## DRI @cfeick ## Participants * @gsgl * @schin1 ## OKR https://gitlab.com/gitlab-com/gitlab-OKRs/-/work_items/8963 ## Context A number of services identified in https://gitlab.com/gitlab-com/gl-infra/platform/runway/team/-/issues/48+ have a memory-store/cache service as a key blocker in adoption of the Runway platform. This epic adds [Memorystore for Redis](https://cloud.google.com/memorystore/docs/redis) as a core capability to the Runway platform. ## Goals - Add memory-store/cache to Runway Capability - Support Regional cache services - Unblock new services onboarding ## Dependencies and Stakeholders These teams should be consulted for this project: - AI Gateway - CustomersDot ## Phases of Delivery - [x] [Experiment](https://gitlab.com/groups/gitlab-com/gl-infra/-/milestones/255) - [x] [Beta](https://gitlab.com/groups/gitlab-com/gl-infra/-/milestones/256) - [ ] GA ## Exit Criteria - [x] Cloud Run runtime supports memory-store/cache in one region - [x] Cloud Run runtime supports memory-store/cache in multiple regions - [x] Redis feature adopted by 1 or more service owners <!-- STATUS NOTE START --> ## Status 2025-02-05 **Closing status** **Problem**: Previously, Runway was limited to stateless workloads. The lack of caching capabilities was a critical blocker to platform adoption. **Solution**: The project has delivered a **paved path** for caching capabilities through managed Redis instances. Service owners can self-serve the entire lifecycle for provisioning and connecting workloads to high-availability Redis caching instances. The solution supports both single and multi-region deployments, with built-in best practices for security, cost labeling, and observability. **Impact**: The project has unblocked service adoption, unlocked platform capabilities, and established patterns for future stateful components. First, we've unblocked AI Gateway to begin reducing latency through multi-region Redis instances as they identify application use cases. Second, we've unlocked the option for Redis persistence instances that will be required for CustomersDot migration to Runway. Finally, as first stateful component, we've established architectural patterns and platform user experiences that directly benefit the Postgres on Runway initiative. **Resources**: - Documentation: https://docs.runway.gitlab.com/managed_services/redis/#using-memorystore-redis - Feedback: https://gitlab.com/gitlab-com/gl-infra/platform/runway/team/-/issues/416 **Next steps**: Based on user feedback, we will continue to iterate going forward. Grand Reviewers, please close this epic.
