What is the purpose of "cgroups" (control groups) in the Linux kernel?
Correct! Well done.
Incorrect.
The correct answer is A) Cgroups allow the kernel to limit, account for, and isolate the resource usage (CPU, memory, disk I/O, network, etc.) of a collection of processes, forming the other major kernel mechanism (alongside namespaces) underlying container resource management
Correct Answer
Cgroups allow the kernel to limit, account for, and isolate the resource usage (CPU, memory, disk I/O, network, etc.) of a collection of processes, forming the other major kernel mechanism (alongside namespaces) underlying container resource management
Cgroups let administrators (or container runtimes) constrain how much CPU, memory, or I/O a group of processes can consume, preventing one set of processes from starving others of resources — a critical feature for multi-tenant systems and containers.
