Virtual Desktop Infrastructure (VDI) enables organizations to deliver desktop environments from centralized cloud infrastructure, providing secure, scalable remote access to applications and data. Alibaba Cloud offers comprehensive VDI solutions through Elastic Desktop Service (EDS) and supporting infrastructure.

What is VDI?

VDI is a desktop virtualization technology that:

• Centralizes Desktops: Hosts desktop environments in the cloud
• Enables Remote Access: Provides secure remote access from any device
• Simplifies Management: Centralized management and updates
• Enhances Security: Data remains in secure cloud infrastructure
