Multi cloud asynchronous active/active transactional storage for availability

摘要

A method, apparatus, and system for storing data at a multi cloud-based storage system is disclosed. The operations comprise: receiving a data block at a first cloud of a multi cloud-based storage system for storage, the multi cloud-based storage system comprising a first number (n) of clouds; generating the first number (n) of coded blocks at the first cloud based on the data block, wherein the data block is recoverable from any second number (k) out of the first number (n) of coded blocks, and wherein the second number (k) is greater than 1 and less than the first number (n); and distributing, by the first cloud, the first number (n) of coded blocks to the first number (n) of clouds of the multi cloud-based storage system, each of the clouds including the first cloud receiving a respective one of the first number (n) of coded blocks for storage.
