[ 1. Amazon MQ ]

- Amazon MQ = managed Apache ActiveMQ

- SQS, SNS are cloud-native services and they're using proprietary protocols from AWS

- Traditional applications running from on-premise may use open protocols such as : MQTT, MAQP, STOMP, Openwire, WSS

- when migrating to the cloud, instead of re-engineering the application to use SQS and SNS, we can use Amazon MQ

- Amazon MQ doesn't "scale" as much as SQS/SNS

- Amazon MQ runs on dedicated machine, can run in HA(High Availability) with failover

- Amazon MQ has both queue feature(~SQS) and topic features(~SNS)

- active/standby structure (failover)

[ 2. SQS vs SNS vs Kinesis ]
