Hardware as a Service (HaaS), in a managed services context, is a procurement process similar to licensing. Generally speaking, a managed service provider (MSP) remotely monitors and administers hardware on a client's site on a subscription basis. Because not all hardware lends itself to this model, some MSPs provide on-site hardware for clients and build its cost into their fees. However, this arrangement puts financial strain on the MSP. The HaaS model, in which the vendor allows customers to license the hardware directly, was developed to alleviate that financial strain.
