Deployment

A cloud engineer is preparing an operating expense report to guide the purchase of various cloud billing models for virtual machine instances. The chosen billing model must satisfy the following requirements:

  • The instance must not be ephemeral.
  • The instance is expected to have a minimum life cycle of five years.
  • The software license is charged based on the physical CPU count.

Which of the following billing models best meets these requirements?

Explanation

A dedicated host provides a physical server reserved exclusively for one customer's use, meaning the instances running on it are persistent (not ephemeral) and suited for long-term, multi-year deployments. Because the underlying physical hardware is dedicated, it allows organizations to track and apply software licenses based on physical CPU sockets or cores (bring-your-own-license model), which is required for many enterprise software licensing agreements. Spot instances are inherently ephemeral and can be reclaimed at any time, making them unsuitable for a five-year life cycle. Pay-as-you-go pricing is typically used for flexible, short-term, on-demand workloads without guarantees of dedicated physical hardware for license counting. Resource metering is simply a mechanism for measuring usage, not a purchasing or billing model itself.
