Matrix42 Secure Unified Endpoint Management uses a communication architecture based on an enterprise service bus. This allows a more efficient and faster communication between the UUX for SUEM, Empirum, Silverback and EgoSecue. The goal is that the entire communication between the SUEM core product parts will take place over it in order to also enable hybrid installations, (e.g. Empirum and EgoSecure local, Silverback and Solution Builder in the Cloud).
Azure Service Bus for Cloud or RabbitMQ for on premise installations are currently supported as Service Bus. Read the documentation for the respective installation or configuration in the corresponding download.
