How we scaled GitLab for a 30k-employee company

How we scaled GitLab for a 30k-employee company

GitLab, the open source alternative to GitHub written in Rails, does not scale automatically out of the box, as it stores its git repositories on a single filesystem, making storage capabilities hard to expand. Rather than attaching a NAS server, we decided to use a cloud-based object storage (such as S3) to replace the FS. This introduced changes to both the Ruby layer and the deeper C layers. In this talk, we will show the audience how we did the change and overcame the performance loss introduced by network I/O.
