In order to understand the concept and definition of Cloud Computing we need to focus on the three models described by The Commerce Department’s National Institute of Standards and Technology (NIST) (Bento & Aggarwal, 2013):
The ‘PaaS’ service of cloud computing allows the users to access the applications in order to deploy or develop any program or programming language. Moreover, the vendor also provides supporting tools for users.
The Cloud consists of basic elements related to the data center software and hardware. Utility computing refers to the services made available by the cloud. In addition, the cloud also provides services to the public as well. On the other hand, the remote services are only made available for the related business organizations only and are not reachable to the public. Therefore, cloud computing is considered as the amalgamation of the two i.e. utility computing and ‘SaaS’ (ARMBRUST et al., 2010).
Platform as a service: in the ‘PaaS’ is a cloud computing service concept there are three other elements that are present such as, platform, software, and infrastructure. software or any other application can only be accessed by the organizations if it is implemented via the vendor’s infrastructure or third party platform.
Infrastructure as a service: in the ‘IaaS’ the three elements are the same as present in the platform as a service. The services can only be given by the organization if the software is implemented by the cloud computing platform or another vendor.
Organizations should operate the services if they are provided by the sellers. These services must be provided in the form of applications and can be accessed via the Internet. In addition, the elements are subjected to the vendor’s property (Wilshusen 2011).  ...Download file to see next pages Read More

Different SPI Models of Cloud Computing

...Cloud Computing Service Models... Cloud Computing Service Models... is cloud computing? What defines it? Oftentimes, we have heard about cloud computing in schools, offices, workplaces, and even on television but do we have complete knowledge of what cloud computing really is? Perhaps, for somebody who is majoring or has majored computer-related courses in college, or for someone who works in an IT industry, cloud computing would not sound so trivial or intriguing at all but for the laymen, it may sound awkward – clouds and computer together? What relates them? First of all, cloud computing has nothing to do with clouds. Cloud computing is actually a colloquial expression that refers to an array of varying types of computing concepts that consist...

...Cloud Computing Service Models... Cloud Computing Service Models... Companies of large size have the financial as well as functional resources to own and operate their own data centers; however, smaller companies do not have the capabilities to do the same. This has given rise to a concept where companies make use of applications and data hosted on a hardware platform owned by another organization. This concept is referred to as cloud computing. In the simplest of terms, cloud computing can be described as providing hardware, systems, software, and applications as services over the internet (Gilam, 2010). The services are dynamically scalable. A cloud can either be public cloud (it is made available to public on a pay-as-you-use manner) or a...
