOA with other architectural paradigms;
- analyse requirements towards the creation of a service;
- design a service starting from the analysis phase;
- understand the problematics in service design and analysis;
- understand the problematics in service implementation;
- being able to classify and make reasoned decision about the adoption of different SOA platforms;
- know how to implement a microservices-based system;
