Is your enterprise cloud ready for the big leagues? Start with Triple A.

So your organization wants to be more agile—aspiring to spin up new test environments in minutes, speed development processes, and scale infrastructure with ease. Your reflex is to move applications to public cloud to gain agility, but that isn’t always the right option. Sure, some cloud-native applications are well suited to public cloud, but other enterprise applications are not. The cost of recoding, refactoring, and building resiliency into those applications before migration can be prohibitive. Continue Reading…

What do you do when a virtual machine becomes a noisy neighbor?

Virtualized application performanceThe #1 pain point in the data center is poor performance. That’s what we found from our study of 1,000 data center professionals, who every day watch virtual machines (VM) conflict with databases, slow each other down, and eat up hours spent fine-tuning storage and tackling trouble tickets.

A huge contributor to this performance pain is what’s called “the noisy neighbor problem” — a VM consuming too many resources at the expense of others.

The problem stems from LUNs, the conventional storage groups made up of dozens or even hundreds of VMs. When one of them gets noisy, demanding more than its share of performance reserves, it slows down its neighbors and throws the entire LUN into chaos.

Because they’re built on that LUN architecture, most storage environments running VMs face this challenge. Stopping these rogue VMs is difficult because they’re nearly invisible to scrutiny and correction.

Here’s how you put the issue to rest and guarantee every VM’s performance: isolation. By eliminating the LUN and giving every VM its own neighborhood through VM-aware storage, you can more precisely control the resources apps can demand. Continue Reading…
