Understanding the ins and outs of cloud computing can be a fairly complicated task. For example, deciphering the difference between local applications utilizing a cloud platform vs. Web-based Software-as-a-Service (SaaS) implementations. Both configurations have the ability to achieve similar results for the end user, but their processes are inherently different from each other. That being said, a couple recent surveys have shown that most people are downright baffled by cloud technologies.
Last week, Citrix announced the results of a cloud survey conducted by Wakefield Research. The study aimed to discover what people actually think about cloud computing. 1,006 Americans were asked some basic questions regarding cloud technologies. With 40 percent of respondents saying that working "in the buff" was the the cloud's greatest advantage, the survey displayed a situation that is both hopeless and humorous.
Of the participants, 54 percent said they hardly use or never use cloud technologies, even though 95 percent claimed to use services like Gmail, Facebook and YouTube. 22 percent admitted they pretended to know how the cloud works, and were bold enough to do so during a job interview.
29 percent believed cloud technologies had something to do with the weather and 51 percent thought that changes in weather could affect cloud computing. That last statistic has some potential to be true, like when Amazon suffered an outage due to severe storms at one of their datacenters.
Given the results, one could potentially argue that the Citrix survey was possibly flawed. Maybe the questions were too vague or the participants might have been improperly selected. But yesterday, EurActive reported on the results of a similar, but larger survey on the other side of the Atlantic. Nonprofit trade association Business Software Alliance (BSA) facilitated the study.
Out of 4,000 European computer users polled, only 24 percent said they access cloud applications. 65 percent were unfamiliar with cloud computing and some admitted they "never heard the name."
Usage varied quite a bit between countries. On the higher end of the spectrum, respondents from Greece and Romania reported 39 percent adoption of cloud technologies. On the other hand, only 9 percent of those surveyed from Poland said they were familiar with cloud applications.
These surveys reveal that a surprising number of people are unfamiliar with cloud technologies and the benefits they provide. To combat this issue, the European Commission is set to release a cloud computing strategy for the European Union. This includes fixing regulatory concerns and promoting off-site data storage services, like Amazon's recently announced Glacier service. Similarly, the US office of Management and Budget has issued a cloud first IT strategy.
The ever-growing complexity of scientific and engineering problems continues to pose new computational challenges. Thus, we present a novel federation model that enables end-users with the ability to aggregate heterogeneous resource scale problems. The feasibility of this federation model has been proven, in the context of the UberCloud HPC Experiment, by gathering the most comprehensive information to date on the effects of pillars on microfluid channel flow.
Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).
Frank Ding, engineering analysis & technical computing manager at Simpson Strong-Tie, discussed the advantages of utilizing the cloud for occasional scientific computing, identified the obstacles to doing so, and proposed workarounds to some of those obstacles.
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
04/02/2012 | AMD | Developers today are just beginning to explore the potential of heterogeneous computing, but the potential for this new paradigm is huge. This brief article reviews how the technology might impact a range of application development areas, including client experiences and cloud-based data management. As platforms like OpenCL continue to evolve, the benefits of heterogeneous computing will become even more accessible. Use this quick article to jump-start your own thinking on heterogeneous computing.
