PCaaS (PC as a Service) is an IT procurement and operating model where companies rent computer hardware — PCs, laptops, or workstations — together with the software, management, maintenance, and support around it, for a fixed monthly fee.
Instead of buying or leasing devices and then managing them in-house, companies hand off the entire hardware lifecycle — from provisioning to security to proper disposal — to an external provider. That turns capital expenditure (CapEx) into predictable operating expenses (OpEx).
