/Automate. Serverless and event-driven approach to DevOps
summary
Serverless AWS glue ties Slack to a multi‑account platform: API Gateway and Lambda parse slash commands, publish envelopes to Amazon EventBridge, and per‑account Step Functions and tiny Lambda “nano‑services” run sagas to start RDS, scale ECS, start VPNs and reset IP allowlists. Outcome: 60% cost reduction from scheduled shutdowns and scale‑down, EventBridge and Step Functions power domain separation and retries, and an automated allowlist reset nightly with Slack progress updates and auditable events.
