Building Microservices with Go

Service discovery

With monolithic applications, services invoke one another through language level methods or procedure calls. This was relatively straightforward and predictable behavior. However, once we realized that monolithic applications were not suitable for the scale and demand of modern software, we moved towards SOA or service-oriented architecture. We broke down this monolith into smaller chunks that typically served a particular purpose. To solve the problem with inter-service calls, SOA services ran at well-known fixed locations as the servers were large and quite often hosted in your data center or a leased rack in a data center. This meant that they did not change location very often, the IP addresses were often static, and ...
