Eureka! New tech shrinks cloud computing’s carbon footprint

Grazed from InforWorld. Author: David Linthicum.

Want to reduce carbon emissions from cloud computing? A bunch of algorithms developed by computer scientists at Trinity College Dublin and IBM Research in Dublin can help reduce the carbon cost of cloud computing, the researchers claim. The algorithms, collectively called Stratus, can model a worldwide network of connected data centers and predict how best to use them to keep carbon emissions low. However, they also carry off the necessary computing and deliver the required data.

"For the simulation, the scientists modeled a scenario inspired by Amazon’s Elastic Compute Cloud (EC2) data center setup that incorporated three key variables: carbon emissions, cost of electricity, and the time needed for computation and data transfer on a network. Amazon EC2 has data centers in Ireland and the U.S. states of Virginia and California, so the experimental model placed data centers there too, and it used queries from 34 sources in different parts of Europe, Canada, and the United States as tests," according to the IEEE Sprectrum report on the research…

The researchers used the Stratus algorithms to optimize the workings of the network for any of several variables, including carbon emissions, cost of electricity, and the time needed for computation and data transfer on a network…
