Yes, the cloud seems to be crushing it, but according to Ellen Rubin, CEO and co-founder of ClearSky Data, as many as 50 percent of cloud customers have brought workloads back on-premise due to latency and performance issues in production applications for dispersed workforces. This makes it a pressing issue for dispersed teams, and threatens forward momentum.I spoke with Ellen about the problem, how latency affects businesses, and what CIOs can do to address the challenge.
BN: What is the difference between storage and network latency?
ER: Storage latency concerns the response time of physical storage media, such as disk drives, solid state devices (SSDs), non-volatile memory express (NVMe) solutions and more. Network latency is a measure of the response time of the networks used to reach that storage. As storage latencies have gone down, the network latencies associated with reaching cloud-scale data centers and remote cloud storage have become more significant. When enterprises work with high-performance business applications or attempt to increase their public cloud use, it’s often network latency issues that create roadblocks and hold those companies back.
BN: How does network latency affect your business?
ER: Network latency can hamstring cloud deployments, which are a top priority for many CIOs. While the public cloud market is predicted by Forrester to reach $160 billion by 2020, and the cloud offers vast economic benefits for enterprise IT, IDC reports that up to 50 percent of cloud customers have brought workloads back on premises due to network latency and performance issues.
This level of interference simply shouldn’t be acceptable to enterprise storage and cloud users. Just as a Netflix customer wouldn’t agree to wait hours to stream a movie, enterprises running apps using the public cloud should be free of lags and delays that can slow business and cause missed opportunities. Gartner recently released a manifesto for solving this problem by bringing data, content, resources and compute to the edge of networks -- using a content delivery model to augment the traditional data center and create an optimized user experience.
