Exam Professional-Cloud-Developer Topic 15 Question 23 Discussion

Your team is writing a backend application to implement the business logic for an interactive voice response (IVR) system that will support a payroll application. The IVR system has the following technical characteristics:
- Each customer phone call is associated with a unique IVR session.
- The IVR system creates a separate persistent gRPC connection to the
backend for each session.
- If the connection is interrupted, the IVR system establishes a new
connection, causing a slight latency for that call.
You need to determine which compute environment should be used to deploy the backend application. Using current call data, you determine that:
- Call duration ranges from 1 to 30 minutes.
- Calls are typically made during business hours.
- There are significant spikes of calls around certain known dates
(e.g., pay days), or when large payroll changes occur.
You want to minimize cost, effort, and operational overhead. Where should you deploy the backend application?
