  1. Toward Trusted Infrastructure for the Cloud Era

        At Synergy 2011 I made the case that the biggest barrier to the adoption of service-provider offered cloud services is the (understandable) lack of trust on the part of enterprise customers. Clouds are viewed as risky, and potentially insecure, at a time of rising cyber-crime, and there is also the issue of reliability. Here's a quick summary: I challenged the perception that enterprises are more vulnerable ...

  2. Xen and KVM – The Art of Accommodation

    thumb-XenPanda.jpg

        During all the fuss of Citrix Synergy last week, an event of pretty earth-shattering importance occurred in the open source world: all key Xen code was accepted into the Linux mainline kernel. This brings to an elegant close an enormous effort on the part of the xen.org and Linux communities, including very substantial contributions from Oracle, Citrix and other key Xen proponents, and continued ...

  3. Spring is Sprung

    I'm often asked what the Citrix answer is to VMware's glibly named "Open PaaS" platform for next-gen Enterprise apps, which it is developing from its various acquisitions including Spring. Whereas VMware's PaaS aspirations put it in direct competition with Red Hat's Makara & Jboss, IBM's WebSphere, Oracle's PaaS, to mention but a few, as well as for developer mind-share with language-specific platforms ...

  4. VMware customers – here’s a real cloud for you

    I hear from almost every Enterprise and service provider that vCloud is not what they want. Why? A significant concern is that it locks you into a single vendor cloud model that is utterly undifferentiated yet appallingly expensive, nickel and dime-ing you on a per-VM basis for every possible feature. Project Redwood - a massive undertaking from my friend the Sheriff ...

  5. The Rise of the Software Defined Network

    Today key players in the industry took a major step toward embracing an open cloud architecture. The Open Networking Foundation (ONF) has been established with the backing of many of the Great and Good in cloud computing: Broadcom, Brocade, Ciena, Cisco, Citrix, Dell, Deutsche Telekom, Ericsson, Facebook, Force10, Google, HP, IBM, Juniper Networks, Marvell, Microsoft, NEC, Netgear, NTT, Riverbed Technology, Verizon, VMware, and Yahoo! ...

  6. Far from the Madden Crowd

    For those with a handy QR Code Reader, read no further! Here's a beautiful piece of motel art for Brian that says it all: It must be that time of the month over at BrianMadden.com. That is, the time of the month when click-through rates for advertisers are pretty low because - let's face it - it's difficult for Brian come up with new stuff ...

  7. Carrion Picking in the Cloud

    The Register - by its own admission the carrion picker of the IT segment - is off on a rant about the Rackspace acquisition of Anso Labs, a boutique cloud foundry that collaborated with NASA to develop the Nebula compute cloud that is now the basis for the OpenStack Nova compute platform. Here are the unsubstantiated rather ridiculous pronouncements that el Reg makes: Rackspace's project leaders ...

  8. When a tree falls

    ...unobserved, in a remote forest, does it make a sound?". You can of course argue this till you're blue in the face, but I like the simple empirical approach: "No. Sound is a human experience of vibration, so no humans means no sound". Yesterday another redwood crashed to the ground without a sound. Nobody was paying attention to it. The news: ...

  9. Can They Match This?

    It's been a long time in the making, and the announcement is perhaps predictably short on detail. But it's fantastic to be able to publicly comment for the first time on our partnership with Amazon. Everyone knows that Amazon (AWS) operates the largest IaaS cloud. With a customer list that reads like the who's who of web brands, AWS knows more about ...

  10. Surprise! We do talk with storage vendors

    Edited post-hoc. A tad over the top. No offence intended Elias! I've been enjoying a quiet start to the year - twitter and blog-wise that is. I turned on tweetdeck for a bit, but to be honest, I really can't decipher @Beaker. Is it gibberish, or a secret code controlling an army of cloud-based "RT: @Beaker" bots? (#envy). (If you're ...
