Introduction
In this lesson, we'll get a walkthrough of what this chapter holds for us.
We'll cover the following
Why are microservices so important?#
One of the strengths of microservices is that different technologies can be used in each individual microservice.
The technologies in the microservices can be defined as part of the microarchitecture (see chapter 3).
However, there are technical challenges to consider when selecting technologies for microservices.
Chapter walkthrough#
This chapter explains how to deal with the technical microarchitecture:
-
The reader gets to know the requirements regarding, e.g., operation or resilience, which the microarchitecture has to fulfill.
-
Often microservices are implemented with reactive technologies. Thus, the chapter discusses this option in more detail and explains when this approach makes sense.
-
As a concrete example of technical microarchitecture, the chapter shows Spring Boot and Spring Cloud.
-
Based on Spring Boot and Spring Cloud, the chapter shows how the technical requirements the microarchitecture has to address can be fulfilled.
-
In addition, the chapter shows how the programming language Go in conjunction with appropriate frameworks fulfills the requirements for implementing microservices.
Quiz#
Which technology are microservices often implemented with as stated above?
A)
REST
B)
Reactive
C)
HTTP
In the next lesson, we’ll start with the first point from the list above and discuss the requirements, a technology for implementing microservices has to fulfill.
