I wish I discovered this earlier and AWS had built this earlier too.
I had a similar use-case at work but Event Bridge Scheduler was not available at that moment, only cron scheduling was available.
so I decided to build my own date based scheduler ( open sourced it recently)
Nice Article Sandro
EventBridge Scheduler is such a game-changer for this kind of workload! Ὄ5
Moving away from CRON-based scheduling to event-driven architecture was absolutely the right call. The resource efficiency gains alone must be significant - no more idle processes waiting around.
I"m curious about the migration process - did you run both systems in parallel during the transition? And how did you handle existing scheduled posts that were already in the CRON queue?
The CDK implementation looks clean. I especially appreciate how you"ve structured the scheduler configuration. For content creators, reliable post scheduling is crucial for their workflow - this kind of behind-the-scenes infrastructure work directly impacts user productivity.
This pattern could work well for many time-based operations beyond just publishing. Great technical write-up! Ὦ0️
