Explanation/Reference:
Using a grid computing architecture, organizations can quickly and easily create a large-scale computing infrastructure from inexpensive, off-the-shelf components (D). Other benefits of grid computing include
* Quick response to volatile business needs (B)
* Real-time responsiveness to dynamic workloads
* Predictable IT service levels
* Reduced costs as a result of improved efficiency and smarter capacity planning (A) Note: One way to think about grid computing is as the virtualization and pooling of IT resources- compute power, storage, network capacity, and so on-into a single set of shared services that can be provisioned or distributed, and then redistributed as needed.
As workloads fluctuate during the course of a month, week, or even through a single day, the grid computing infrastructure analyzes the demand for resources in real time and adjusts the supply accordingly.
Grid computing operates on three basic technology principles: Standardize hardware and software components to reduce incompatibility and simplify configuration and deployment; virtualize IT resources by pooling hardware and software into shared resources; and automate systems management, including resource provisioning and monitoring.
Grid computing operates on these technology principles:
* Standardization.
* Virtualization.
* Automation.
