I was reading an article the other day about the need for legacy organizations to transition to WebScale IT. Enterprise customers are trying to move to a more agile way of delivering services at the scale that companies like Google, Facebook, Amazon and Netflix have been able to achieve. There are several factors hindering this transition for a lot of customers in moving to webscale. There is no doubt of the benefits of this move and also the risk if not done right or soon.
There are three things to consider when moving IT to webscale: Performance, agility and efficiency. Each of these must be equally addressed and worked through.
