In the last two chapters, we discussed details related to very important elements in microservice architecture—service discovery and the configuration server. However, it is worth remembering that the main reason for their existence in the system is just to help in the management of the whole set of independent, standalone applications. One aspect of this management is communication between microservices. Here, a particularly important role is played by service discovery, which is responsible for storing and serving the network locations of all available applications. Of course, we may imagine our system architecture without a service discovery server. Such an example will also be presented in this chapter.
However, the most important components taking part in an inter-service communication are HTTP clients and client-side load balancers. In this chapter, we are going to focus just on them.
The topics we will cover in this chapter include:
