Definition - What does Commodity Hardware mean?
Commodity hardware is a term for affordable devices that are generally compatible with other such devices. In a process called commodity computing or commodity cluster computing, these devices are often networked to provide more processing power when those who own them cannot afford to purchase more elaborate supercomputers, or want to maximize savings in IT design.
Techopedia explains Commodity Hardware
Another example of commodity hardware is a strategy for some businesses that involves using simpler server hardware, such as a collection of x86 servers to run simple or scaled-down database environments instead of upgrading to more expensive server equipment. This is another good demonstration of the philosophy behind commodity hardware setups, which is that less expensive and simpler equipment can be networked to provide more capability for business computing. Companies that embrace a commodity computing model are often able to save many thousands of dollars in IT procurement plans.
