What is Cloud Computing, Anyway?

Irving Wladasky-Berger, chairman emeritus of IBM's Academy of Technology, recently posted a comprehensive overview on Cloud Computing titled "What is Cloud Computing, Anyway?" on his blog.  Irving also wrote about this subject in an earlier post, "The Promise and Reality of Cloud Computing."  Excerpts below:

Iwb

"Cloud computing is the kind of wide-ranging initiative that different people can look at from their own point of view and come up with their own, somewhat different definitions.  This is not surprising in the early stages of such a comprehensive initiative.  When the Internet first broke into the wider world in the mid 1990s, you similarly heard lots of different opinions on what it was and what it would be good for. In reading through the assorted cloud definitions, five key themes keep coming up.

  1. Well designed consumer and business services
  2. The evolution of the Internet
  3. Massive Scalability
  4. Well engineered cloud delivery centers
  5. How relevant is cloud computing to most companies?"

Very worthwhile reading.

Greenmonk: Data centers as energy exporters, not energy sinks!

Tom Raftery at Greenmonk recently published a thoughtful post titled Data Centers as energy exporters, not energy sinks!  Tom's post includes quotes from Intel's Nick Knupffer and Steve Sams at IBM on progress being made to reduce heat at the chip level.

Tom reports . . . "However, according to the video below, which I found on YouTube, IBM are going way further than I had thought about. They announced their Hydro-Cluster Power 575 series super computers in April. They plan to allow data centers to capture the heat from the servers and export it as hot water for swimming pools, cooking, hot showers, etc. This is how all servers should be plumbed."

Lessons Learned from IBM's Big Green Initiative

GreenerComputing's David Metcalfe has just published a "lessons learned" story on what IBM has learned since announcing its Project Big Green initiative in May 2007 and its Project Big Green 2.0 announcements last month.

The article reports . . . "After 12 months of customer dialogue IBM's Big Green initiative expanded from a focus on hardware energy efficiency in the data centre to a consulting-lead offering for corporate energy efficiency and carbon management. Through its customer outreach IBM learnt six lessons about the commercialization of Green IT:

1. Exploit IT's information management role.
2. Hitch Green IT to data centre refurbishment projects.
3. Tackle corporate energy efficiency and emissions.
4. Differentiate offerings by industry and country.
5. Plan for slow customer adoption.
6. Prepare for investment barriers to IT energy efficiency."

Read the whole story here.
