Virtual Desktop Infrastructure (VDI) enables users to remotely access desktop environments hosted on a centralized server. This process relies on three main components: virtual machines (VMs), a connection broker, and hypervisors.

Components of VDI

1. Virtual Machines (VMs): These are software-based desktops running on a host server. Each VM operates independently, creating isolated environments for users. This flexibility allows running systems like a Windows virtual machine online or even Linux in cloud computing environments.
2. Connection Broker: This software acts as a gateway, authenticating users and managing their access to virtual desktops. It also ensures that the appropriate desktop instance is assigned based on the user’s requirements.
3. Hypervisors: These tools partition physical servers into multiple VMs, allocating resources such as CPU, memory, and storage to each. Hypervisors power VDI by efficiently utilizing server capacity.

Flow of Virtual Desktop Delivery

• Users connect to the VDI system through a client device, initiating a request via the connection broker.
• The broker authenticates the user and assigns a specific VM tailored to their access needs.
• Hypervisors allocate server resources to ensure smooth operation, while the virtual desktop delivers real-time screen updates to the user’s device.

This seamless process makes VDI an ideal solution for remote work and enterprise environments. It bridges flexibility and security, offering scalable desktop virtualization in cloud computing.
