My Customer wants to migrate their on-premise applications to cloud. Mostly we'll be using Lift and Shift approach using ASR. Customer's main objective is to reduce the infra cost.
Let us take an example of following
Current configuration of Appserver1 (in On-premise) is CPU- 2, Memory -32 GB, but avg CPU and memory utilization is 50% for a month.
When I create a Appserver1 in Azure, I really want to down size it.
But what is the proportion? For the cloud VM can I propose CPU-1 and Memory-16 GB?
Where can I find a standard formula to achieve this?
Thanks in advance
