Question

Nightly municipal batch jobs currently depend on cron on a single EC2 server. How should scheduling be modernized for resilience and scale?

Accepted Answer

Replace single-server cron with Amazon EventBridge Scheduler (or EventBridge rules) invoking AWS Lambda on a managed schedule. — EventBridge Scheduler is the city’s reliable night watch—no single dusty cron box to fail. Sticky notes and random traffic aren’t schedules; they’re hopes.

Answer

Keep cron on one instance and add a sticky note reminding operators to reboot if the host dies.

Answer

Schedule jobs only by waiting for random citizen traffic to trigger side effects.

Answer

Move cron into a Lambda deployment package but still require that one EC2 host to be online to fire it.
