Additionally, RDP is optimized for Windows environments, and although it can work with other operating systems, the setup is more complex, and the user experience may not be as smooth. Full access to the remote machine also poses security risks if not properly configured, making robust security measures like firewalls and two-factor authentication essential.

What is RDS?

Remote Desktop Services (RDS) allows multiple users to share a single Windows server, providing access to applications and desktops. Unlike VDI, which provides individual virtual machines, RDS centralizes resources, making it more efficient and cost-effective. It’s ideal for environments where users need the same software, such as accounting or office applications, and reduces hardware expenses. RDS simplifies remote access by allowing users to connect from any device, with computing handled on the server. This centralized management also makes it easier for IT administrators to handle updates and security, offering a streamlined remote access solution.
