Google has many large facilities that are definitely not shipping containers. You can do this for caching sites but it doesn't really work all that well from a cooling efficiency POV. In 2009 when they were building shipping containers their PUE was as high as 1.22 which is essentially not that much better than traditional raised floor and air conditioners. Their modern DCS are not built like this. Instead they have hot aisle and cold aisles. They call their cold aisles hot huts. So you essentially trade off time to market for PUE. In a large compute region the higher PUE of the shipping container approach is going to limit how many servers you can put in that location because power to a particular site is often a limiting factor. Also not everywhere do you have access to water from the Columbia river.
