// Instance A compute host. The image used to launch the instance determines its operating system and other
// software. The shape specified during the launch process determines the number of CPUs and memory
// allocated to the instance.
// When you launch an instance, it is automatically attached to a virtual
// network interface card (VNIC), called the *primary VNIC*. The VNIC
// has a private IP address from the subnet's CIDR. You can either assign a
// private IP address of your choice or let Oracle automatically assign one.
// You can choose whether the instance has a public IP address. To retrieve the
// addresses, use the ListVnicAttachments
// operation to get the VNIC ID for the instance, and then call
// GetVnic with the VNIC ID.
// For more information, see
// Overview of the Compute Service (https://docs.cloud.oracle.com/iaas/Content/Compute/Concepts/computeoverview.htm).
// To use any of the API operations, you must be authorized in an IAM policy. If you're not authorized,
// talk to an administrator. If you're an administrator who needs to write policies to give users access, see
// Getting Started with Policies (https://docs.cloud.oracle.com/iaas/Content/Identity/Concepts/policygetstarted.htm).
// **Warning:** Oracle recommends that you avoid using any confidential information when you
// supply string values using the API.
