You would be wrong to think that a company like Microsoft with billions in profits doesn’t care about data center construction costs. The company, which has previously been accustomed to spending $500 million and up on new facilities, will now try to reduce construction costs on new facilities to $250 million.
Microsoft will be able to meet its target while still maintaining the power and speed needed because of advances in efficiency and scalable technology. New data centers will consist of a wall-less open-air structure full of server-packed containers. They’ll be “containerized” so to speak.
As more computing juice is needed, more containers can simply be shipped and added to the mix. This ease of expandability significantly cuts down on up-front costs.
