As the second law of thermodynamics tells us, all things trend toward chaos and this is no less true with a virtual environment. Sprawl can have a real security impact, and it takes discipline and planning to control sprawl — discipline and planning that won’t occur without someone from the security team actively monitoring the problem and formulating strategies for how to address the issue. Virtualization has been one of the most rapidly and widely […]

We can shop on our phones and read magazines on our tablets. But playing high-end video games on a mobile device has been out of the question. That might be about to change. OnLive, a Silicon Valley start-up, on Thursday plans to release software that will let people play the richest, most graphically intense games on Apple’s iPhone and iPad, as well as on Amazon’s Kindle Fire and other devices based on Google’s Android software. […]
One of the main reasons for deploying desktop virtualization is the security advantages it can provide, such as keeping sensitive data off the endpoint, according to Citrix. And Citrix is practicing what it preaches at its Ft. Lauderdale, Fla., headquarters where employees, for example, use the Citrix virtualization product Citrix Receiver for smartphones and tablets. Citrix Receiver brings full-fledged desktop apps to smartphones and tablets “It’s required to access some systems such as SAP,” says […]
Social networking sites like Facebook and Twitter encourage sharing of personal information. How does this change the nature of personal privacy? Trust is fundamental since it forms the basis upon which personal and commercial transactions take place. However trust and privacy are in conflict since knowing who you are dealing with is essential to trust. So how can identity, privacy and trust in the Cloud be reconciled? Privacy The internet and social networking sites like […]
So tell me, what’s a Hadoop when it’s at home? Some kind of dance? Not so much. Think of it as a file system for distributed computing and storage. Because that’s what it is. What’s a file system for distributed computing and storage when it’s at home? Let me take you back to big data. What’s big data? You know all that stuff you’ve got that fits in nice relational databases? Yes. Well, it’s that […]
Historically, business telecommunications has been a highly exclusive club of well-financed service providers who have been highly dependent upon business models that are pegged to over-subscription, product bundling and oligopolistic market control. Telecommunications infrastructure has been a world of very expensive, highly proprietary equipment and telecom applications such as voicemail, conferencing, three-way calling and caller ID have been developed exclusively within the doors of the large service providers who intended to put them in the […]
Over the past 24 months, the interest in cloud computing – a general term for software deployed through hosted, managed services and software-as-a-service (SaaS) models – has continued to grow. As a result, the movement of more business applications into the cloud is becoming more prevalent. This popularity is made clear when you consider the recent report from ARC Advisory Group, which revealed the supply chain management market grew 7 per cent in the last […]
More and more enterprise IT shops – as they get comfortable with virtualization practices in their own private clouds – are considering a jump to the public cloud. But before making that leap, consider these pieces of advice from those that have already jumped. 1. Make sure your provider has VM-specific security “Hypervisors were never really designed to be running in a public environment,” says Beth Cohen, senior cloud architect for Cloud Technology Partners, a […]
Researchers from North Carolina State University and IBM have developed a new, experimental technique to better protect sensitive information in cloud computing – without significantly affecting the system’s overall performance. Under the cloud-computing paradigm, the computational power and storage of multiple computers is pooled, and can be shared by multiple users. Hypervisors are programs that create the virtual workspace that allows different operating systems to run in isolation from one another – even though each […]
In a new survey, access-management vendor Imprivata forecasts that health care will move ahead of other industries in the adoption of desktop virtualization. Imprivata, a provider of access-management tools, has released the results of a survey showing health care poised to take the lead in desktop virtualization adoption in the next 12 months. For the report called “2011 Virtualization Trends in Healthcare,” researchers interviewed 477 IT managers in multiple industries, including health care and financial […]
