Hi,

We are currently in the process of onboarding legacy 2012R2 VM's to azure Arc for the ESU benefits initially.

Would you be able to provide some detail around exactly what data is sent from the Azure ARC agent, to azure, when going over a public internet endpoint (outbound 443) vs private link / private endpoint over express-route.

Have a security review soon, and am trying to find more information about this, so we can make an informed decision about whether private or public is more appropriate.

Is it all telemetry data, or is there some identifiable data sent over the link as well?

Many thanks.

    Hi @Paul Malham (NWIS - Core Services)

    Regarding

    Is it all telemetry data, or is there some identifiable data sent over the link as well?

    The data sent by Arc is generally telemetry information and authentication. But this information is transmitted over the communication channel of the agent. Information like computer name and network config can be transmitted over the internet, which is used for heartbeat and other related monitoring.
