Utility computing - Introduction

Utility computing is referred to be known as a facilityprovided by such providers to variety of users on theredemand and also charge them in return of using thisservice on the basis of using in short specific usage. Aswell as it also provides infrastructure to the users orcustomers. Utility computing is a model of providingfacilities on demand of customers as other demands arefulfilled of grid computing etc. The utility model providesthe benefit of using the tools maximum on demand aswell as better usage of resources and to minimize thecosts. The word utility is an analogy for the customers touse and pay for the quantity of usage. Like electricity ischarged on the extent we use rather than paying full partas school fees or college to join class or not but have to

pay but the utility computing provides this facility of pay per use. The term utility computing is taking place insociety in different dimensions also like enterprise computing, website access, file sharing, different applications,used by the consumers in markets. Some other version of utility computing is taken from the enterprise known asa shared pool utility model which centralizes its computing resources to serve a larger number of users withoutunnecessary redundancy.

Utility computing provides the ability to all companies to access computing services, business processes, andapplications from a utility-like service over a network. This influences in term of being saving their money viausing the capability on just pay per use. This means all companies can save their money via this utility.To buy hardware is the alternative that can face the peak loads and how to solve such problems. Utilitycomputing can be considered as the tool for gradually advancement from application service providers. The mosthighlighting technology for utility computing is web computing and the networking of connected storage andCPUs from multiple systems into a managed system. but it is the computing system that is flexible in itsenvironment.Utility computing worthy ideaUtility computing is the way which handles computing resources such as storage of data, computation andservices that is familiar to a systematically public utility. Natural gas, water, electricity or telephone network issome of its examples. This way has the benefit of a low or initial cost to acquire computer resources. And thecomputational resources are necessarily rented turning that has been a need to purchase products in past.Hardware, software and network bandwidth are among of them into service. The re packaging of computingservices works in a way that it became the foundation of ‘on demand’ computing service. Cloud computing andsoftware (as a service) works that further reproduces the idea of computing, application and network as aservice. Utility computing can keep stable with grid computing as it has the capability of a very large

computation. Importance of utility computing:The utility computing sometime demands a kind of cloud strategy because it highlights the model, which can beknown as business model that also provides the computing services. The customer receives computing resourcesin utility computing resources that resources provide service like hardware, or software. It is like you would dofor your electric service at home. It is defined in the term of ‘pay by the drink’ which is an analogy from ‘the bigswitch’ by Nicholas Carr

Features of Utility ComputingThe major advantage and benefit that can be getting from utility computing is better economics. Corporate datacenters are better used in a way that with the resources, often idle 85 percent of the time. The main cause behindthis is the large number of buying the hardware that is more than average need of that hardware which causesthe problem to handle the expected future burdens. So the utility computing plays its best by allowing thecompanies to only pay for the computing resources they need.
