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.

  • Integration tests: These are designed to test the integration between different components of an application and they do not test the business logic extensively. Sometimes, when the software is not very complex, the integration tests are used as unit tests (especially in dynamic languages), but this is not the most common use case.
  • Acceptance tests: Designed to test business assumptions, these are usually built on the principle of what we know as user stories describing situations with the style of being given an assumption.

Every test has a different objective, and they work well together, but keep the following diagram in your mind:
