Cloud Connectivity 

Connectivity from the edge to the cloud is essential and there are many ways to securely connect to the cloud. Typical infrastructure includes mutual authentication, which is essentially two-way authentication between the Edge Gateway and the cloud, at the same time using a certificate. Once the secure connection is established, the communication typically happens using one of the asynchronous protocols such as WebSockets, binary protocols using Event Hub, MQTT, STOMP, and HTTP 2. In addition to the connectivity,  typically an Edge Manager manages all the connected Edge devices to provide dashboards for operations capability.
