Getting Started with Microservices

In the previous chapter, you learned what Kubernetes is all about, and how it is well suited as a platform for developing, deploying, and managing microservices, and even played a little with your own local Kubernetes cluster. In this chapter, we are going to talk about microservices in general and why they are the best way to build complex systems. We will also discuss various aspects, patterns, and approaches that address common problems in microservice-based systems and how they compare to other common architectures, such as monolith and large services.

We will cover a lot of material in this chapter:

• Programming in the small – less is more
• Making your microservice autonomous
• Employing interfaces and contracts
• Exposing your service via APIs
• Using client libraries
• Managing dependencies
• Orchestrating microservices
• Taking advantage of ownership
• Understanding Conway's law
• Troubleshooting across multiple services
• Utilizing shared service libraries
• Choosing a source control strategy
• Creating a data strategy
