OpenDDS is an open-source C++ implementation of the OMG Data Distribution Service (DDS) specification for real-time publish-subscribe data distribution, with Java bindings via JNI. It supports DDS Security and XTypes, is built on the ACE/TAO abstraction layer, and runs on Windows, Linux, macOS, and Raspberry Pi.

Use cases

• implement publish-subscribe messaging between distributed C++ applications
• build real-time high-volume data distribution systems
• use DDS from Java applications via JNI bindings
• add secure data distribution with the DDS Security specification
• develop fault-tolerant distributed cache applications
• connect embedded and IoT devices with a standard data bus

When to choose

• you need an OMG DDS-compliant middleware in C++ with Java support
• your system requires real-time, reliable, high-volume publish-subscribe data distribution
• you need DDS Security or XTypes support in an open-source implementation
• you want a free, permissively licensed DDS that can be used in proprietary software

When to avoid

• you need a lightweight message broker rather than a DDS data bus
• your project uses languages other than C++ or Java
• you want a managed cloud messaging service rather than an embeddable library
• you need simple REST or queue-based messaging instead of typed pub-sub middleware
