Adoption of cloud computing has no doubt been slowed by worries about the security of those out-of-sight servers and resources. While reasonable, those worries have given way over time to acceptance and even optimism.
In this month's Modern Infrastructure cover story, TechTarget’s Trevor Jones writes about why security issues in cloud computing are not the impediment to adoption that they once were. In fact, some organizations are coming to the conclusion that their workloads run more securely in a public cloud than in an on-premises environment. Cloud service providers possess security expertise and experience at levels that aren’t as readily available on a typical IT staff, and certifications give confidence that providers can actually do all they claim to do.
The public cloud is not a risky place to do business, though its safeguards are different from those you've put in place to protect your own data center. These differences are most clearly seen when looking at the shared-responsibility model, which addresses many of the security issues in cloud computing. Users and providers must each do their part. Otherwise, the risks will become apparent, and cloud computing won't be what you need it to be.
This issue also looks at how a new wave of products in development brings memory and storage technologies closer together. Nonvolatile dual-inline memory modules, for example, combine the speed of memory with the persistent qualities of storage in some interesting ways. Also included is an article on how some IT shops that have adopted flash storage are simultaneously impressed and disappointed with the results. Costly flash products invariably improve performance, but they won't solve every problem or clear every bottleneck.Continue Reading
With these five quick tips, you'll be well versed in VMware VVOL advantages, requirements, components, management options and pre-implementation considerations. Continue Reading
A yottabyte is a measure of theoretical storage capacity and is 2 to the 80th power bytes, or, in decimal, approximately 1,000 zettabytes, a trillion terabytes or a million trillion megabytes. Continue Reading
Evaluate Storage performance characteristics Vendors & Products
Weigh the pros and cons of technologies, products and projects you are considering.
To make a business case for purchasing AFA storage, you must first understand what your applications need in terms of IOPS, latency and throughput. Continue Reading
All-flash arrays have virtually eliminated flash storage performance issues, for now. But applications and user expectations will eventually catch up. Innovations in flash technology -- such as nonvolatile memory express and storage-class memory (flash DIMM) -- promise to keep solid-state storage ahead of the curve, however. We discuss these technologies and more as we explore the current and future states of flash storage performance.
DevOps allows developers to rapidly create, develop, amend and deploy applications using Agile methodologies. DevOps resources, including storage, are consumed differently, though, taking more of a cloud-like approach.
Security and compliance concerns are big obstacles to public cloud storage adoption. Reliability, data movement and poor application performance, frequently from irregular spikes in network latency, are other important caveats. We provide tips on how to overcome these and other issues.Continue Reading
Security and compliance concerns are chief obstacles to public cloud storage adoption, as IT managers are hesitant to have their critical data reside outside the data center. Continue Reading
