Answer 1

Auto-scale based on Memory metrics for a Cloud Services is not currently supported.

To work around this problem, you can use Application Insights. Auto-Scale supports Application Insights as a Metrics Source and can scale the role instance count based on guest metric like ""Memory"". You have to configure Application Insights in your Cloud Service project package file (*.cspkg) and enable Azure Diagnostics extension on the service to implement this feat.

For more details on how to utilize a custom metric via Application Insights to configure Auto-Scale on Cloud Services, see Get started with auto scale by custom metric in Azure.
