Designing Modern Service-Based Systems

From a buzzword in the early 2000s, service-oriented architecture (SOA) has evolved into an established paradigm for developing distributed software systems. But SOA today has a different face. Microservices, event-driven messaging, eventual consistency, container orchestration, and API gateways are just some of the design concepts that developers of modern service-based systems should be familiar with.

Course attendees will acquire a clear understanding of the main types of design elements and technologies that can be employed in microservice-based solutions, including REST services, platform-specific services (e.g., gRPC), message brokers, process workflow engines, and API gateways.

The course also covers security for microservices and containerization.


This course is valuable for

  • software and application architects
  • developers who use service technologies in their solutions
  • project managers and IT personnel responsible for microservice implementations


After attending this course, learners will understand

  • benefits and challenges of microservices
  • what is necessary to be successful with SOA and microservices
  • main types of components found in microservice-based solutions
  • important design considerations for microservice-based solutions

Completion of this course fulfills a training requirement for the SEI's Microservice Architect certificate program.


The following topics are covered in this class:

  • quick review of service and related concepts
  • benefits and challenges of microservices
  • the pillars of successful microservice adoption: technology, governance, and architecture
  • design considerations for REST services; services that use platform-specific component technologies; and asynchronous microservices
  • other elements used in microservice architectures: service interceptors, message brokers, API gateways, and process workflow engine
  • security for microservices
  • containerization and container orchestration


Participants will receive a digital copy of the course presentation slides and a "cheat sheet" with the most important concepts. Participants will also receive a printed Certificate of Completion at the end of the class.


Participants must have a basic understanding of distributed systems and Web-based applications.
