Data Center Types
Data centers are not one-size-fits-all. Their design, scale, and purpose vary depending on the workloads they support — from AI training clusters with exascale accelerators to compact mobile units at the edge. Below is an overview of the primary data center types, highlighting their core purpose, defining characteristics, and example deployments.
