Interesting tidbit I learned today:
The main physical constraint for our firm’s expansion, and for large firms in the City of London in general, is access to electrical power. With all the computing power we’ve got in our London buildings – a couple of thousand employees, each with at least one workstation, many of them quite powerful, plus innumerable servers – and the air conditioning needed to keep them all cool, we suck huge amounts of power out of the grid. And now it’s apparently gotten to the point where we can’t take much more than we do today. It will be interesting to see whether we move out (we wouldn’t be the first bank to leave the City) or just shift the servers to an external data centre.
