Provisioned concurrency in Serverless offerings refers to?

• A. The amount of memory allocated per function
• B. The time to scale to zero
• C. The number of instances that can run simultaneously
• D. The maximum duration per invocation

Answer: (C)

Provisioned concurrency defines how many function instances are kept ready to run at the same time. In serverless, each invocation can use its own instance, so the total number of parallel executions is limited by this value. By pre-warming a certain number of instances, requests can be handled immediately without waiting for cold starts, reducing latency. This concept is about concurrent execution capacity, not about how much memory a function has, how quickly the platform scales to zero, or the maximum time an invocation can run.
