iperf3 is a command-line tool for assessing network performance. It allows you to measure bandwidth, latency, jitter, and packet loss between two endpoints. These measurements are useful for different scenarios like testing, checking the amount of available bandwidth, understanding the latency at peak hours, or planning a capacity for an

Operating a VPS means any and all network performance impacts the way your applications and websites behave. Just a split second of delay in transmitting data may result in slow page loads, service interruptions, and user dissatisfaction. A spike in traffic or undesirable bandwidth use puts the VPS in a

Kubernetes is the platform of choice for managing, scaling, and deploying containerized applications. The standard Kubernetes set-up (often referred to as "k8s") is complex and resource-intensive for smaller environments. Rancher Labs has developed k3s, a lightweight Kubernetes-compliant distribution. This guide will walk you through the steps to install

When managing a VPS, you often run the same commands in the same way every day. This could include updating packages, restarting web servers, or following system logs. These commands and processes are crucial. But the longer the command you have to type repeatedly, the longer it takes, and the

Disk I/O measures the speed of how quickly a server reads/writes to storage. On a Linux VPS, slow I/O will restrict applications, slow down response times to users, and ultimately create an unsatisfactory user experience. Dissecting, monitoring, and understanding these issue, will help to identify a bottleneck

ISO files contain an exact copy of a CD, DVD, or Blu-ray disc (and are compressed into a single file). In Linux, ISOs act as virtual discs, so they can be used like a disc without having to burn it onto physical media. ISOs are particularly useful for developers, system

A Virtual Private Server (VPS) needs constant monitoring to ensure smooth performance. When CPU, memory, or disk usage goes unchecked, even a small spike can slow down applications or cause downtime. Identifying the source of resource consumption is the first step toward fixing such issues. On Ubuntu VPS, two reliable

Apache Tomcat is the most widely used open-source Java application server developed by the Apache Software Foundation and built for deploying Java Servlets and JSPs. Tomcat is now a lightweight but highly extensible and detailed server for developing into a cross-cutting set of development applications, making it probably the best

When an application fails or slows down on a VPS, diagnosing it quickly is of utmost importance. strace is a Linux tool that traces system calls and signals made by a single process and shows the exact interaction with the operating system. It will show file operations, network activity, and

MariaDB is open source software that is a replacement for MySQL. Some of the features are ACID compliance, high performance, and scalability. Once installed, users can easily develop and manage databases as well as execute SQL queries. The reason you would install MariaDB on Ubuntu 24.04 VPS is to

Running a VPS gives you the freedom of control, but it also adds to your accountability regarding performance issues. One of the most common performance issues you can encounter is if a single process at some point in time has consumed too many CPU cycles. A high-CPU process can negatively

As a VPS admin, you often perform many of the same tasks frequently - updating applications, purging logs, performing backups, monitoring performance, etc.. Manually keeping track of all those tasks becomes burdensome and many can be done incorrectly. Automating these tasks allows all of the tasks to run at the

The Network File System is an efficient and powerful way to share files across Linux systems. Multiple clients can access the same files just like they were locally, which makes it perfect for environments such as Kubernetes, shared data servers, or development teams. This guide will show you how to

Issues related to a network interface on a VPS can disrupt critical workflows, block SSH access, slow your applications down, or cause your site to go offline. A simple mistake with a configuration or network interface can cause downtime, which may result in lost traffic, revenue, or customer trust. Quick

The “Too Many Open Files” error occurs on Linux when the operating system has reached its file descriptor limit. A file descriptor represents every open file, socket, or network connection on the system. When it hits the limit, the operating system denies file operations, leading running programs to error. Need
