A Networking Approach to Grid Computing by Daniel Minoli

By Daniel Minoli

Deriving the grid metaphor from the electrical community of cables and tool stations, grid computing is and extension of the concept that of "computer time sharing" during which the computing setting goals at allowing the choice, sharing, and aggregation of geographically allotted assets in keeping with a number of issues vital to optimizing computing assets. Aiming his quantity at company IT execs, Minoli (managing director, modern Networks integrated) synthesizes the kingdom of the sector, masking such themes as grid advantages; parts and architectures; criteria; deployment concerns and techniques; grid approach economics; and conversation platforms for neighborhood, nationwide, and international grids.

The Grid 2. Blueprint for a New Computing Infrastructure

The Grid is an rising infrastructure that might essentially switch the way in which we predict about-and use-computing. The observe Grid is utilized by analogy with the electrical strength grid, which supplies pervasive entry to electrical energy and has had a dramatic impression on human functions and society. Many think that through permitting all parts of our details know-how infrastructure-computational functions, databases, sensors, and people-to be shared flexibly as precise collaborative instruments the Grid can have an identical reworking impact, permitting new periods of functions to emerge.

CHAPTER 2 Grid Benefits and Status of Technology This chapter examines the potential business benefits for considering grid technology in a corporate environment, while at the same time looking at some of the challenges to be faced and addressed.

These costs have remained somewhat fixed over the years, as shown in [127]. A new opportunity now exists to address these cost components. Some of these savings can be achieved by replacing a technology with another. Other savings can be achieved by technology simplification (such as virtualization). We have already cited anecdotal information in Chapter 1 pointing to nontrivial potential savings with grid computing. One researcher stated that “Service providers that are not planning to invest in a portfolio of IT utility services will be under increasing pressure to show they can still provide flexible, cost-effective IT infrastructure services supporting everchanging business applications and processes” [34].

Although cluster management systems such as Platform’s Load Sharing Facility, Veridian’s Portable Batch System, or Sun’s Sun Grid Engine can deliver enhanced distributed computing services, they are not grids themselves; these cluster management systems have centralized control, complete knowledge of system state and user requests, and complete control over individual components (such features tend not to be characteristic of a grid proper) [103].
