App Services
The purpose of app service recommendations is to show savings on instances with rightsizing optimizations.
Recommending instances for rightsizing in app services simply requires finding a cheaper instance type from our price catalog that matches the current instance’s exact CPU and memory configuration. This could mean a newer generation instance type or any similar type.
The calculation for VM rightsizing in app services is the ((existing type rate (hourly) - suggested instance rate (hourly)) * 24) * 365, and we only show the first two decimal places.
