Cloud computing is Internet-based computing‚ whereby shared resources‚ software and information are provided to computers and other devices on-demand‚ like a public utility. It is a paradigm shift following the shift from mainframe to client-server that preceded it in the early ’80s. Details are abstracted from the users who no longer have need of‚ expertise in‚ or control over the technology infrastructure "in the cloud" that supports them.[1] Cloud computing describes a new supplement‚ consumption

Type of Cloud Computing Cloud Computing can be divided by two main criteria. The first criterion is service models‚ and another criterion is deployment models. Service Models For service model criterion‚ cloud computing can be divided into three types which are software as a service (SaaS)‚ platform as a service (PaaS) and infrastructure as a service (IaaS) Software as a Service (SaaS) The first service model‚ software as a service‚ likes an online application.

These days "cloud computing" is the buzzword used to describe the direction in which information network infrastructure seems to be leaning towards. The authors reasoned that cloud computing sprouted from grid computing‚ distributed computing‚ and parallel computing‚ which resonated with the works of Foster‚ Zhao‚ Raicu‚ & Lu‚ 2008 [1]. And like many‚ they found it a challenge to provide an encompassing definition for cloud computing. Foster et al. defined cloud computing as‚ “A large-scale distributed

Distributed System: Distributed computing is a field of computer science that studies distributed systems. A distributed system consists of multiple computers that communicate through a computer network. The computers interact with each other in order to achieve a common goal. A computer program that runs in a distributed system is called a distributed program‚ and distributed programming is the process of writing such programs. Distributed computing also refers to the use of distributed systems to solve
