Swap is virtual memory on disk that saves your VPS from crashing when RAM runs out. On low-cost servers, it’s an indispensable tool to avoid failures during short-term memory usage spikes. Setup is simple: create a file, enable it, and add it to autoload. But remember — it’s insurance, not a replacement for RAM.
Introduction
Modern VPSs are usually provisioned with enough RAM but often without swap (swap file or partition). This is a deliberate choice by providers who want you to quickly upgrade to a more expensive plan.

What is KVM?
KVM (Kernel-based Virtual Machine) is a virtualization technology built directly into the Linux kernel. KVM transforms the Linux kernel into a Type 1 hypervisor (bare-metal), allowing multiple virtual machines to run while leveraging hardware virtualization features of the CPU (Intel VT-x and AMD-V). KVM serves as a core component for many modern cloud platforms, including OpenStack and Red Hat OpenShift.
As part of Linux, KVM is a fully open-source solution, giving developers and system administrators enormous freedom and control over their infrastructure with zero licensing fees.

In today’s world, where digital technologies penetrate every sphere of life, the stable operation of IT infrastructure is not just a desirable condition — it is a critical necessity. Whether it’s a small website, a large online store, a mobile application, or an internal corporate system — any failure can lead to serious losses, reputational damage, and user dissatisfaction. This is where monitoring steps in.
What is Monitoring and Why Is It Important?
Monitoring in IT is the continuous collection, analysis, and visualization of data about the state and performance of infrastructure, applications, and services. Imagine you have a complex machine, like a car. To keep it running smoothly, you regularly check fuel level, oil, tire pressure. Monitoring serves the same purpose for servers, databases, networks, and applications.
