Leymans Cloud Economics Musings

This whole cloud thing. Does it work as a sustainable financial concept, or is there a tipping point that slides us back towatds a more traditional hosting model? Firstly, we must recognise that not all clouds are the same, have different financial models and different purposes. This post doesn't profess to be the fountain of all knowledge on cloud financial models, rather a musing on a potential for there to be an effectual glass ceiling or not where the model of clouds tips back in favour of a more traditional hosting architecture. Long term average costs of productivity are assisted by a scale out and long term strategy - all heading in the direction of reducing the average short term costs by applying an economy of scale model to … [Read more...]

Building A Swimming Pool In Your Datacentre

As the vSpecialist Blog has a standing remit to report on cool (forgive the pun) technology in the virtualised and enterprise spaces, here is another example of the kind of innovative technology that's invading datacentres. Got cooling problems? Just build a swimming pool in your datacentre, then chuck in your servers and let them cool themselves in the water. Think I'm joking? No, it's not (quite) April Fools, but a new piece of tech. from Green Revolution Cooling. Of course, it's not quite as simple as that - but almost it is. First reaction - of course not. Second reaction - actually that would work! Simply doing a few changes to your hardware (or building new OEM hardware to use this technology) could allow this to be retro-fitted … [Read more...]

vSpecialist Little Gems

Occasionally, I come acoss some features of an OS or technology that aren't widely known, used or talked about that I think are really cool and worth investigating further. They could be (and often are) from all spectrums of the IT spehere - from Mac OS to Windows, from cloud platforms to hosting infrastructure, from web applications to desktop widgets. I plan to write these up in a series of mini-posts to give you, the reader, some inspiration to look deeper into the technology you use, to discover more hidden gems or features you may not have discovered. Little Gems published so far: [catlist name=little-gems] … [Read more...]

Is Your Cloud Really A Cloud?

Lots is being made about cloud technology. Cloud as a vision, cloud as a technology set, cloud as a service provider, cloud as a direction for computing. But is cloud really cloud for most of us? Cloud providers in the adoption stage are at a crossroads for technology deployment. The direction they take at this first crossroads often dictates if they take a true road to being a cloud provider, or if they take a path towards an alternative solution that simply provides enterprise a virtualisation solution with a self-service element. … [Read more...]

503 Errors and vCloud Director

In our lab set-up, I have been experimenting with vCloud Director configurations and high availability for vCloud Director cells - and more specifically what happens when the vCenters behind vCloud resources dissapear or have availability issues - then reconnect. If a vCenter hosting the resources crashes and is subsequently restored, there may be odd or unexplained error codes from vCloud Director - specifically: Unexpected Status Code: 503 ...was seen a lot - when creating or deploying vApps within an Organisation that is backed by the resources managed by the vCenter that crashed. Interestingly, some vCloud functions continued to work whilst the continuity of vCenter was interupted, but this was due to the other resilient vCloud … [Read more...]

Poore the vSoup

Between recent visits to the San Francisco area I was lucky enough to join Chris Dearden (@chrisdearden), Christian Mohn (@h0bbel) and Ed Czerwin (@eczerwin) for a recording of the vSoup podcast. In truth, it was 3rd time lucky as being 8 (or 9) hours behind and on a fairly manic schedule didn't lend itself too well to planning anything with anybody. I have to say that it was great fun and I'd love to do it again sometime when the subject of conversation won't be abnormally large shower heads. At some point in the proceedings I did manage to slip in a plug to the vSpecialist VCDX practice event - that we've yet to organise properly - but what with work commitments and new jobs it's taken a back seat for a few weeks. We might have to see … [Read more...]
