Summary and goal

This epic is to migrate three existing services—{}pdf-generator{}, *chrome-services, and **quickstarts—to an optimized **Graviton* instance on AWS. The primary goal is to achieve significant cost savings and performance improvements by leveraging the ARM-based Graviton architecture. The migration will involve re-building Docker images with multi-architecture support and deploying them to the new infrastructure. This initiative aligns with our broader strategy to optimize cloud spending and improve application efficiency.

Acceptance Criteria

These conditions must be met for the epic to be considered complete. This provides a detailed definition of scope and the expected outcomes, written from a user's point of view.

1. The {}pdf-generator{} service is successfully running on a Graviton instance.
2. The {}chrome-services{} service is successfully running on a Graviton instance.
3. The {}quickstarts{} service is successfully running on a Graviton instance.
4. Rollback procedures are documented in case of any issues with the new instances.

Open Questions

Capture any open questions and resolutions related to the epic goal or acceptance criteria. Add any additional details, questions or decisions that need to be made or addressed.

• {}Q:{} Are there any known compatibility issues with the ARM architecture for our current software dependencies? {}A:{} Initial research indicates the primary dependencies (Java, Node.js) have excellent ARM support. We need to verify any native libraries used by the services.
• {}Q:{} How will we handle the cutover to the new instances? {}A:{} We'll use a {}canary deployment{} or {}blue/green deployment{} strategy to minimize risk and allow for easy rollback.
