Amazon MQ for ActiveMQ provides durability-optimized brokers backed by Amazon Elastic File System (Amazon EFS) to support high availability and message durability. Durability-optimized brokers, backed by Amazon Elastic File System (Amazon EFS) store messages in a redundant manner across multiple Availability Zones (AZs). Active-standby brokers automatically fail over to a standby instance if a broker or AZ fails, so you can continue sending and receiving messages.
Amazon MQ also supports creating throughput-optimized message brokers backed by Amazon Elastic Block Store (EBS), perfect for use cases that require high throughput such as high-volume order processing, stock trading, text processing and many more. Throughput optimized message brokers reduce the number of brokers required, and cost of operating, high-volume applications using Amazon MQ.
