Which feature of Serverless offerings helps manage workload and billing?

• A. Budget thresholds
• B. Auto-scaling via operator
• C. Fixed invoice
• D. Mandatory on-prem deployment

Answer: (A)

Budget thresholds are the mechanism that ties cost control directly to how much workload you emit in a serverless setup. In serverless, you typically pay for what you use—invocations, duration, data transfer—so workloads can surge and push costs up quickly. Setting budget thresholds lets you cap spending and receive alerts (or take automated actions) when usage approaches or hits those limits. This keeps the system elastic for demand while preventing runaway costs, which is exactly what you need to manage both workload and billing.

Auto-scaling via an operator helps handle the amount of work happening, but it doesn’t inherently control how much you’ll pay. Fixed invoices don’t align with pay-per-use serverless pricing, and mandatory on‑prem deployment clashes with the serverless cloud model.
