Five common cloud computing fears

Don’t let fears about cloud computing prevent you from investigating the technology’s potential to reduce costs and open up space at your company. Below we explore five common concerns enterprises express about adopting cloud computing.

1. Proprietary exploitation. As Richard Stallman has suggested, cloud computing might be largely a marketing ploy to get data center managers to spend money on unproven technology. At this point, there is some question about whether the cloud can provide concrete benefits for its price tag. Open standards for clouds provide justification for not rejecting the cloud just yet, because they enable you to elect how to use the cloud. In charging for a narrow definition of cloud services, proprietary cloud service vendors often eliminate that flexibility.

2.Lack of transparency. Just as clouds are hard to see, your critical system resources stored within a cloud are also difficult to locate. It’s better to have a clunky, secure set of resources than a cheaper, airy one that might float into someone else’s hands; and public/private access rights to clouds are far from being established. Also, in the cloud ensuring compliance with existing security standards is difficult. There are no established standards for providers to enforce, and an attacker can modify sensitive data within one.

3. Wrestling cloud standards. If you’ve figured out solutions to the first two hurdles the struggle is not over. Other companies and users may have different ideas about how you should administer the cloud and formalize those ideas into standards. Now you’re noncompliant. But noncompliant with what? CTO of Amazon.com Werner Vogels doesn’t like the term cloud because it can mean so many different things. So before you decide to be a cloud for Halloween, check out the  study by the browser company Opera. Much of the Web has escaped standards compliance as well. So perhaps the problem is how standards are created rather than how they are enforced.

4. Integration into existing environment. You dodged the marketing trap, secured your resources, and committed to a cloud configuration that works for you. But now you’ll have to figure out how to integrate the cloud into your existing environment and how to manage it. Like cloud computing itself, this is mostly uncharted territory. But there are tools available to help you out such as  Kaavo and OpenQRM, and RightScale.

5.Loss of service.This month, concern about service outages came true for a handful of Google users who lost access to their outsourced Gmail accounts for nearly 24 hours. Unfortunately, having your services run elsewhere can leave you helpless to get them back.

The choice to employ cloud computing brings a lot of uncertainty, and some reason to be wary about the safety of your business’s resources in the cloud. And because cloud computing is emerging and largely unproven, it’s still up to you to determine whether the sky is falling or it’s just a passing cloud.

rPath offers Cloud Computing Adoption Model, webinar

Jake Sorofman, vice president of marketing for rPath, which provides technology for virtualizing software applications and managing cloud and virtualized environments, has offered a five step strategy on how to ease into cloud computing, and a webinar on the topic on October 2.  cloud

“Cloud Computing promises to reduce operating costs by increasing infrastructure utilization and reducing server sprawl; to reduce the cost of software consumption by allowing business lines to align cost with value received; and to dramatically improve business agility by compressing deployment cycles and time to value for application functionality,” Sorofman wrote. “It’s no surprise that cloud has attracted dozens of new entrants and forced incumbent vendors to articulate their own cloud strategy.”

For companies interested in moving their infrastructure into the clouds but aren’t sure where to begin, rPath’s Cloud Computing Adoption Model offers a set of clear guidelines to help move the process along.

Their model is a graduated, step by step approach for the adoption of cloud technologies that should help cut through the hype and lay out a clear game plan, incrementing toward cloud without putting projects, budgets and careers at risk, according to Sorofman.

Loosely modeled after the Capability Maturity Model (CMM) from the Software Engineering Institute (SEI) at Carnegie Mellon University, the Cloud Computing Adoption Model proposes five steps:

• Level 1: Virtualization. The first level of cloud adoption employs hypervisor-based infrastructure and application virtualization technologies for seamless portability of applications and shared server infrastructure.

• Level 2: Cloud Experimentation. Virtualization is taken to a cloud model, either internally or externally, using Amazon Elastic Compute Cloud (EC2) for compute capacity and as the reference architecture.

• Level 3: Cloud Foundations. Governance, controls, procedures, policies, and best practices begin to form around the development and deployment of cloud applications. Initially, Level 3 efforts focus on internal, non-mission critical applications.

• Level 4: Cloud Advancement. Governance foundations allow organizations to scale up the volume of cloud applications through broad-based deployments in the cloud.

• Level 5: Cloud Actualization. Dynamic workload balancing across multiple utility clouds. Applications are distributed based on cloud capacity, cost, proximity to user, and other criteria.

“At the end of the day, architectural innovations like cloud have transformational potential for enterprises. But the reality is that transformation can’t happen overnight — and it certainly can’t happen without a plan,” Sorofman wrote. “While the Cloud Computing Adoption Model may not represent a panacea for enterprise cloud computing, it does provide a context for thinking strategically about the pace, pattern and sequence of investments and returns that will set organizations on a pragmatic path to cloud.”

rPath is also hosting a webinar on this topic, “The Pragmatist’s Guide to Cloud Computing: A 5-Step Framework for Achieving the Strategic Value of Cloud Computing While Delivering Real ROI Along the Way,” on Thursday, October 23, 2008, at 11:00 a.m. Pacific time/2:00 p.m. Eastern time.

The webinar will feature guest speakers Jeff Barr, senior Amazon Web Services evangelist; Frank Gillett, vice president and principal analyst, Forrester Research; Jeff Schneider, CEO of MomentumSI; and Billy Marshall, founder and chief strategy officer, rPath. All registrants will receive a complimentary copy of “The rPath 5-Step Framework” along with the Forrester Research Paper, “Future View: The New Tech Ecosystems of Cloud, Cloud Services and Cloud Computing.” To register for the webinar, visit rPath’s website.
