Virtual Desktop Infrastructure (VDI) is an IT solution that allows users to access enterprise computer systems from various devices, such as personal computers, smartphones, or tablets. Here are the key points about VDI:
- Virtualization Basics:
- Virtualization is the process of separating software (like an operating system or an application) from the hardware it runs on. It enables software to run on any device, freeing it from being tied to a specific physical machine.
- Virtual machines (VMs) are virtual computers created using this process. They exist as code and define their “hardware” (CPU, RAM, storage) through software.
- VMs share physical hardware resources (server) using a technology called a hypervisor. This allows VMs running different operating systems to coexist on the same server.
- What Is VDI?:
- VDI is a form of desktop virtualization where desktop environments (including operating systems, applications, and files) run within VMs hosted on a central server.
- End users access their virtual desktops over a network from devices like PCs, tablets, or thin clients.
- VDI eliminates the need for physical machines, as authorized users can securely access company servers, files, and apps from approved devices.
- Use Cases:
- VDI is commonly used to support remote and branch office workers, contractors, and partners.
- It enhances security by centralizing sensitive data and applications in highly secure data centers.
- Cost savings result from reduced hardware maintenance and management.
