I think most commenters are completely gleaning over the contrived systems which are embedded systems.
Sure, on higher performance systems you will be dealing with bigger demons such as cache and TLB performance depending on data size. But many embedded systems are performance limited for cost and power reasons. There is nothing here cloud will solve, nor anything else than more expensive NAND flashes, which require more power, and money. Hence why designing algorithms for critical data throughput are not as simple as using cloud or a filesystem.
