CLOUD COMPUTING - Essay Example ). Moreover, cloud computing consists of applications that are represented as a service on the web and the provision of hardware / software services provided by companies operating data centers. Likewise, the services provided over the Internet are referred as (Software as a Service) ‘SaaS’. There are few sellers who use the term (Infrastructure as a service) ‘IaaS’ and (Platform as a service) ‘PaaS’ in order to demonstrate their products and services. However, these terms are avoided and not accepted globally, due to variation (ARMBRUST, FOX et al. 2010). The Commerce Department’s National Institute of Standards and Technology (NIST) have illustrated some helpful definitions that focus on three concepts (Ryan, Loeffler 2010): Cloud infrastructure as a service ‘IaaS’ consists of provisioning elementary computing resources. Cloud software as a service ‘SaaS’ access software application that operates on a cloud inf rastructure. Cloud platform as a service (PaaS) provides the accessibility to users for implementing and developing applications with programming language and tools supported by the providers. The core components of a cloud are consists of the data center hardware and software. When these resources are made available to the public, they are referred as public clouds and the service provided by the cloud is called as utility computing. Moreover, private clouds are only available to private organizations and are not accessible by public. Accordingly, cloud computing is the combination of ‘SaaS’ and utility computing (ARMBRUST, FOX et al. 2010). Current Trends Information Technology organization has already invested millions since the 1990’s, to contribute in reshaping cloud computing. For instance, a popular slogan from Sun that was â€Å"Network is a computer† was recognized in 1980’s. Furthermore, salesforce.com, a ‘SaaS’ enabled websit e is providing services since 1999.

Moreover, Yahoo has also announced recently that it will utilize ‘Apache Hadoop framework’ that will enable users to work on thousand of nodes and one million bytes of data. Accordingly, the contribution of cloud computing is covering every aspect of computation required for small, med ium and large businesses (Han 2010). Benefits Cloud computing provide many cost effective short term and long-term benefits. The organizations can avail services from multiple cloud-computing providers, to improve computerized business processes and high availability of services within the organization.
