Abstract: Methods, systems, apparatuses, and computer program products are provided that enable immediate access to data associated with a source blob. The foregoing is achieved by creating a copy-on-read blob based on the source blob and a link blob based on the copy-on-read blob for each virtual machine to be deployed. When creating the copy-on-read blob, the source blob is not copied. Instead, data from the source blob is copied to the copy-on-read blob upon request by a virtual machine. Subsequent requests for that data are retrieved from the copy-on-read blob. Each link blob stores write data provided by its corresponding virtual machine. When a virtual machine requests data, its corresponding link blob is checked for the data. If the data is not stored therein, the copy-on-read blob is checked for the data. If the copy-on-read blob does not store the data, the data is retrieved from the source blob.

Abstract: A cloud service provider supports immutable data on its servers and the immutable data is movable across multiple access tiers, in which each access tier affects access performance and cost. In typical implementations, the immutable data may be blobs of unstructured data such as text or binary data, multimedia, among other data types, which are organized into containers that provide a directory for user interaction with the data. Policies are applied at the container-level which regulates user interactions with the containers and the container's blobs. A policy can, for example, prohibit modification and deletion of blobs within a container until a policy's set retention period expires. After expiration of the retention period, the container and that container's blobs may be deleted, but blob modification may still be prohibited. A user interface is configured to enable a user to move containers to other access tiers while the container maintains its policy.

The consumer may then take actions accordingly based on the level of authenticity of the received digital asset.
