How do you match the size of the data center to the demand profile of smaller markets? Pre-fabricated data center designs are playing a key role, deploying server space in smaller, digestible chunks. This avoids the overbuilding that led to the data center glut during the dot-com boom, but also allows customers to expand gradually.
