Ship and stay up. CI/CD pipelines, Kubernetes setups, monitoring and the self-hosting playbooks that cut our own cloud bill.
These parts come from running our own server, not from a slide deck. The shared goal is turning deployment from an event you brace for into a routine, with defensive scripts and well-built pipelines doing the boring, reliable work.

That is what Cost Optimization and the self-hosting playbooks are for: including Customer Meilisearch Selfhost, which replaced a paid search service with a self-hosted one in our own stack. Real migrations, with the gotchas written down.
Deployment Pipeline Design. It turns deploys from an event into a routine: staged pipeline, rollback path, checks that run before anyone holds their breath. Frequency follows safety.
Opinionated defaults, documented escape hatches. Manifests and Bazel Build Optimization carry the choices we run in production, with notes on where and why you would diverge.
