Why do cloud providers use dedicated hardware for network and storage processing but not large enterprises for their private cloud?


Answer: Large cloud providers use dedicated hardware called data processing unit (DPU) to support multi-tenancy and isolation in hardware vs. hypervisor, improve performance through offload, own and control the entire infrastructure stack, free up cores to generate more revenue, and scale to support a large number of tenants and workloads. Large enterprises don't have similar needs except for a few applications that require high performance, low latency, and scale. Moreover, enterprises want to reduce their investment in building and managing data centers.
