Connecting to an Oracle Cloud instance using PuTTY involves establishing a secure and encrypted connection between your local computer and a virtual server stored on the Oracle Cloud. PuTTY, a widely-used SSH and Telnet client for Windows, serves as the tool to create this connection, offering a secure method to access and manage your Oracle Cloud instance.
