Overview of this book

GitLab is an open source repository management and version control toolkit with functions for enterprises and personal software projects. It offers configurability options, extensions, and APIs that make it an ideal tool for enterprises to manage the software development life cycle. This book begins by explaining GitLab options and the components of the GitLab architecture. You will learn how to install and set up GitLab on-premises and in the cloud, along with understanding how to migrate code bases from different systems, such as GitHub, Concurrent Versions System, Team Foundation Version Control, and Subversion. Later chapters will help you implement DevOps culture by introducing the workflow management tools in GitLab and continuous integration/continuous deployment (CI/CD). In addition to this, the book will guide you through installing GitLab on a range of cloud platforms, monitoring with Prometheus, and deploying an environment with GitLab. You'll also focus on the GitLab CI component to assist you with creating development pipelines and jobs, along with helping you set up GitLab runners for your own project. Finally, you will be able to choose a high availability setup that fits your needs and helps you monitor and act on results obtained after testing. By the end of this book, you will have gained the expertise you need to use GitLab features effectively, and be able to integrate all phases in the development process.

Summary

In this chapter, we first looked at what a basic HA architecture of GitLab should look like, and we determined the minimum amount of infrastructure that should be built. We then explained how we could do this through AWS. With Terraform, Ansible, and some scripting, we showed how you can create an HA environment with 14 hosts.

In the next chapter, we will further split the nodes and functionalities to eliminate even more single points of failure. This will grow your HA capability. Secondly, you prepare your GitLab system for serving more users because you can scale your system much more easily to accommodate the higher load.
