Question 4What underlying architecture do containers leverage?1 pointA hypervisorGuest operating systemsThe host kernelA cloud control plane

Breaking Down the Problem

1. Identify the key components of container technology.
2. Understand the options provided: hypervisor, guest operating systems, host kernel, cloud control plane.
3. Determine which option correctly represents the architecture that containers leverage.

Relevant Concepts

• Containers are a method of virtualization at the OS level, which allows multiple isolated applications to run on a single host operating system.
• Unlike traditional virtualization that relies on hypervisors and guest OSs, containers share the host OS's kernel.

Analysis and Detail

1. Hypervisor: This component is used in traditional virtual machines (VMs) to manage and allocate resources among multiple operating systems. Containers do not use hypervisors.
2. Guest Operating Systems: Containers do not require separate guest OS instances as they operate using the same OS kernel.
3. Host Kernel: This is the core of the host operating system that containers use to function. Containers share the host's kernel for process management, memory, and I/O.
4. Cloud Control Plane: This refers to services that manage cloud resources and does not specifically pertain to container architecture.

Verify and Summarize

After evaluating the options, it is clear that containers operate by utilizing the host's kernel rather than relying on hypervisors or guest operating systems.

Final Answer

The host kernel is the underlying architecture that containers leverage.
