Private and public clouds have many elements in common, including high degrees of virtualization and automation and a usage-based service model. But that doesn’t mean an enterprise application will run equally well in either environment. Most legacy applications are better off staying in your data center. At the same time, the public cloud should be the first place you consider deploying new applications. Here’s why.

Traditional enterprise applications are better suited to the private cloud. These applications are typically built in a silo-centric fashion and are dependent on the hardware, particularly homegrown applications. Don’t let virtualization fool you; even if the applications are virtualized, they’re still silo-centric. The only difference is it’s now virtual hardware. You’re still working on the outdated model of one application, one OS…

Six months ago, IBM launched PureSystems, new-wave mainframes which combine RISC and Intel servers and promise a new and simpler way to develop enterprise applications. But since that initial fanfare,we have heard almost nothing about the supposedly revolutionary servers.

That doesn’t mean nothing is happening, though, says IBM senior server consultant IBM Tikiri Wanduragala. He grabbed TechWeekEurope last month, to tell us that PureSystems is a response to commodity cloud computing. It might take time to mature, but it is on track. The meeting took place in the run-up to the announcement of new PureSystems tailored for Big Data analytics…

Like many other companies, processor manufacturer Intel Corp. is having to evolve its information security focus to meet the changes underway in the technology landscape—particularly with the rapid growth of mobile devices and applications and the rise in cloud computing services.

"We realize the importance of detective controls and building out our security business intelligence capabilities to scale and meet future business objectives around computing," says Alan Ross, senior principal engineer at Intel. "We must have the ability to aggregate, correlate and even visualize many billions of events per day. This type of scale requires investment in many areas."…

Security is one of the main factors preventing companies from switching to cloud computing, particularly cloud storage, as they are worried about how well protected their data will be. But according to Google’s enterprise director of security, the cloud is probably a lot more secure than the in-house systems most firms are currently using.

Speaking to ZDNet, Eran Feigenbaum acknowledged that the exact level of security provided would largely depend on the type of organisation in question and who the cloud service provider was. However, he insisted that in most cases greater security would be offered in the cloud…

Two major trends in enterprise computing this year show increasing overlap: big data processing and open source cloud adoption. To Hortonworks, the software company behind open source Apache Hadoop, the connection makes sense. Enterprise customers want the ability to spin up a cluster on demand and quickly process massive amounts of data, said Jim Walker, director of product marketing at Hortonworks, in an interview at OSCON in July. The cloud provides this kind of access by its ability to scale and handle computing tasks elastically.

The open source cloud offers the additional benefit of low-cost deployment and extra plugability you won’t get with a proprietary cloud infrastructure. All three major open source IaaS platforms — OpenStack, CloudStack and Eucalyptus — have made much progress this year in testing Hadoop deployments on their stacks. And Eucalyptus is working on full integration with the platform…
