Which statement best describes On-Demand instances in cloud computing?

• A. They require long-term commitment
• B. They can be spun up in seconds and disposed of as needed
• C. They are always the cheapest option
• D. They guarantee uninterrupted availability

Answer: (B)

On-Demand instances are about provisioning capacity exactly when you need it, with no upfront commitment and pay-as-you-go pricing. They can be created in seconds and terminated as soon as you’re done, which is ideal for variable workloads, testing, or sudden spikes in demand. This flexibility is what makes them the most straightforward choice for scenarios where you don’t want to commit long-term. They aren’t guaranteed to be the cheapest option, since other models (like reserved or spot instances) can offer lower costs for steady or flexible utilization. They also don’t guarantee uninterrupted availability, as capacity and maintenance events can affect continuity.
