In one sentence
A CloudFormation-deployed solution that starts and stops supported EC2 and RDS resources by time zone, schedule, and tags.
Core summary
DynamoDB stores schedules, Lambda executes actions, and tags select targets. Cross-account and cross-Region use requires explicit scope and authorization.
Study points
- Useful for office-hour schedules in development and test environments.
- Stop is not delete; storage, snapshots, and solution resources may still cost money.
- A stopped RDS DB instance automatically restarts after at most seven days.
- Manage Auto Scaling groups through capacity and scheduling controls.
Common pitfalls
- It is an AWS Solution, not a general managed scheduler with the same name.
- Scheduled downtime can affect dependencies, availability, and RTO.
Key memory
CloudFormation deploys it, DynamoDB stores schedules, Lambda acts, and tags choose targets.
