Containersare the most appropriate cloud workload for running isolated applications with minimum resource overhead. Containers provide lightweight, isolated environments that share the host operating system, reducing resource consumption compared to virtual machines (VMs). They are ideal for microservices and applications requiring isolation without the overhead of a full VM.

From theCCSK v5.0 Study Guide, Domain 2 (Cloud Infrastructure and Platform Security), Section 2.5:

“Containers are lightweight, portable, and isolated environments that share the host OS kernel, making them highly efficient for running applications with minimal resource overhead. Unlike VMs, which require a full guest OS, containers provide application isolation with significantly lower resource demands.”

Option A (Containers) is the correct answer.

Option B (Function as a Service) is incorrect because FaaS is designed for event-driven, short-lived functions, not for running full applications.

Option C (AI Workloads) is incorrect because AI workloads are a category of tasks, not a specific workload type, and may run on VMs or containers.

Option D (Virtual Machines) is incorrect because VMs include a full guest OS, resulting in higher resource overhead compared to containers.
