Chapter walkthrough#

This chapter shows an implementation for a synchronous microservices system with Consul and the Apache httpd server.

Essential contents of the chapter are:

  • Consul is a very powerful service discovery technology.

  • Apache httpd can be used as a load balancer and router for HTTP requests in a microservices system.

  • Consul Template can create a configuration file for the Apache httpd server that includes information about all registered microservices. Consul Template configures and restarts Apache httpd when new microservice instances are started.
