Components for Launching Instances
These components are required to launch a compute instance:
Tenancy
The root compartment that contains all of your organization's compartments and cloud resources. The Service Enclave administrator creates the tenancy in which compartments are created. A tenancy administrator creates compartments in a tenancy where the compute resources are created. You must have a tenancy to have compartments where instances are launched.
Compartment
A collection of related resources that are only accessible by certain groups that have been given permission by an administrator in your organization. Compute instances are created in compartments. All compartments exist in a tenancy, which is the root compartment.
Virtual Cloud Network (VCN)
A virtual version of a traditional network—including subnets, route tables, and gateways—on which your compute instance runs. At least one cloud network must be set up by a Compute Enclave administrator before you launch compute instances.
Key Pair
If the image that is used to launch the instance is configured to require Secure Shell (SSH) for authentication, then you need an SSH key pair before launching the instance. This requirement applies to instances launched from images provided with Private Cloud Appliance and by most UNIX type images. If the image is configured to use passwords instead, you need the password instead of the key pair.
Image
A template of a virtual hard drive that determines the operating system and other software for a compute instance. You can also launch compute instances using these images:
-
Images provided with Oracle Private Cloud Appliance
-
Custom images created from other instances
-
Import your own image
For more information about images, see Compute Images in the Oracle Private Cloud Appliance User Guide.
Shape
A template that determines the number of CPUs, amount of memory, and other resources allocated to a newly created compute instance. You choose the most appropriate shape when you launch a compute instance.
