Summary

In this chapter, we covered a lot of ground. We discussed the basic principle of microservices—less is more—and how breaking down your system to many small and self-contained microservices can help it scale. We also discussed the challenges that face developers utilizing the microservices architecture. We provided a slew of concepts, options, best practices, and pragmatic advice on architecting microservice-based systems. At this point, you should appreciate the flexibility that microservices offer, but also be a little apprehensive of the many ways you can choose to utilize them.

In the rest of the book, we will explore the terrain in detail and together build a microservice-based system using some of the best available frameworks and tools and deploy it on Kubernetes. In the next chapter, you'll meet Delinkcious—our sample application—that will serve as a hands-on laboratory. You will also get a glimpse into Go-kit, a microservice-based framework for constructing Go microservices.
