The majority of corporate IT workloads are now running off-premises for the first time, according to data released Thursday [1].
This shift marks a fundamental change in how businesses manage their digital infrastructure. As companies move away from internal data centers, they rely more heavily on third-party providers to handle the energy and cooling requirements of modern computing.
The transition is largely driven by the evolving physical requirements of server hardware. According to the Uptime Institute, the average rack power density has crested above 11 kW [1] for the first time. This increase is occurring as server fleets are gradually replaced with more powerful hardware [1].
Many corporate facilities were not designed to handle such high power densities. When the energy needs of new hardware exceed the capacity of existing on-site cooling and power systems, companies are forced to migrate their workloads to external facilities, such as colocation centers or cloud providers, that can support these demands [1].
Uptime Institute said "most corporate IT is now off-premises for the first time" [1]. The trend reflects a broader industrial movement toward specialized infrastructure that can sustain the high-density power needs of current enterprise technology [1].
As older hardware is retired, the gap between what a standard corporate office can support and what modern servers require continues to widen. This has accelerated the exit from traditional on-premises IT environments across global corporate facilities [1].
“The majority of corporate IT workloads are now running off-premises for the first time.”
The migration to off-premises IT suggests that the physical limitations of traditional office architecture are becoming a bottleneck for technological growth. As power density requirements increase, the cost and complexity of retrofitting old corporate buildings to support modern servers outweigh the benefits of owning the hardware on-site, cementing the dominance of specialized data center providers.
