In this web content, the author discusses the concept of optimization by shutting things off in order to save costs. They highlight the scenario of working in an AWS organization with numerous workload accounts and the complexity that arises when trying to support various resources and teams. The author proposes a Cloud Automation Platform that utilizes Lambda, Step Functions, and EventBridge to automate tasks such as shutting down resources during off-work hours and implementing security baseline policies. The deployment process involves using AWS AFT for baseline definition and utilizing agents in every spoke account. The author also mentions the use of EventBridge pattern matching and a configuration repository for customization. By implementing this system, the author claims to have reduced non-production costs by over 70% during off-work hours.
