i. Autonomic computing
The computer system have self-management capabilities.
An autonomic computing system must include the following features: monitoring, analysis, planning, implementation, and Knowledge Base, and several parts constitute a circulatory system. They need to constantly run and perfect. The goal of autonomic computing can automatically manage itself and maintain its reliability. It is able to work autonomously intelligent middleware.
Some of data no need to save it and that only need to be monitored it. Because the data gave the network a big load. So autonomic computing can be handle it. Growing the number of users and connected devices. Business need more equipment and maintenance personnel it. Autonomic computing system can help company solves problem. The responsiveness and flexibility of the system can handle the unpredictable things. It has self-management, self-healing and adaptive functionality, the company does not have to hire a lot of staff to monitor the system.
Virtualization is a subset of the process performance logical group, or computer resources. User can use a better way than the original configuration to access these processes. New virtual part of these resources is limited erected from existing resources. eg, geographical or physical configuration. Generally within the meaning of virtualized resources include computing power and data storage.
Server virtualization software technology refers to the use of the substance of the host hardware or operating system of the end-user hidden, and set one or more abstract hardware platform. The hardware platform is flexibility configuration for the operating system. Such like the face of a real hardware. As a result, a variety of different operating environments (eg, Windows, Linux, etc.) can operate simultaneously on the same physical host, but its independence as the operation of the general in a different physical host.
iii. Green computing
"Green computing" refers specifically to people's efforts to reduce the use of information technology hardware energy consumption. Many energy generation still relies on coal and oil, and process a large amount of carbon dioxide emissions to the atmosphere. this reducing energy consumption, also known to reduce carbon emissions.
From power management can save a lot of energy expenditure. The power management of energy-saving measures include computer shutdown when not shorten the computer into hibernation, turn off the screen saver, the machine is set to low-power sleep mode, and the total power off when work. (eg. E-mail can reduces paper-consuming.) Energy-saving mode of the computer in order to reduce the company's electricity costs.
Define an enterprise resources planning (ERP) system. How do ERP systems help businesses achieve operational excellence?
Applications of enterprise manufacturing, financial, marketing and other related functions to achieve a balance. Internally, it is the integration of the corporate body of diverse resources to achieve the effective application of organizational resources through optimal planning and allocation system. Externally, through the network and system can do the combination of main customers and partners to form a horizontal or vertical integration of the global competitiveness of the virtual enterprise entity.
ERP is major of contribution about strategic management for the enterprise. Today, only the information technology in the pursuit of flexible production, rapid assembly, rapid delivery and product life cycles continue to shorten trend. The combination of the information and corporate resources. Making the right decisions at the crucial moment, satisfied the customer needs or wants in a timely manner. It was able to grasp the market opportunities. ERP plus e-commerce applications and ERP combined with the concept of supply chain management. This extending...
