Streaming conversion of virtual disk images for orchestration and management of heterogeneous computing resources

A computer system comprising:

• a source provider-specific computing resource;
• and
• a destination provider-specific computing resource comprising a destination agent configured to:
• receive a request to copy a virtual disk image from the source provider-specific computing resource to the destination provider-specific computing resource;
• and
• convert the virtual disk image from a source virtual disk format to a destination virtual disk format while copying the virtual disk image, the destination virtual disk format being different than the source virtual disk format, the source virtual disk format defining metadata at the end of the virtual disk image, wherein converting the virtual disk image comprises:
• predicting locations of data blocks within the virtual disk image based on structural characteristics of the source virtual disk format without accessing the metadata at the end of the virtual disk image;
• decoding the data blocks from the source virtual disk format to a raw virtual disk format while streaming the data blocks from the source provider-specific computing resource, wherein the data blocks are decoded based on the predicted locations of the data blocks within the virtual disk image;
• and
• encoding the data blocks from the raw virtual disk format to the destination virtual disk format while streaming the data blocks to the destination provider-specific computing resource.

A computer device comprising:

• a processor;
• and
• a non-transitory computer-readable medium storing instructions which, when executed by the processor, cause the processor to:
• receive a request to copy a virtual disk image from a source provider-specific computing resource to a destination provider-specific computing resource;
• and
• convert the virtual disk image from a source virtual disk format to a destination virtual disk format while copying the virtual disk image, the destination virtual disk format being different than the source virtual disk format, the source virtual disk format defining metadata at the end of the virtual disk image, wherein the instructions to convert the virtual disk image cause the processor to:
• predict locations of data blocks within the virtual disk image based on structural characteristics of the source virtual disk format without accessing the metadata at the end of the virtual disk image;
• decode the data blocks from the source virtual disk format to a raw virtual disk format while streaming the data blocks from the source provider-specific computing resource, wherein the data blocks are decoded based on the predicted locations of the data blocks within the virtual disk image;
• and
• encode the data blocks from the raw virtual disk format to the destination virtual disk format while streaming the data blocks to the destination provider-specific computing resource.
