What is the operational cost of maintaining a Temporal deployment vs using Diagrid Catalyst (excluding licensing)?

Temporal self-hosted requires dedicated ops for database clusters, history service, and visibility stores, plus ongoing tuning for scalability. Temporal Cloud reduces this but still involves workflow management overhead. Catalyst eliminates these by being a fully managed service: no infrastructure to maintain, automatic scaling, and built-in monitoring. The operational cost shifts from infrastructure management to application logic, which can lower total team effort, especially for smaller platform teams.
