Mastering Service Mesh

By: Anjali Khatri, Vikram Khatri

Overview of this book

Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment. You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability. By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.

Container orchestration platforms

The container revolution for software virtualization led to the development of container orchestration platforms such as Docker Swarm, Apache Mesos, Kubernetes, Cloud Foundry, and so on in order to be able to quickly deploy containers in a distributed environment.

Let's discuss a few of them:

  • Since Docker was already famous, it started its own Docker Swarm (https://docs.docker.com/engine/swarm) as an orchestration platform. Swarm has tight integration with the main Docker API. Swarm runs an agent on each host, and a Swarm manager runs on one host. This manager is responsible for scheduling containers on a proper host when you issue the docker run command.
  • Apache Mesos (http://mesos.apache.org) is a distributed cluster manager and has similar capabilities to Google Project Borg or Facebook's Tupperware. It was adopted by Twitter, Apple...
