Two types of connectivity modes are available for the Azure Arc-enabled data services data controller:
- Directly Connected Mode – This is for organizations that maintain network connectivity to Azure. They are able to get a full Azure portal and Azure tooling experience in near real time when connected to Azure – for management of this DBaaS platform. Usage data, metrics, and logs are automatically sent to Azure. We used this connectivity mode in our lab for this paper.
- Indirectly Connected Mode – This is for organizations that have limited or no connectivity to Azure. DBAs use tools such as Azure Data Studio and Azure CLI (az) with the arc data extension to manage the data controller directly. This mode requires manual uploads of usage data, metrics, and logs to Azure using the Azure CLI.
