For production environments, our deployment recommendations for a good baseline always include:
- Three availability zones for high availability.
- Three runners that hold the director and coordinator roles, spread across three availability zones.
- As many runners that hold the allocator role as needed for the workload you’re planning to run, spread across three availability zones.
- Enough runners that hold the proxy role to handle the volume of user requests, or at least one per availability zone for high availability. In the playbook examples, we always use three.
If you are setting up a production system, take a look at the examples in our Playbook for Production. The playbook provides sample installation commands that follow these recommendations and are tailored to different deployment sizes and high availability.
