Relay Service

The .NET-based Windows relay service communicates between the relay service in the cloud and the relay worker installed in the internal network. It's required to run at all times.

Recommendation: We recommend the Azure Relay Service as a relay service. It facilitates your hybrid applications by enabling you to securely expose services that reside within a corporate enterprise network to the public cloud. It does this without having to open a firewall connection and without requiring intrusive changes to the corporate network infrastructure. For further information, please see Azure Hybrid Connections.
