The business case for using grid computing involves all of the following except: speed of computation. cost savings. agility. increased computational power. centralized maintenance.

The solution to this question is given below in explanation section. The correct option is centralized maintenance.

Explanation:

Grid computing  is created to provide specific solution to problems that require to access large amount of data in business.

Grid computing occurs on a network of computing resources managed with advanced forms of middleware, which are called grid services. Grid services provide access control, access to data, security, including digital libraries , and access to large-scale interactive (e.g. server farms) and long-term (digital archives) storage facilities and deep web databases. Grid services are being replaced by open source web services, which perform the same tasks and have been developed over a longer period of time.

The business case for using grid computing involves speed of computation, agility, and increased computational power. However, in business case, grid computing does not involve centralized maintenance.
