Geoff is considering whether to deploy on-premises infrastructure or cloud-hosted infrastructure. His most important requirements in order are: Ease of scalability, Management overhead, Cost. If Geoff wants to run a containerized service that can handle very large loads, what model should he select?

An infrastructure-as-a-service (IaaS) cloud-hosted model where a third-party provider focuses on scalability and administration of a containerization service will meet Geoff's needs. When scaling from low to very large load is a common event, the ability to grow or shrink in a cloud environment can also provide significant cost savings over paying for an on-premises option that can handle the full scaling event. Software as a service (SaaS) and platform as a service (PaaS) provide full applications or platforms, not containerization environments.
