Accessing your files, programs, or computer from a different location using the internet. Like being able to use your home computer while you're at the office.
Remote access lets you open work files from your home computer or access your office computer while traveling.
Remote access is a capability rather than one product. These services enable remote access in different ways: WorkSpaces and Azure Virtual Desktop provide full managed virtual desktops; Google Cloud Workstations provides managed developer workstations accessed remotely; OCI Bastion provides secure, time-limited remote access to private compute resources (typically SSH/RDP via a bastion) without exposing them to the public internet.
