The industry has long worried that cloud computing cannot deliver the performance required for critical enterprise applications. For example, the very notion of multiple compute instances or multiple applications sharing the same infrastructure has meant that service providers cannot guarantee service level agreements for response times. This has held many companies back from making the jump to the cloud. These performance bottlenecks are indicated in Figure 1. Multiple applications or virtual machines simply drive too much storage traffic to traditional disks, which cannot keep up with demands. Figure 1: Multiple applications or compute instances drive storage and I/O performance bottlenecks Moving data and applications to cloud infrastructures comes with a twofold challenge: maintain high system performance while data size continues to grow and constantly keep ...
