Hands-On Microservices with Kubernetes

By: Gigi Sayfan

Overview of this book

Kubernetes is among the most popular open source platforms for automating the deployment, scaling, and operations of application containers across clusters of hosts, providing a container-centric infrastructure. Hands-On Microservices with Kubernetes starts by providing you with in-depth insights into the synergy between Kubernetes and microservices. You will learn how to use Delinkcious, which will serve as a live lab throughout the book to help you understand microservices and Kubernetes concepts in the context of a real-world application. Next, you will get up to speed with setting up a CI/CD pipeline and configuring microservices using Kubernetes ConfigMaps. As you cover later chapters, you will gain hands-on experience in securing microservices and implementing REST, gRPC APIs, and a Delinkcious data store. In addition to this, you’ll explore the Nuclio project, run a serverless task on Kubernetes, and manage and implement data-intensive tests. Toward the concluding chapters, you’ll deploy microservices on Kubernetes and learn to maintain a well-monitored system. Finally, you’ll discover the importance of service meshes and how to incorporate Istio into the Delinkcious cluster. By the end of this book, you’ll have gained the skills you need to implement microservices on Kubernetes with the help of effective tools and best practices.

The future of microservices

Microservices are the dominant approach for building modern, large-scale systems today. But, are they going to remain the top choice? Let's find out.

Microservices versus serverless functions

One of the biggest questions regarding the future of microservices is whether serverless functions are going to make microservices obsolete. The answer is absolutely not. There are are many great benefits to serverless functions, as well as some serious limitations, such as cold start and time limits. Those limitations accumulate when you have functions invoking other functions. The execution time limits for function are very problematic if you want to apply retry logic with exponential backoff. A long...
