Private Clouds: Tough To Build With Today's Tech

Missing standards, scant automation, and weak management tools make this next step beyond server virtualization a challenge.

Let's not spend time debating whether fully virtualized data centers will become the norm. They will, and sooner than you may think. You have bigger challenges than how soon you can get 50% or 75% or 99% of your servers virtualized.

Almost half of companies buy into the broader vision of a private cloud, finds our InformationWeek 2011 Virtualization Management Survey of 396 business technology pros. By private cloud, we mean an internal network that combines compute, storage, and other data center resources with high virtualization, hardware integration, automation, monitoring, and orchestration. But getting there with today's technology will be tough. We'll look at the range of problems IT faces, such as multivendor environments, limited automation, and still-emerging technology and standards.

Standards are scarce indeed, making every purchasing decision dicey. You must understand how every component interacts with every other component, but since extensive server virtualization has increased operational complexity, this can be an extraordinarily difficult thing to get your arms around. IT teams looking to conventional network and systems management products for help are finding that these expensive tools are inadequate to the task at hand.

"The only savings realized from virtualization is fewer physical servers," says one respondent to our survey. "Costs have increased via more expensive servers with bigger I/O and more memory, added cost of the hypervisor, and a much more difficult time to resolve problems when they occur."

VMware is still the go-to vendor when IT organizations talk enterprise-class server virtualization.Only 36% of the respondents to our survey have secondary hypervisors in use at their companies. But Citrix and Microsoft are closing the gap.

Asked to rate the importance of a dozen virtualization features, survey respondents cited high availability as No. 1 and price a very close second. Both Microsoft Hyper-V R2 and Citrix XenServer offer high-availability features with a reasonable price tag. VMware also offers high availability in its entry-level packages, except that it doesn't bundle features like Distributed Resource Scheduler, for machine load balancing, with its low-cost vSphere Essentials, making it an incomplete offering.

Other highly valued factors include live virtual machine migration (available from all major vendors), fault tolerance, load balancing, and virtual switching/networking. Citrix and Microsoft recently cozied up to Marathon Technologies to provide fault tolerance for their platforms.

The features VMware offers that the others don't--like Storage DRS, which load balances data store I/O, and Storage vMotion--land in last place in our survey. VMware's decision this year to increase its price beyond a certain virtual memory allocation was met with such howls from customers that VMware raised the limit--but that move only delays a price increase that could drive companies to consider alternatives. If it's bells and whistles like Storage DRS and Storage vMotion that VMware expects to justify higher licensing costs, our survey respondents aren't buying it. "With steady improvements to Hyper-V and Xen, and Oracle's integration of Virtual Iron into their VM product, we have lots of alternatives to consider," says one respondent.

However, mixing production hypervisors almost guarantees that companies won't have a unified, automated disaster recovery scheme. And it can require some deep expertise if you want one policy to govern all of your systems, a common goal.

What percentage of your company's production servers do you expect to have virtualized by the end of next year?

Some good information here. Microsoft is holding some webcasts on this issue in November and December (focused on MS products).

Always use an authorized Cisco Reseller like http://PCIT.us VOIP GBIC used Proliant servers

Current IT practice, tough to manage without today's technology / Private cloud.

re: Private Clouds: Tough To Build With Today's Tech
Its easy to build a Private cloud with today's tech, I have built several Private / Hybrid Clouds
so I know this to be true. Its getting people to change that's hard.

ToutVirtual (www.toutvirtual.com) today and for a number of years (since 2005) has been providing Management & Policy-based Automation for physical & virtual environments from a single agnostic web console. This enables organisations to reduce complexity within there datacenter/s and delivers automated management on-demand.

The VirtualIQ Pro solution from ToutVirtual provides a single pane of glass enabling organisations to future-proof there IT investments.

It doesn't matter whether you build a public cloud, a private cloud, whether that be with a single hypervisor or multiple hypervisors or even fully virtualised or both physical and virtual, VirtualIQ Pro is the only solution that delivers.

ToutVirtual have created there own methodology called "Crawl-Walk-Run" providing organisations a simplified approach to Automation. This simplified approach provides datacenter managers/virtualisation administrators the ability to ensure improved application availability which was the top driver within the survey compiled within the above article.

The solution works out of the box, is cost effective and reduces the multiple layers of complexity within any datacenter. Why not visit the ToutVirtual website and download your free trial so you can see for yourself.
