MQTT and AMQP Clients in ABAP
MQTT (Message Queuing Telemetry Transport) protocol is used for machine-to-machine (M2M) communication and within Internet of Things (IoT) scenarios and based on publish-subscribe infrastructure.
AMQP (Advances Message Queuing Protocol) is an open internet protocol for robust and asynchronous messaging. AMQP allows point-to-point and publish-and-subscribe communications.

Security Features
Unified Connectivity (UCON) framework allows you to secure RFCs by drastically reducing the number of remote-enabled function modules that can be accessed from outside, thus dramatically reducing the potential attack surface

SAP recommends receiver validation to control destination usage in outgoing HTTP(S) connections. This feature improves your security by helping to prevent the insecure practice of destination sharing - that is many applications using the same destination.
