Which two sources can be used to launch a new compute instance?

A custom image is a reusable image that contains the operating system and application software you need to create a new compute instance. By using a custom image, you can ensure that the instance starts with all the necessary configurations and software pre-installed, which simplifies the deployment process and provides consistency across instances. Custom images can be based on Oracle-provided images or can be created from existing compute instances.

Using a custom image enables you to easily replicate environments and ensure redundancy, as instances launched from the same image will have identical configurations and software installations, making management easier in large-scale environments. This is particularly useful in scenarios requiring multiple instances with similar setups, allowing for rapid scaling and deployment.

While bare metal instances and boot volumes are important components of Oracle Cloud Infrastructure, they are not sources from which you can directly launch a new compute instance in the same context as custom images. Object storage, on the other hand, is typically used for storing data rather than launching compute instances.
