Amazon EventBridge
AWS event backbone for agents (webhooks via API destinations, cron via Scheduler). Inngest/Temporal for durable steps; QStash for HTTP-first without AWS. Strengths: Native event bus + Scheduler + Pipes + API destinations; Great AWS service fan-in for agents; Schema Registry free for custom/AWS schemas.
Strengths
- Native event bus + Scheduler + Pipes + API destinations
- Great AWS service fan-in for agents
- Schema Registry free for custom/AWS schemas
Weaknesses
- Cost surprise on custom event volume
- AWS-centric
- Not a multi-step workflow engine
Amazon SQS
Hyperscaler queue leaf when already on AWS. QStash remains Depot serverless HTTP bus default; SQS when IAM/VPC gravity wins. Strengths: Ubiquitous AWS primitive; Cheap at modest volume + Free Tier; FIFO + DLQ patterns well understood.
Strengths
- Ubiquitous AWS primitive
- Cheap at modest volume + Free Tier
- FIFO + DLQ patterns well understood
Weaknesses
- Not HTTP-callback DX like QStash
- You glue Lambdas/EventBridge yourself
- Cross-region transfer charges
