Meeting the requirements for cloud data security entails applying existing security techniques and following sound security practices. To be effective, cloud data security depends on more than simply applying appropriate countermeasures. Taken collectively, countermeasures must comprise a resilient mosaic that protects data at rest as well as data in motion. While the use of encryption is a key component for cloud security, even the most robust encryption is pointless if the keys are exposed or […]

If you came here for the article with the title, “How Cloud Computing Helps a Business Grow”, unfortunately, it has been removed at the request of the publisher of the website from which it was obtained. Asking me to remove it was within their rights, but I believe it was a shortsighted decision based on old media ideas about the copyright “protection” of assets and the imagined potential loss of ad revenue. I am not […]
Want to know if your organization has the right characteristics and culture to successfully adopt cloud computing? I recently ran across a new cloud computing study that might provide the answer. “Our approach was to try to look into the future and determine what capabilities and kinds of organizations are necessary for a successful migration to the cloud,” co-author Arun Sundararajan told me. Sundararajan (associate professor of Information, Operations and Management Services at the NYU […]
Selecting a cloud computing provider is becoming increasingly complex. As cloud environments mature, many cloud providers attempt to differentiate themselves by focusing on specific aspects of their offerings, such as technology stacks or service-level agreements (SLAs). In short, not all cloud providers are created equal. At the same time, enterprises are beginning to rely on cloud providers for hosting mission-critical applications, which raises the stakes for selecting the right cloud service. So how do organizations […]
Cloud computing (Infrastructure-as-a-Service) has already proved its value to some businesses and specific applications. It provides a way to deploy and access massive amounts of IT resources, on demand, in real time. It drives better utilization of data center resources, reducing capital expenditures and operating expenses. Most important, it provides the scalability and agility to adapt to changing business needs. However, challenges remain with the Infrastructure-as-a-Service (IaaS) cloud computing deployment model. For enterprises that have […]
The three dominant cloud computing models — Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS) — are changing fast, as cloud providers reach up and down the stack to offer as close to a one-stop shop as possible. To understand how these cloud computing models are evolving and converging, it helps to know the history, said Jeffrey Kaplan, managing director of ThinkStrategies Inc., a consultancy in Wellesley, […]
High-performance computing (HPC) is no longer exclusive to large companies and governments with substantial scientific budgets. Why? The economics of HPC cloud computing bring these capabilities within reach of nearly any business. However, infrastructure and operations (I&O) professionals must realise that the level of ROI varies based on application design, behaviour and use case. Cloud economics let companies pay for capacity when and only when it is utilised, without requiring any upfront investment – essentially […]
2010 was the year “cloud computing” became colloquialized to just “cloud,” and everyone realized “cloud,” “SAAS” and all the other xAAS’s (PAAS, IAAS, DAAS) were all different implementations of the same idea — a set of computing services available online that can expand or contract according to need. Not all the confusion has been cleared up, of course. But seeing specific services offered by Amazon, Microsoft, Oracle, Citrix, VMware and a host of other companies […]
Cloud Adopters Embrace Cloud For Both Innovation and Legacy Optimization Once thought to be the answer to deployment options for just the SMB market, early cloud adopters proved otherwise. Stereotypes about industry, size of company, geographies, and roles no longer hold back adoption. Cloud adoption at all 4 layers of the cloud passed the tipping points in 2010 as a key business and technology strategy (see Figure 1). For 2011, we can expect users to: […]
One would think that for something with so much activity around it and so talked about that there would be a concrete definition of what cloud computing is. Instead, depending on who you ask, everyone seems to have their own definition of what cloud computing means. CA Technologies (NASDAQ: CA ) vice-president and country manager for Canada, Jimmy Fulton, summed it up best by saying “there hasn’t been a more ambiguous term in the IT […]
