What is RDP and why is it important for Azure VMs?
RDP, or Remote Desktop Protocol, is a proprietary protocol developed by Microsoft that enables users to connect to another computer over a network connection. For Azure Virtual Machines (VMs), RDP is crucial as it provides a graphical interface, allowing users to manage their VMs as if they were directly in front of them. This functionality is particularly valuable for tasks such as system configuration, administration, and troubleshooting.
Using RDP facilitates easier access to the VM’s desktop, allowing users to install software, transfer files, and perform configurations that would be difficult or impossible through command-line interfaces. Being able to visually interact with the VM makes it more manageable for both administrators and developers, enhancing productivity and efficiency when working in the Azure environment.
