One of the jobs of the Linux kernel—and all operating system kernels—is to manage the resources available to the system. When those resources get used up, what should it do? If the resource is RAM, there's not much choice. It's not feasible to take over the behavior of any piece of user software, understand what that software does, and make it more memory-efficient. Instead, the kernel has very little choice but to try to identify the software that is most responsible for using up the system's RAM and kill that process.

Chef is a Ruby based configuration management tool used to define infrastructure as code. This enables users to automate the management of many nodes and maintain consistency across those nodes.

A Chef client, installed on each node, is in charge of applying the recipe to its corresponding node. This guide will show you how to install and configure a Chef Server and Chef Workstation. We will also bootstrap a node to manage with Chef.

One of the main benefits of Linux systems is that they are known to be less prone to security vulnerabilities and exploits than other systems. Linux definitely gives users more flexibility and granular controls over its file systems' security permissions. This may imply that it's critical for Linux users to understand security permissions. That isn't necessarily true, but it's still wise for beginning users to understand the basics of Linux permissions.
