Opleiding: Microservices Architecture

Intro Microservices

The course Microservices Architecture starts with a discussion of the problems of monolithic applications. Subsequently the characteristics of a Microservices Architecture such as independent deployability, independent scaling and separate databases are discussed.

Design Considerations

Next it is explained how according to Conway's law the architecture of applications is reflected in the organizational structure. The switch to a Microservices Architecture therefore requires adjustments in the organization. The principles of Domain Driven Design are also treated.

Interprocess Communication

Microservices are separate processes and communicate via interprocess communication. Attention is paid to synchronous communication via REST, asynchronous communication via messaging and communication via a binary protocol such as Thrift.

Micro Frontends

Then it is time for a discussion of the user interfaces of Microservices. Various approaches for integrating a user interface are discussed such as custom elements, server side templates and built-time integration of JavaScript libraries.

Data Management

Data management in a Microservices Architecture is also covered. The different patterns for data storage such as database per service, shared database, the saga pattern and event sourcing are discussed in this respect.

Discovery and Deployment

Finally options for service discovery are covered, such as client and server side discovery and the use of service registrars. Deployment options of microservices such as in virtual machines and in containers are also treated.

Audience Course Microservices Architecture

The course Microservices Architecture course is intended for developers, architects and others who want to understand the why and how of a Microservices Architecture.

Prerequisites training Microservices Architecture

In order to participate in the course Microservices Architecture, general knowledge of software development and software design is desirable. Previous knowledge of modern programming languages ​​is beneficial to understanding.

Realization course Microservices Architecture

The theory is discussed on the basis of presentations. Illustrative demos are used to clarify the concepts. There is ample opportunity to practice and theory and practice are interchanged. Course times are from 9:30 to 16:30.

Certification Microservices Architecture

After successful completion of the course participants receive an official certificate Microservices Architecture.
