The virtualization of counting and the cost of cloud computing

Absrtact: Until recently, few IT industry vendors or analysts questioned the assumption that almost all types of virtualization offer fast, significant costs compared to only the computational savings in the physical world.

Server virtualization, especially in the early stages of such a VMware migration, is often the basis for a rigorous ROI/cost as part of the approval process, according to Ianson, Research systems and virtualization analyst IDC's software group

Higher or lower cost than expected is the main reason for VM files, slowing or stopping the migration of large virtual servers, according to James Tanton, the lead analyst for Forrester.

"People get real good impressions from server virtualization because the concept is simple and the payoff is something like 6 months because you can put a physical four server or multiple and save all the hardware costs," he said. "Desktop virtualization, especially, but cloud and streaming media applications and all other models are often subject to comparison." ”

Some of the cost surprises come from unrealistic expectations, from failure to a fit organization or budget to take on some of the greatest new technological advantages, Stanton said. But some surprises, too, come from even the smartest IT managers report to avoid or cloud the specific costs of virtualization projects, their bosses tend to be based on the system of automated vendor Apptio funded by a study of the Global Executive Council.

The study found that 64% of people think IT managers detailed tracking and virtualization cost analysis will be important this year, while 20% think it will be critical.

However, 48% per cent of respondents said they reported the cost/benefit cloud or virtualization as a single lump sum project. 25% of tracking costs, but say their numbers are not accurate enough to use the budget or audit. 20% do not report or as separate project cloud virtualization expenditures. 10% does not track costs. 80% said more detailed reports will be more important this year.

The biggest problem seems to be that most IT managers just don't know how to measure or report the results of a virtualization project, Stanton said. They are able to get away with that because some companies use it to track spending by specific departments, not to mention the deduction specifically for cloud or virtualization, according to Gellenschreck, Forrester's vice president and chief analyst.

Some use "showback"-the same thing as a deduction except that it only reports what kind of a business unit's virtual It usage costs would have been, in fact, not charging for it. Even taking into account the willingness to do robust financial analysis, there are some arguments about how, specifically, charging for computing services from hardware, storage and network abstraction.

There are four basic methods according to the analysis, from Apptio suggested by Andi, the Enterprise Management Association, who is currently the VP of Virtualization product marketing, former analyst and Gerod Carfantan, the VMware Solution development manager who blogs about, Cost and performance analysis in vcorneroffice.com:

Activity-based costing

This is essentially a consumption-type cost, in which the total cost of it is divided by transaction volume, number of servers, user or other standard measures of the specific business unit consumed by the IT workload.

If the analysis and tracking of this method is clear, even in virtualized environments, there is a way to take up unused capacity. What business unit pays for a dedicated application it seems that no one will use a virtual machine? The sheer cost per minute is attractive from an external service provider, but is only possible because other customers are paying ability when you do not use it.

Tiered Pricing

Branch offices do not require large storage, high-bandwidth or additional support that can be paid below the larger, more resource intensive operating unit "benchmark interest rate".

Those who handle their own most support can provide and manage their own server and management tasks, or they will be able to fall to the cost of it to enjoy discounts or discounts on the basis.

Service Infrastructure vs cost costs

A way for unused capacity accounts is to be independent of the "base" like WAN bandwidth or from applications, network access services to businesses or other units using the data center's real estate costs. Base business unit costs will remain relatively stable, and service costs will be based on different consumption.

The density of virtual servers, all the operations required for virtual infrastructure, licenses, servers, storage, bandwidth, it payroll, real estate, utilities and other infrastructure costs, can be cumulative and divided according to the number of Virtual server business unit needs.

Alternatively, the cost can be divided according to the application requirements. All the same elements go into the virtual server as it calculates the density, but the cost is divided according to the resources required by the particular application. The cost of a business unit is determined according to whether it is the only one using the application, or relative to the other business unit according to its usage ratio.
