Data Centre Economies of Scale

bytes

At the Waters:Power09, last week, Bob Giffords argued there are three ‘gravitational’ forces leading to the mega data centres and cloud computing.

  • There’s too much data to move, it needs to stay where its created.
  • Intra system & total latency is still a problem, and hence systems are best co-located with the data.
  • He argues that energy management is a gravitational issue.

Some insights into managing the cloud

Dave Cliff, Professor of Computer Sci at Bristol spoke to Waters Power:09 in Canary Wharf yesterday. It is clear from many sources that IT is changing and he examined some of these changes. He woke me up by quoting Carlota Perez¬† who argues that there are five transformational changes since the industrial revolution, Steam, Railways, Electricity, internal combustion and IT. She also argues that the adoption and maturity cycles are similar, and Cliff argues that “money’s out of IT now”. Her book is called “Technological Revolutions and Finance Capital:The Dynamics of Bubbles and Golden Ages”, which gives on an idea of where she’s coming from. Cliff also pointed his audience at Nick Carr’s “The Big Switch”, another pundit that argues that IT is done! …

What will the Cloud do?

I was pointed at the Eucalyptus project, an open-source software infrastructure for implementing “cloud computing” on clusters, by a colleague and decided I needed to check out Amazon first. Several colleagues have given me this advice but have the University really written an open source grid platform conforming to Amazon’s EC2 APIs. if so, it’s a fascinating example of the speed of commoditisation. …

Billing for Clouds

When considering the some of the issues related to building private clouds, the “Usage to Billing” problem was raised and I was reminded of Emlyn Pagden’s Blueprint, “The Utility Model PII” 2003. I had been consulting with a mid sized European Investment Bank, and discussed the architectural problem with them, and Emlyn. Its a while since I have read Emlyn’s paper, but he took the architectural decomposition,  …

Talking about Cloud Computing

The current technical state of systems, storage and networking and specifically the cost of broad band networking has created a tipping point. Over the last 10 years, organisations and people have been learning to build new distributed computing server complexes. It may be too late to copy the leaders, but certain design criteria and the regulatory constraints may mean that there is a slower commercial adoption cycle. Other factors are making the adoption of cloud compelling and this blog article looks at some of them.  …

Back in Berlin

I returned to Berlin for a business meeting, travelled via LCY and had a good night out with the French team. For various reasons, Zoo station has always been a place of mystery to me, since reading the eponymous book.  …

Will CPU trading enable an FX market??

I met with Roger Day, Sun’s Engineering Director responsible for building Sun’s Utility Grid. We had a long conversation. I was eager to explore how one makes the outputs of the grid homogeneous, since the homogeneity of commodity is one of its axiomatic qualities. He asked me what I thought of the idea of an exchange. I replied that my view is that if we can create a primary market, and it looks like we can, a secondary market will follow. I wonder though if people will look to exchange Solaris CPU/hours for AIX or even Windows CPU/hours. Will we have a cycle FX market?. …
