# Messaging
## SQS
Simple Queue Service allows producers to send message to a queue and listeners to consume those messages. Oldest AWS offering. SQS is a FIFO queue, so the messages are processed in order they are sent.
## Kinesis
Real-time big data streaming.
## SNS
SNS allows you to send messages to a topic which can then have multiple receivers that perform different actions based off that.
## Amazon MQ
Fully managed message broker service for RabbitMQ and ActiveMQ. Used for migrating to the cloud to work with existing on-prem infrastructure. Doesn't scale as much as SQS and SNS.
