Explanation

OS-level virtualization for distributed applications is described by three closely related terms: (C) container-based virtualization - the overarching category name for this virtualization approach where the host OS kernel is shared among isolated user-space instances; (E) application containerization - the practice of packaging an application and its dependencies into a container so it runs consistently across environments; and (F) containerization - the general term for the process and methodology of using containers (e.g., Docker, LXC). All three terms refer to the same paradigm where containers share a single host OS kernel (rather than emulating full hardware like a hypervisor), making them lightweight and well-suited for distributed applications. The distractors - 'shared kernel' (A), 'virtualized networking' (B), 'container stack' (D), and 'container networking' (G) - are either component concepts within container infrastructure or generic descriptors, not defining terms for the virtualization method itself.
