Flexible Messaging Patterns

• Publish/subscribe for one-to-many distribution

• Work queues for task distribution among workers

• Request/reply for synchronous communication

• Topic-based routing with wildcards

• Header-based and direct routing options

• Streaming queues for high-throughput scenarios

Enterprise Reliability

• Guaranteed message delivery with acknowledgments

• Persistent messaging for durability across restarts

• Publisher confirms for delivery guarantees

• Dead letter exchanges for failed message handling

• TTL (Time-To-Live) for message expiration

• Message priorities for processing order control

Distributed Architecture

• Clustering for high availability

• Federation for connecting brokers across networks

• Shovel for message transfer between brokers

• Quorum queues for data consistency

• Mirror queues for redundancy

• Highly available queues with automatic failover

Protocol Support

• AMQP 0-9-1 as core protocol

• MQTT for IoT and mobile applications

• STOMP for web messaging

• HTTP API for management and simple operations

• WebSockets for browser-based applications

• Stream protocol for high-throughput scenarios

Developer Experience

• Client libraries for all major programming languages

• Comprehensive documentation and tutorials

• Management UI for monitoring and operations

• Command-line tools for administration

• Message tracing and debugging capabilities

• Plugin ecosystem for extended functionality

Enterprise Security

• TLS/SSL support for encrypted connections

• Authentication with username/password or certificates

• LDAP and OAuth 2.0 integration

• Fine-grained authorization with virtual hosts

• Per-vhost, per-user, and per-queue permissions

• Connection and channel limits for resource protection

Operational Excellence

• Comprehensive monitoring and metrics

• Detailed logging and audit trails

• Health checks and aliveness tests

• Resource utilization statistics

• Message rate tracking and alerting

• HTTP API for automation and management

Scalability

• Horizontal scaling with clusters

• Vertical scaling with resource controls

• Queue sharding for high-throughput

• Lazy queues for handling large message backlogs

• Connection and channel multiplexing

• Flow control to manage overload conditions

Advanced Features

• Message format validation

• Message transformation plugins

• Consistent hash exchange for balanced routing

• Priority queues for message prioritization
