Which service category focuses on container orchestration and management via API or web portal?

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

Answer: (B)

Container orchestration and management through APIs or a web portal are the hallmark of Container as a Service. This cloud model provides a managed platform to run, scale, and coordinate containerized applications, handling the container lifecycle, clustering, scheduling, networking, and storage via API calls or a web UI. It’s distinct from other service models: software delivered to end users (SaaS), a platform for building and deploying apps (PaaS) that isn’t primarily about orchestrating containers, or serverless functions (FaaS) that focus on executing individual code pieces on demand. In a CaaS setup, you can provision clusters, deploy containers, and automate operations through a control plane, which is exactly what the question describes.
