Virtualized block device backing for virtualization containers

A system comprising:

• a host computer and a virtualization container instantiated on the host computer, wherein the virtualization container is configured to:
• present a virtual storage volume to a process executing in the virtualization container as a physical storage volume connected to the virtualization container, and
• transmit a data access request for the virtual storage volume to a storage service, separate from the host computer, to access data stored on a remote storage volume;
• and
• the storage service, configured to:
• receive the data access request,
• access the remote storage volume on a storage device, wherein the remote storage volume is associated with one or more read-only data snapshots, and
• process the data access request using at least one of the one or more read-only data snapshots.

A method comprising:

• presenting a virtual storage volume to a process as a physical storage volume, wherein the process is executing in a virtualization container;
• receiving a request for data in the virtual storage volume at a storage service separate from the virtualization container;
• accessing a remote storage volume on a storage device, wherein the remote storage volume is associated with one or more read-only data snapshots;
• and
• processing the request for data using the one or more read-only data snapshots.

A system comprising:

• a virtualization container comprising a storage driver, wherein the storage driver is configured to:
• present a virtual storage volume to a process executing in the virtualization container as a physical storage volume connected to the virtualization container, and
• transmit a data access request for the virtual storage volume to a storage service;
• and
• the storage service, wherein the storage service is configured to:
• receive the data access request,
• access the remote storage volume on a storage device, wherein the remote storage volume is associated with one or more read-only data snapshots, and
• process the data access request using at least one of the one or more read-only data snapshots.
