Introduction

As we approach 2026, Linux serves as the foundation of the internet. It remains the dominant OS for VPS, dedicated hosting, cloud hosting platforms, and enterprise data center environments for performance, reliability, and flexibility. These advantages also mean that Linux is an attractive target for attackers. Today, attackers leverage AI-based botnets, automated attack scripts, and vulnerability scanners that continuously scan Linux servers for outdated software, open and/or misconfigured ports, poor authentication, and unpatched vulnerabilities. Your Linux server could completely compromise with a missed package version or one overlooked setting.

In light of the increased threats to your Linux server, the act of securing a Linux server is no longer a “once in a while” or straightforward task. You must devote sustained attention on an ongoing basis, advancing the server administrator role to one associated with monitoring in a proactive way, and configuring a hyper-hardened security posture. You, the server administrator, are now the guardian of Uptime, Customer Data, & Host Environment Longevity. This guide identifies the most applicable Linux server security practices for 2026 and how VPS Owners and hosting teams can put these practices into action and build a strong and resilient infrastructure.

If you’re running a website from a Linux-based server, whether it is via shared hosting, VPS hosting, or even a cloud server, it is imperative to ensure that your server has enough memory (RAM) so that everything operates cleanly. Memory is what your server uses to run applications and process tasks; basically, memory runs everything that powers your website. As memory becomes full or overloaded, your website will ultimately slow down, become unresponsive, or completely crash. For businesses that depend on uptime and speed, that is the last thing that you need.

The good news is that checking memory usage on a Linux server isn’t hard. Even if you don’t consider yourself “techy”, there are quick and simple ways to get an overall idea of how much memory your server is using and what is occupying space. In this blog, I present six simple methods that get you familiar with memory usage on your Linux hosting server. These methods are helpful especially if you are running WordPress on a VPS, are managing clients on a reseller hosting account, or hosting applications in a dedicated Linux environment.

As a Web Hosting service provider, we do get many clients posing queries on which hosting platform to choose, Windows or Linux? Which platform is most preferred? And more. But the truth is, both are great in their own way and choosing between both Linux and Windows platform, completely depends on your website requirements.
