Native Docker Clustering with Swarm

By: Fabrizio Soppelsa, Chanwit Kaewkasi

Overview of this book

Docker Swarm serves as one of the crucial components of the Docker ecosystem and offers a native solution for you to orchestrate containers. It’s turning out to be one of the preferred choices for Docker clustering thanks to its recent improvements. This book covers Swarm, Swarm Mode, and SwarmKit. It gives you a guided tour on how Swarm works and how to work with Swarm. It describes how to set up local test installations and then moves to huge distributed infrastructures. You will be shown how Swarm works internally, what’s new in Swarmkit, how to automate big Swarm deployments, and how to configure and operate a Swarm cluster on the public and private cloud. This book will teach you how to meet the challenge of deploying massive production-ready applications and a huge number of containers on Swarm. You'll also cover advanced topics that include volumes, scheduling, a Libnetwork deep dive, security, and platform scalability.

Microservices


The IT industry has always been keen on decoupling and reusing its creations, either source code or applications. Modeling applications at the architectural level is not an exception. Modularization was earlier called service-oriented architecture (SOA) and was kept glued by open source protocols based on XML. However, with the advent of containers, everyone is now speaking of micro services.

Micro services are small and self-contained autonomous modules that work together to accomplish an architectural goal.

The most inflated example of a micro service architecture is a web-application stack, for example WordPress, where web server might be one service, others being the database, cache engine, and the service containing the application itself. Modeling micro services through Docker containers can be done immediately and that's how the industry is moving ahead right now. 

There are many advantages of using microservices and they are as follows:

  • Reusability: You just pull the images...
