About the team

Group Tenant Scale (GTS) is building GitLab’s next generation, multi-tenant, horizontally scalable, resilient SaaS platform, at both the infrastructure and application layers, through the implementation of Cells and Organizations, respectively, and the extension of Geo to support Organization replication and cross-platform migrations. We aim to provide our customers a rock solid experience with our multi-tenant platform in terms of availability, resilience, scalability, and geolocation, and the mobility to and from our single-tenant offerings as their needs change and evolve, so that their time with us is a journey that helps them achieve their own goals and objectives.

The original team’s projects were, in essence, promoted to dedicated teams, with the addition of Geo to help us build the future of GitLab’s multi-tenant offering.
