This section shows you how to create an SSH Key pair to be used to provision Oracle Cloud Services and later on to be able to authenticate via SSH connection from your SSH client.
Oracle Cloud services such as Oracle Java Cloud Service and Oracle Database Cloud – Database as a Service are built on top of infrastructure and functionality that are provided by Oracle Compute Cloud Service. When you create a service instance of one of these Oracle Cloud services, all the Oracle Compute virtual machines (VMs) required to support the service instance are provisioned and configured for you.
