Overview of this book

This book follows a unique approach to modern DevOps using cutting-edge tools and technologies such as Ansible, Kubernetes, and Google Cloud Platform. This book starts by explaining the organizational alignment that has to happen in every company that wants to implement DevOps in order to be effective, and the use of cloud datacenters in combination with the most advanced DevOps tools to get the best out of a small team of skilled engineers. It also delves into how to use Kubernetes to run your applications in Google Cloud Platform, minimizing the friction and hassle of maintaining a cluster but ensuring its high availability. By the end of this book, you will be able to realign teams in your company and create a Continuous Delivery pipeline with Kubernetes and Docker. With strong monitoring in place, you will also be able to react to adverse events in your system, minimizing downtime and improving the overall up-time and stability of your system.

Chapter 7. Docker Swarm and Kubernetes - Clustering Infrastructure

So far, we have seen how powerful Docker is but we have not unleashed the full potential of containers. You have learned how to run containers on a single host with the local resources without the possibility of clustering our hardware resources in a way that allows us to uniformly use them as one big host. This has a lot of benefits, but the most obvious one is that we provide a middleware between developers and ops engineers that acts as a common language so that we don't need to go to the ops team and ask them for a machine of a given size. we just provide the definition of our service and the Docker clustering technology will take care of it.

In this chapter, we are going to dive deep into deploying and managing applications on Kubernetes, but we will also take a look at how Docker Swarm works.

People usually tend to see Kubernetes and Docker Swarm as competitors, but in my experience, they solve different problems:
