VDI, or Virtual Desktop Infrastructure, in the context of a virtual machine (VM), refers to IT infrastructure that allows you to access enterprise computer systems from virtually any device via a VM.
Understanding VDI
VDI essentially hosts desktop environments on a central server, and users access these desktops remotely. It leverages virtual machines to achieve this. Let's break down the key components:
- Virtual Machines (VMs): Each user is typically assigned a virtual machine that serves as their desktop environment. This VM runs on a server in a data center.
- Centralized Server: The server hosts and manages all the virtual desktops.
- Remote Access: Users connect to their virtual desktop using a client application or web browser from their device (computer, smartphone, tablet, etc.).
How VDI Works with Virtual Machines
- Virtualization: The server uses virtualization technology to create and manage multiple virtual machines. Each VM represents a separate desktop environment.
- Desktop Image: A master desktop image containing the operating system, applications, and settings is created.
- Provisioning: When a user logs in, a VM is provisioned (or assigned from a pool) based on the master image.
- Remote Connection: The user's device connects to the VM over a network, and they interact with the desktop environment as if it were running locally.
- Centralized Management: All VMs are managed and maintained centrally, simplifying patching, updates, and security.
Benefits of VDI
- Accessibility: Access your desktop from any device, anywhere with an internet connection.
- Security: Data is stored centrally on the server, reducing the risk of data loss or theft if a device is lost or stolen.
- Centralized Management: IT can easily manage and update desktops from a central location.
- Cost Savings: Potentially lower hardware costs and reduced IT maintenance.
- Flexibility: Easily scale desktop resources up or down as needed. According to the provided information, this eliminates the need for your company to provide you with—and manage, repair, and replace—a physical machine.
Example Scenario
Imagine a company with employees who work remotely and in the office. With VDI, each employee can access their work desktop from their home computer, laptop, or even a tablet. All applications and data are stored securely on the company's server, and IT can easily manage and update everyone's desktop from a central location.
