Virtualisation: Opinions

  • Apple: Great new products, but secrecy as a religion

    Apple CEO Tim Cook, along with a few friends, Monday performed the annual Apple Worldwide Developers Conference keynote. The show must go on, even without Steve Jobs, and it sure did go on -- two well-packed hours of Apple mantra and mania. They did not talk about what I was watching for, but it turned out OK anyway.

  • The future holds much promise

    Last year, IT budgets declined by 10 per cent to 20 per cent, depending on who you believe. Jobs were lost. And the pool of vendors is constantly shrinking, given the tsunami of bankruptcies and mergers over the past few years. (Adios, Nortel.)

  • A primer on cloudbursting

    The term "cloudbursting" was coined by Amazon Web Services evangelist Jeff Barr to describe the use of cloud computing to deal with overflow requests, such as those that occur during seasonal rushes to online retail sites.

  • Cloud computing. More than blue sky thinking

    Looming on the horizon are the nimbus, cirrus, stratus and cumulus that threaten to deliver us cloud computing imminently. Promising an end to most of the challenges and frustrations of IT systems as we know them, the concept of cloud computing is thundering through the business community to become one of the most talked about and revered subjects of the day.

  • Storing your data in their cloud

    Although it may seem like your computing life is all e-mail and browsing, computer users still create files, documents, spreadsheets, boring presentations and all manner of other stored information. Which brings me to the question: Where do you store your data? And are you ready to store your data online in a service hosted by a third party provider?

  • Peering behind the cloud

    Cloud computing is at its peak of hype. In fact, it's probably about to jump the shark. Savvy enterprise IT managers know there's little reason to embrace cloud this early in its development.

  • What Gartner didn't say about virtualization

    Gartner released its annual "Top 10 Strategic Technologies for 2009" and pride of place goes to virtualization, put right at the top of the list. More surprising, perhaps, is the fact that Gartner placed Cloud Computing directly below virtualization in the second spot.

  • Reinventing storage virtualization

    The initial approach to storage virtualization, which has been around for years, was to address it in the storage-area network because the SAN sat between the storage and servers, and would cause the least disruption to these systems. However, after nearly a decade, this approach has not taken off while server virtualization has become widely accepted. What needs to be changed to make storage virtualization as ubiquitous as server virtualization?

  • Playing ahead of the curve

    Every now and again a technology comes along that, to some extent, sells itself. In recent years, the best example has been server virtualisation and many in the channel have had a great time closing deals based on this “no-brainer”. As usual in this industry, every man and his dog jumps quickly on the gravy train and skills that were recently seen as a market differentiator become commoditised before you can say ‘hypervisor’.

  • The challenge of securing virtualization operations

    I have been very interested in virtualization security since early 2004 and it now seems like it has become a mainstream topic. Most of the focus however is on securing the technology of virtualization (the hypervisor) and providing virtualized security (usually as virtual appliances). My focus nowadays is more on the operational impact of virtualized infrastructure and by extension the impact on security operations. After all, security controls (technology) are essential but without operational controls (people) they are not sufficient. So what is the operational impact of virtualization?

  • VMotion and FCoE: A match made in admin heaven

    In a recent review, I consolidated FC and Ethernet networks using FCoE (fibre channel over Ethernet) and Cisco's new Nexus 5000 switch. As the review showed, the combination merged the two transport protocols easily, allowing FC frames to channel through a 10G connection without giving up features or performance.

  • Preview: VMware Fusion 2 Beta 2

    Virtualization on the Mac has never had it so good. There are several options available for running almost any x86-based operating system as a VM under Mac OS X, including Parallels, VMware Fusion, and VirtualBox. If you like the fact that Macs are less prone to problems, viruses, and spyware, but you simply have to run a few Windows applications, it's a great time to be alive.
