Gitlab’s Journey from Azure to GCP

To address these challenges, we decided to migrate from Azure to Google Cloud Platform (GCP) and document the journey publicly, end to end. At Google Cloud Next ’19, GitLab Staff Engineer Andrew Newdigate presented our migration experience and the steps we took to make it happen. We hoped that by taking advantage of the replication capabilities we were building for Geo, we could migrate the entire GitLab.com site to a secondary instance in GCP.
