Each cloud provider has its own set of user images, instances, resources, allocations, and options. Cloud provider resources are based on availability and reservations are required.

The CyVerse Cloud – Marana cloud provider is available for all users as of July 2017. This is the general-purpose default provider. This provider runs an updated, more resilient OpenStack version and configuration, and supports a new function called instance shelve. Similar to stopping an instance, shelving an instance shuts down an instance but does not consume time allocation. More information about shelved instances is available at Suspending, Stopping, Rebooting, Resuming, Starting, Moving, and Deleting Instances.

Other providers in your Providers list may be available, depending on the providers to which you have been granted access. For example, if you will be participating in a workshop or course, you may also have been granted access to the iPlant Cloud – Workshop provider. The iPlant Cloud – Austin provider is reserved for image developers, tool developers, and prepublication preparation; its allocation is granted by separate science committee, and is based on availability and the nature of the project.

You may request access to this and other cloud providers by completing the information requested below. Allocation increases are based on availability, fair share, and the user's request.

Changing or selecting your default provider

The providers in your list depend on the providers to which you have been granted access. You also can enable or disable the image provider on a per-image basis.
