- Grid Computing
- Connects geographically remote computers into single network to create virtual super computer by combining the computational power of all computers on the grid.
- Most CPU is used on an average 25% of time leaving idle for rest of time.
- Grid computing is possible due to high speed internet connections (economic)
- Grid computing depends on software to divide and apportion pieces of a program among several computers, sometimes up to many thousands.
- Client sw communicates with server sw application.
- Server sw breaks data into chunks that are parcled out to grid machines.
Client machine can perform their tasks while running grid application in background.
Example:
Royal Dutch/Shell Group
1024 servers running Linux – largest linux supercomputer
Grid adjust to accommodate fluctuating data volumes that are typical in seasonal business
- ON DEMAND Computing
- Refers to firm’s offloading peak demand for computing power to remote, large scale data processing centers
- Firm can reduce investment in IT infrastructure
- “Utility Computing” - suggests that firms purchase computing power from central computing utilities and pay only for amount of computing power they use similar to electricity
- Annual traffic surge for certain firm on seasonal occasions
- Automatic Computing
- Industry wide effort to develop systems that can configure themselves, optimize and tune themselves, heal themselves when broken and protect themselves from outside intruders and self destruction.
- Edge Computing
- It is multitier, load-balancing scheme for web based applications in which significant part of website content, logic, and processing are performed by smaller, less expensive servers located nearby users.
- There are three tier in edge computing – local client, near by edge computing platform and enterprise computer located in firm’s data center
- Request from user client computer are initially processed by edge computer
Business benefit of edge computing:
1. technology cost are lowered – no need to purchase infrastructure at its own data center
2. service level are enhanced for users – less time
3. flexibility of firm is enhanced coz it can respond to business opportunities quickly
- Cloud Computing
Cloud computing is Internet ("cloud") based development and use of computer technology ("computing"). It is a style of computing in which typically real-time scalable resources are provided “as a service” over the Internet to users who need not have knowledge of, expertise in, or control over the technology infrastructure ("in the cloud") that supports them.
It is a general concept that incorporates software as a service (SaaS), Web 2.0 and other recent, well-known technology trends, in which the common theme is reliance on the Internet for satisfying the computing needs of the users. An often-quoted example is Google Apps, which provides common business applications online that are accessed from a web browser, while the software and data are stored on Google servers.
