Chapter 2. Red Hat JBoss AMQ 7
2.1. Overview
Based on the upstream Apache ActiveMQ and Apache Qpid community projects, Red Hat JBoss AMQ 7 is a lightweight, standards-based open source messaging platform designed to enable real-time communication between different applications, services, devices, and Internet of Things (IoT) devices. It also serves as the messaging foundation for Red Hat JBoss Fuse, Red Hat’s lightweight, flexible integration platform, and is designed to provide the real-time, distributed messaging capabilities needed to support an agile integration approach for modern application development.
AMQ 7 introduces technology enhancements across three core components: the broker, clients, and Interconnect router.
2.2. Broker
The AMQ 7 broker, based on Apache ActiveMQ Artemis, manages addresses, queues, and routing semantics. The new broker has an asynchronous internal architecture which can increase performance and scalability, while enabling it to handle more concurrent connections and achieve greater message throughput. AMQ Broker is a full-featured, message-oriented middleware broker. It offers specialized queueing behaviors, message persistence, and manageability. Core messaging is provided with support for different messaging patterns such as publish-subscribe, point-to-point, and store-and-forward. AMQ 7 supports multiple protocols and client languages, allowing integration of many, if not all, application assets.
2.3. Clients
Red Hat JBoss AMQ 7 expands its support of popular messaging APIs and protocols by adding new client libraries, including Java Message Service (JMS) 2.0, JavaScript, C++, .Net, and Python. With existing support for the popular open protocols MQTT and AMQP, AMQ 7 now offers broad interoperability across the IT landscape that can open up data in embedded devices to inspection, analysis, and control.
2.4. Interconnect
The new Interconnect router in AMQ 7 enables users to create an internet-scale network of uniformly-addressed messaging paths spanning data centers, cloud services, and geographic zones. The Interconnect component serves as the backbone for distributed messaging, providing redundant network pathing for fault handling, traffic optimization, and more secure and reliable connectivity.
