Self-hosted SQS alternative with ElasticMQ, practical for cloud cost optimization and infrastructure.
Summary
ElasticMQ provides an in-memory message queue with an SQS-compatible REST API, deployable via Docker behind Traefik with TLS for dev, test, or production use without AWS dependency. It supports standard/FIFO queues, dead-letter queues, visibility timeouts, and optional H2 database persistence, while lacking SQS features like server-side encryption and CloudWatch integration. The deployment requires two subdomains (API and UI) due to the web UI's absolute path requirements, and uses HOCON configuration files to define queues and DLQ policies.
