Toward the end of 2016 and at the start of 2017, there was a public debate in the GitLab community about whether reverting back from the cloud to bare metal would be cost-effective for GitLab.com. At the time, the filesystem used for repositories was Ceph. The performance of that distributed filesystem was not good enough to handle GitLab.com. They asked the community for advice and received a lot of feedback from people who experienced similar moves firsthand. In the end, the decision was made to stay in the cloud (https://about.gitlab.com/2017/03/02/why-we-are-not-leaving-the-cloud/). Instead, GitLab would focus on creating a solution, not on the filesystem level, but making sure that Git input/output (I/O) behavior is better managed at the application level. This can be seen as the birth of the Gitaly component. Sid Sijbrandij emphasized the importance of being...

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.
