What will be included in the second iteration of a horizontally scaled GitLab? We have chosen to split components even more and change the shared filesystem type. We will introduce two monitoring components.

The following diagram is of the second iteration of the High Availability (HA) solution for GitLab:

The frontend servers in the basic HA design run the Unicorn/NGINX Rails application, as well as the background jobs, via the Sidekiq component. These are all installed as part of the GitLab omnibus package. In the second iteration, you can see that the NFS server in the diagram has been replaced with a Gitaly server. Gitaly is an Remote Procedure Call (RPC) server that is specifically designed to handle Git traffic and has the ability to scale better than NFS servers, while using less bandwidth.

Evertse

Joost Evertse is an all-round professional with over 20 years of experience in IT in the financial and telecom sectors. He has worked for big and small organizations and has lived in different worlds, including Unix, Oracle, Java, and Windows. Creating order from chaos has been a big focus during his system-engineering years. After 10 years of system administration, he moved into software development and started using CI/CD tools, including GitLab. At the end of 2016, he started at a significant financial company in the GitLab team, shifting his focus more toward the entire CI/CD pipeline, with the mission of making the CI/CD platform more stable and highly available. His team eventually migrated GitLab to a private cloud and improved release cycles.
