CONSIDERING CLOUD APPLIANCES FOR PRIVATE CLOUD

DEPLOYMENTS

loud computing has the po-tential to deliver a number of very important benefits, including the ability to pro-

vision compute and storage resources on-demand. These

benefits take their most visible form in public clouds. However, for a variety of

reasons, some applications and workloads need to be run from behind the firewall.

For instance, the size of some data sets makes it im-practical to transport over the wire to a public cloud data center. Management may have security con-cerns about sensitive data being processed and archived in a facility outside of IT’s control. Some-times there are specialized hardware, architecture, networking, or storage requirements that cannot be accommodated in available public cloud environ-ments. In response, many companies are exploring private clouds.

Once a private cloud is being considered, there are two basic approaches to deployment: Build your own cloud or purchase a cloud appliance.

BUILD YOUR OWN CLOUDWith most enterprises already running their own compute, storage and network resources, one ap-proach to consider is redeploying these existing re-sources into a private cloud. In fact, given the last decade’s trend toward server consolidation, many of these servers may already be running a virtualiza-tion layer. Starting from this layer to build your own cloud, deploying infrastructure software from a sup-plier such as VMware, is therefore a logical consid-eration.

However, building a private cloud involves more than adding software layers to existing resources. “Today, enterprises and service providers that are interested in launching cloud computing services face the difficult task of integrating complex soft-ware and hardware components from multiple vendors. The resulting system could end up being expensive to build and hard to operate, minimizing the original motives and benefits of moving to this new model,” said Sheng Liang, founder and CEO of Cloud.com, a provider of open-source cloud com-puting software.

Unfortunately, many enterprises may not have the internal resources and expertise to take on this inte-gration workload.

THE OPEN SOURCE ALTERNATIVEIn addition, with proprietary technology comes the risk of vendor lock-in. In response, open-source al-ternatives have emerged. Rackspace CEO Lew Moorman said his company decided to use Open-Stack to open-source the software behind the cloud computing stack “because we believe a widely

adopted, open platform will drive standards.” As of OpenStack’s six-month anniversary, 53 companies had joined the community.

Drawbacks to adopting open source do exist, how-ever. For instance, OpenStack code base is still rela-tively young, and features such as supporting VM-ware hypervisors and live migration of instances are still in development.

In addition, IT personnel still need to download the project releases and integrate with the existing compute, storage and networking infrastructure. Although complexity can be removed by an open-source project, integration complexity still exists as components to the private cloud are provided by multiple hardware and software vendors.

This brings up another potential drawback: whom to call when a problem happens?

CLOUD APPLIANCESAnother approach to deploying a private cloud is through a cloud appliance. A cloud appliance is a rack of equipment delivered fully assembled and tested, with the software stack loaded and con-figured. When the appliance is connected to the power and network and turned on, it works.

It’s equivalent to buying a car today. Yes, you could assemble a “new” car from components already ly-ing around in your garage or pieces from existing cars. Some people relish this idea and no doubt could come up with quite a vehicle. However, for the mass market, driving a car already pre-assem-bled and tested right off the lot is the preferred op-tion.

As in the car example, a cloud appliance hides much of the hardware and software complexity required in integration and assembly. Instead, the appliance provider takes on this workload. And through replication and standardization, this pro-vider has the opportunity to travel up the learning curve. It’s an equivalent argument that supports the move to Software-as-a-Service. The team that does the same thing over and over again -- while developing supporting processes, test vectors, and underlying knowledge -- will be more efficient than another “do-it-yourself” team that’s building an equivalent cloud for the first time. The result is these efficiencies translate into reduced overall deploy-ment costs.

For example, computing solution provider AMAX offers its CloudMax private cloud appliance. This appliance integrates standard hardware compo-

nents and x86-based servers. By deploying a pre-integrated private cloud appliance, an IT team is saved time building its own. This enables an enter-prise to focus on delivering its core business value rather than building IT infrastructure. “The AMAX CloudMax appliance platform redefines the foun-dation of private cloud computing by eliminating the associated complexity and excessive costs with traditional private cloud deployments,” said Jean Shih, President at AMAX.

In addition, the AMAX CloudMax natively includes private cloud management capabilities from Plat-form Computing as part of its cloud software stack. “Platform Computing has been delivering large-scale distributed computing infrastructure software for cluster, grid and cloud environments for over 18 years,” says Jay Muelhoefer VP of Marketing for Platform Computing. “In fact, over 2000 customers - 9 out of the 10 largest global companies - total-ing more than 5 million CPUs are managed by Plat-form.”

Platform’s private cloud management offering, Platform ISF, is an integrated solution combining self-service, orchestration, and automation for het-erogeneous resource pools. As an open solution, Platform ISF eliminates lockin and provides compa-nies choice of hypervisor, physical provisioning, and external clouds in one consolidated management layer. Muelhoefer continues: “Cloud appliances are about simplifying the deployment and ongoing management without sacrificing power or future flexibility. Platform ISF supports fast time to value and choice, delivering the benefits of either the ap-pliance or ‘build your own’ model’.”

Getting back to the support question, a cloud appli-ance also offers a potential solution. The IT customer has only “one throat to choke” as the appliance vendor takes on the responsibility of supporting all the components utilized in building the appliance.

Cloud appliances have potential drawbacks. For instance, by definition new equipment is being pur-chased as part of the appliance, versus redeploy-ing existing resources. For this reason, a company might consider an appliance during a hardware refresh cycle.

In addition, as an appliance there are a limited num-ber of pre-configured models, and one size does not necessarily fit all workload requirements. For this reason, a solutions provider such as AMAX can also deliver a custom private cloud appliance based on its CloudMax offering. “Cloud is about improving IT responsiveness and increasing computing utilization and the AMAX CloudMax is empowering enterprises to accelerate private cloud adoptions and reduce IT management complexity,” adds Shih.

AN END TO PARTING WAYSDuring the early 1900s, there were hundreds of car manufacturers in the United States alone. By 1913, Henry Ford and his team developed the basic tech-niques of the assembly line and mass production, bringing standardization to the building of cars. The rest, as they say, is history.

Fast-forward to the present day evolution to cloud computing, and parallels can be drawn. It’s clear that companies are attempting to focus on core competencies, which for the most does not include building out IT infrastructure. And public cloud ven-dors are taking advantage of standardization to re-duce costs and offer higher levels of agility.

However, many workload requirements inhibit mov-ing data sets to public cloud environments, spawn-ing the deployment of private clouds. However, when an enterprise considers building a private cloud, it’s back in the discussion of building out IT infrastructure.

Cloud appliances offer a potential solution. By pre-integrating all components, IT simply plugs in and turns the power on. And after all, when buying a new car, you would prefer to turn the key and go, versus huddling hour upon hour reading the user manual. Why shouldn’t your private cloud deliver a similar experience?
