The hexagonal architecture, or ports and adapters architecture, is an architectural pattern used in software design.It aims at creating loosely coupled application components that can be easily connected to their software environment by means of ports and adapters.
Tavendo, the company from which originated the protocol, is also the author of Crossbar.io, which promotes itself as the de facto router implementation. [14] As they are promoting microservice-based architectures, Crossbar.io embeds a service manager for hosting and monitoring WAMP app components, a static file Web server, and a WSGI container.
The Data Distribution Service (DDS) for real-time systems is an Object Management Group (OMG) machine-to-machine (sometimes called middleware or connectivity framework) standard that aims to enable dependable, high-performance, interoperable, real-time, scalable data exchanges using a publish–subscribe pattern.
