What Is a Firewall  A firewall is a network security system that monitors, filters, and controls incoming and outgoing traffic based on predefined rules. In server virtualization, firewalls protect virtual machines (VMs) and the hypervisor from unauthorized access and malicious activity.  How a Firewall Works  Firewalls monitor network traffic and enforce rules to allow, block, […]

What is a Server Management Panel  Server management panels are web-based tools that simplify the administration of servers. They provide a graphical interface (GUI) for tasks that otherwise require command-line (CLI) knowledge. In virtualized environments, they help system administrators manage multiple virtual servers efficiently.  How a Server Management Panel Works  A server management panel connects

What is a Container   Containers are a lightweight form of virtualization that allows applications to run in isolated environments on the same operating system. Unlike traditional virtual machines (VMs), containers share the host system’s kernel, making them faster, more efficient, and easier to deploy.   How Containers Work   At their core, containers rely on operating system–level

What is an Operating System?  An operating system (OS) is the essential software that allows a computer to function and communicate with its hardware. It manages memory, storage, processing power, and devices, while also providing the interface that lets you run applications. Without an operating system, a computer would not be able to perform everyday

What is a Hypervisor?  A hypervisor enables virtualization by running multiple operating systems on a physical computer. Each system runs on its own virtual machine. Hypervisors maximize hardware utilization and provide secure isolation between workloads. Therefore, they are the foundation of modern IT, from corporate data centers to global cloud platforms.  How Hypervisors Operate  A
