Which two aspects of Serverless computing are critical to understand from a cost perspective?

• A. Data transfer out and memory optimization
• B. Code deployment and monitoring
• C. Storage duration and durability
• D. Code execution and autoscaling

Answer: (D)

The cost in serverless is driven by how long your function runs and how many concurrent executions the platform handles as demand grows. When code executes, you’re billed for the duration of that execution and the memory (or resources) allocated to it, so understanding runtime performance and chosen memory size directly affects cost. Autoscaling determines how many function instances run in parallel under load; more concurrent executions can increase total billed compute time even if individual invocations are short, making concurrency behavior a major cost lever. So focusing on how long code runs and how autoscaling changes the number of simultaneous executions gives you the clearest handle on governing serverless costs. Data transfer, storage durability, deployment, and monitoring matter for other reasons, but they’re not the primary cost drivers in the typical serverless billing model.
