Which service offers virtualization of container engines, management of containers, applications and clusters through a web portal or API?

• A. SaaS
• B. PaaS
• C. Container as a Service (CaaS)
• D. IaaS

Answer: (C)

Container as a Service is about giving you a managed environment for containers, where the container engines are virtualized and you can handle containers, applications, and clusters through a web portal or API. It provides the control plane for provisioning, deploying, scaling, and coordinating containers and their clusters without needing to manage the underlying hosts yourself. This lets you interact with Kubernetes or other orchestrators via a dashboard or programmatic calls, focusing on building and running apps rather than maintaining infrastructure.

SaaS delivers ready-to-use software over the web, not the container infrastructure. IaaS offers raw virtual machines and networking, letting you install and manage your own software but not specifically provide container orchestration and management as a service. PaaS provides a platform to deploy applications, often abstracting away the runtime details, but it doesn’t center on managing container engines and clusters through a portal or API in the same way as CaaS.
