How are my VMs and Applications billed?

How Denvr bills for compute instances —Virtual Machines (VMs) and Applications (Apps)—that are stopped or idle. The details below reflect current platform behavior

What happens when I stop a Virtual Machine or Applications from the Denvr console?

When you stop a VM or App via the Denvr console:

• All compute resources and ephemeral storage are deallocated.

• Persisted storage continues to incur charges until explicitly removed by the user.

---

Does stopping a Virtual Machine or Application from inside the OS (e.g., using shutdown) stop billing?

No - stopping from within the guest OS does not deallocate compute resources. The instance remains in an active, billable state. You must stop it using the Denvr console or APIs to halt compute billing.

What are the differences in billing between VMs and Apps when stopped?

Feature	Virtual Machines (VMs)	Applications (Apps)
Stoppable from Console	Yes	Yes
Compute charges while stopped	No	No
Root storage	Persistent root disk (billed)	Ephemeral root_FS (not billed)
Filesystem storage	Billed until data is removed	Billed until data is removed
Storage billed while stopped	Yes (root disk and filesystems)	Yes (filesystems only)
Storage deletion behavior	Root disk deleted on VM delete; filesystems persist	Filesystems persist after App delete

---

What storage types are billed when a Virtual Machine is stopped?

Storage Type	Billed While Running	Billed While Stopped	Deleted When
Root Disk	Yes	Yes	When the VM is deleted
Filesystems	Yes	Yes	When user deletes data inside filesystem
Ephemeral Storage	No	No	Discarded on stop

---

What storage types are billed when an Application is stopped?

Storage Type	Billed While Running	Billed While Stopped	Deleted When
Root_FS (ephemeral)	Included in compute	Not applicable	Discarded on stop
Filesystems	Yes	Yes	When user deletes data inside filesystem
Ephemeral Storage	No	No	Discarded on stop

---

If I delete a Virtual Machine or Application, will all storage charges stop?

Not necessarily.

• For VMs, deleting the instance also deletes the root disk, but any attached filesystems persist and continue to incur charges unless the user deletes the data within them.

• For Apps, the ephemeral root_FS is discarded automatically, but filesystems persist and continue to be billed until emptied.

---

How do I stop being billed for persisted storage?

You must delete the data within any mounted filesystems. Simply deleting the VM or App will not remove or unbill filesystem storage.

---

Can I snapshot or back up my data?

Not at this time. Denvr does not provide a user-accessible way to snapshot or back up data. If data is deleted, it cannot be recovered.

Although the platform performs internal storage replication for fault tolerance within a failure domain, this is not user-controlled and does not affect billing.

---

Where can I monitor my usage and costs?

Use the Cost and Usage → Cost Explorer screen in the Denvr console to track your current charges.

Note: Reserved compute charges are billed manually and are not yet visible in Cost Explorer. Full cost integration is planned in a future release.

Summary

• Use the Denvr console to stop VMs or Apps in order to deallocate compute and ephemeral storage.

• Persisted storage is the only component billed while an instance is stopped.

• VM root disks are deleted when the VM is deleted.

• Filesystems persist after instance deletion and must be manually cleared to stop billing.

• No backup or snapshot capability is currently available to users.
