Commodity computing is the use of standard, off-the-shelf hardware and software to build and operate computer systems. It involves using components that are widely available and inexpensive, rather than custom-built or proprietary solutions.
Commodity computing is often used in large-scale computing environments, such as data centers or cloud computing platforms, because it allows for economies of scale and cost savings. By using standard components that are readily available and easy to replace, companies can reduce the cost and complexity of building and maintaining their systems.
Commodity computing is also sometimes referred to as "commodity hardware," as it involves using standard, off-the-shelf hardware components, such as processors, memory, and storage devices, rather than custom-designed hardware.
