Implementing Modern Architecture

To be a successful architect, one needs to know the pros and cons of different architectures and under what conditions they are applied in a project. In addition, a good knowledge of the development process and project support in production is also very valuable.

In this course, participants will learn about the pitfalls of misapplying an architecture style and applying it to the wrong problem. We’ll also cover topics like Microservices, CQRS, Hexagonal Architecture, Event Sourcing, System stability, Development quality, and more.

Audience:

Architects, Team Leads, Senior Developers

Format:

20% workshop / 80% lecture
