Q: What is Amazon MQ?
Amazon MQ is a managed message broker service for Apache ActiveMQ that makes it easy to set up and operate message brokers in the cloud. Amazon MQ manages the administration and maintenance of ActiveMQ, a popular open source message broker. Amazon MQ supports durability-optimized brokers backed by Amazon Elastic File System (Amazon EFS) to support high availability and message durability, and throughput-optimized brokers backed by Amazon Elastic Block Store (EBS) to support high-volume applications that require low latency and high throughput. With Amazon MQ, you get direct access to the ActiveMQ console and industry standard APIs and protocols for messaging, including JMS, NMS, AMQP, STOMP, MQTT, and WebSocket. You can easily move from any message broker that uses these standards to Amazon MQ because you don’t have to rewrite any messaging code in your applications.
Q: Who should use Amazon MQ?
Amazon MQ is suitable for enterprise IT pros, developers, and architects who are managing a message broker themselves–whether on-premises or in the cloud–and want to move to a fully managed cloud service without rewriting the messaging code in their applications.
Q: What does Amazon MQ manage on my behalf?
Amazon MQ manages the work involved in setting up a message broker, from provisioning the infrastructure capacity you request–including broker instances and storage–to installing the broker software. Once your broker is up and running, Amazon manages ongoing software upgrades, security updates, and fault detection and recovery. Amazon MQ stores messages redundantly across multiple Availability Zones (AZs) for message durability. With active/standby brokers, Amazon MQ automatically fails over to a standby instance in the event of a failure so you can continue sending and receiving messages.
Q: What is an Amazon MQ network of brokers?
Amazon MQ uses the “network of brokers” feature that is part of Apache ActiveMQ. A network of brokers consists of multiple brokers connected together. Brokers in the network share information about the clients and destinations each broker hosts. The brokers use this information to route messages through the network. With Amazon MQ, the brokers in the network can either be active-standby brokers (each active broker in the network has a standby node, with shared storage, that will take over if the active node fails), or single-instance brokers (if the node fails, it will be unavailable until it is restarted). Each broker in the network maintains its own unique message store which is replicated across multiple AZs within a region. The nodes in the network forward messages to each other, so messages are stored by a single broker at any given time.
You should use network of brokers if you require high availability with fast reconnection in the case of broker failure, or if you need the ability to scale horizontally.
Q: When would I use Amazon MQ vs. managing ActiveMQ on Amazon EC2 myself?
The choice depends on how closely you want to manage your message broker and underlying infrastructure. Amazon MQ provides a managed message broker service that takes care of operating ActiveMQ, including broker set up, monitoring, maintenance, and provisioning the underlying infrastructure for high availability and durability. You may want to consider Amazon MQ when you want to offload operational overhead and associated costs. If you want greater control in order to customize features and configurations or to use custom ActiveMQ plugins, you may want to consider installing and running ActiveMQ on Amazon EC2 directly.
Q: How do I migrate if I'm using a different message broker instead of ActiveMQ?
Amazon MQ provides compatibility with the most common messaging APIs, such as Java Message Service (JMS) and .NET Message Service (NMS), and protocols, including AMQP, STOMP, MQTT, and WebSocket. This makes it easy to switch from any standards-based message broker to Amazon MQ without rewriting the messaging code in your applications. In most cases, you can simply update the endpoints of your Amazon MQ broker to connect to your existing applications, and start sending messages.
Q: How does Amazon MQ work with other Amazon Web Services services?
Any application that runs on an Amazon Web Servicescompute service, such as Amazon EC2, Amazon ECS, or Amazon Lambda, can use Amazon MQ. Amazon MQ is also integrated with the following Amazon Web Services services:
- Amazon CloudWatch - monitor metrics and generate alarms
- Amazon CloudWatch Logs - publish logs from your Amazon MQ brokers to Amazon CloudWatch Logs
- Amazon CloudTrail - log, continuously monitor, and retain Amazon MQ API calls
- Amazon CloudFormation - automate the process of creating, updating, and deleting message brokers
- Amazon Identity and Access Management (IAM) - authentication and authorization of the service API
- Amazon Key Management Service (KMS) - create and control the keys used to encrypt your data
Q: What kind of messaging durability does Amazon MQ provide?
Amazon MQ provides durability-optimized brokers backed by Amazon Elastic File System (Amazon EFS) to support high availability and message durability. When the ActiveMQ broker is used in persistent mode, each message is redundantly stored across multiple Availability Zones (AZs). With durability-optimized brokers, the message store can be accessed concurrently from all AZs in the region where it is located, which means that the message broker can fail over from one AZ to another AZ in the region without message loss. Amazon MQ is designed for 99.999999999% (eleven 9’s) message durability.
Q: How can I get started with Amazon MQ?
Amazon MQ makes it easy to setup and operate message brokers in the cloud. With Amazon MQ, you can use the Amazon Web Services Management Console, CLI, or API calls to launch a production-ready message broker in minutes. In most cases, you can simply update the endpoints of your Amazon MQ broker to connect to your existing applications and start sending messages.
Q: How am I charged for Amazon MQ?

Q: How do I use my own custom keys to encrypt the data in Amazon MQ?
Amazon MQ supports the Amazon Key Management Service (Amazon KMS) to create and manage keys for at-rest encryption of your data in Amazon MQ. When you create a broker, you can select the KMS key used to encrypt your data from the following three options: a KMS key in the Amazon MQ service account, a KMS key in your account that Amazon MQ creates and manages, or a KMS key in your account that you create and manage. In addition to encryption at rest, all data transferred between Amazon MQ and client applications is securely transmitted using TLS/SSL.
Q: How can I monitor my broker instances, queues, and topics?
Amazon MQ and Amazon CloudWatch are integrated so you can view and analyze metrics for your broker instances, as well as your queues and topics. You can view and analyze metrics from the Amazon MQ console, the CloudWatch console, the command line, or programmatically. Metrics are automatically collected and pushed to CloudWatch every minute.
Q: Does Amazon MQ have a Service Level Agreement?
Yes. Amazon Web Services will use commercially reasonable efforts to make Active/Standby Brokers available with a Monthly Uptime Percentage of at least 99.9% during any monthly billing cycle (the "Service Commitment"). In the event Amazon MQ does not meet the Monthly Uptime Percentage commitment, you will be eligible to receive a Service Credit. For details, please review the Amazon MQ Service Level Agreements for Ningxia or Beijing.
Q: What type of storage is available with Amazon MQ?
Amazon MQ supports two types of broker storage – durability optimized using Amazon Elastic File System (Amazon EFS) and throughput optimized using Amazon Elastic Block Store (EBS). To take advantage of high durability and replication across multiple Availability Zones, use durability optimized brokers backed by Amazon EFS. To take advantage of high throughput for your high volume applications, use throughput optimized brokers backed by EBS. Throughput optimized message brokers reduce the number of brokers required, and cost of operating, high-volume applications using Amazon MQ.
