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.

This heterogeneity led into bespoke solutions to roll out versions, which are pretty much sorceries with weird habits, such as deploying at 4 a.m. to avoid an outage in the system and creating error-prone bash scripts that are harder to maintain than the software itself. The problem, aside from the complexity, is that new hires need to ramp up into your systems, and this always introduces a level of risk that we are not aware of for the majority of the time until something goes very wrong.
