Question
Which of the following best describes a key advantage of
containerization over traditional virtual machines?Solution
Containers are a lightweight virtualization technology that packages applications and their dependencies together. Unlike traditional virtual machines (VMs), containers share the host operating system kernel. 1. Shared Kernel: By utilizing the host OS kernel, containers eliminate the overhead of running multiple OS instances. This feature allows them to start quickly and consume fewer resources compared to VMs. 2. Lightweight: Containers require significantly less memory and storage because they avoid duplicating the operating system. 3. Portability: Containers encapsulate all dependencies, enabling easy migration between development, testing, and production environments. The lightweight nature of containers, combined with their shared kernel architecture, makes them more efficient for modern, scalable applications, particularly in microservices architectures. Why Other Options Are Incorrect: • A) Direct access to hardware resources: This is a feature of VMs with a Type 1 hypervisor, not containers. Containers operate at the application layer, relying on the host OS. • B) Complete isolation from the host OS: Containers share the host OS kernel, which does not provide the same level of isolation as VMs. • D) No orchestration required: While containers are scalable, orchestration tools like Kubernetes are essential for managing large-scale containerized environments. • E) Elimination of VMM: Containers do not replace virtual machine monitors but coexist with them in some setups. VMs still use hypervisors to manage hardware resources.
