Amazon MQ

  • If you have some traditional applications running from on-premise, they may use open protocols such as MQTT, AMQP, STOMP, Openwire, WSS, etc. When migrating to the cloud, instead of re-engineering the application to use SQS and SNS (AWS proprietary), we can use Amazon MQ (managed Apache ActiveMQ) for communication.
  • Doesn't “scale” as much as SQS or SNS because it is provisioned
  • Runs on a dedicated machine (can run in HA with failover)
  • Has both queue feature (SQS) and topic features (SNS)

High Availability​

  • High Availability in Amazon MQ works by leveraging MQ broker in multi AZ (active and standby).
  • EFS (NFS that can be mounted to multi AZ) is used to keep the files safe in case the main AZ is down. attachments/Pasted image 20220509223723.jpg
