Today “Cloud computing” is one of the hottest catch word in IT domain. Every organization irrespective of size is jumping on the cloud computing bandwagon.
As with any new technology or process, cloud computing is also subject to misconceptions and myths. These myths probably arise from a poor understanding of the technology or the capabilities of the providers.
The best way to begin to appreciate the potential for cloud computing is through a definition of the term:
“Cloud computing is a model for enabling convenient, on_demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” – The National Institute of Standards and Technology, U.S. Department of Commerce; October, 2009(*1*)
Let us look at some of the myth associated with Cloud computing:
Myth 1: Cloud security and compliance is vulnerable.
Cloud computing security is no different than any secured network service. Cloud computing in itself does not introduce any new or unforeseen vulnerabilities or weaknesses.
Myth 2: All clouds scale on demand.
Not all cloud vendors have the resources or architecture to adequately scale applications and traffic on demand. While all try to maintain a certain number of extra resources to accommodate fluctuations, many cannot dynamically scale operations when demands exceed predicted thresholds.
Myth 3: Performance is worse in the cloud.
If the cloud infrastructure and applications are poorly managed and deployed, this might be true.But when properly configured, most users notice no difference when using cloud-based applications. In some cases, cloud computing provides noticeable improvements in performance as better provisioned machines with access to more resources can better handle more complex processes. The most significant potential bottleneck for cloud computing is access to the network itself.
Myth 4: Virtualization is equal to cloud computing.
Virtualization makes dynamic, scalable cloud computing possible, but does not constitute a cloud architecture on its own. Virtual machines deployed without intelligence or dynamic scalability can be nearly as inefficient and costly as physical resources they replace.
Myth 5: Cloud computing is only good for low end applications and software as a service.
Many vendors have jumped into the cloud computing market with simple software applications and declared themselves “cloud computing” experts. Cloud computing is the backbone on which businesses worldwide can perform thousands of transactions a second, transfer massive amounts of data across the globe. The most robust, secure, and scalable business applications available today can operate using cloud computing.
Myth 6: Cloud computing is less reliable than in-house systems.
Some of the most secure and reliable installations in the industry are cloud computing data centers. The best cloud computing centers are built from the ground up with multiple layers of redundant components,power, physical and cyber security measures.
Through this article, I have tried to bust some of the myth associated with cloud computing. Comments,suggestions and corrections are welcomed with open heart.
