What is a commodity server?
In the context of IT, a commodity server is an easily available, universal, standardized and highly compatible piece of hardware on which various types of software programs can be installed. It is simply a computer system that has server-side programs installed on it that can perform related tasks. The hardware used in such servers is readily available and can easily be replaced.
Commodity servers, as the name suggests, are servers that are not built for a specific purpose. These are general systems that have been converted for use in low-level networks. They usually take the form of a group of servers that perform certain server-based tasks together. The hardware is usually easily replaceable and inexpensive. The advantages of using commodity servers are that they are not tied to specific brands and vendors, are easy to maintain and readily available compatible components. They are ideal for storing and retrieving data from large databases where the server does not perform highly technical tasks.
