Cloud Computing: Analysis of Top 5 CSPs in SaaS, PaaS and IaaS Platforms

Abstract

The Cloud computing refers to manipulating, configuring and accessing the applications as utilities over the internet. It involves online data computation, storation, infrastructure and application, and hence it is highly essential to make a smart decision, when and how computing, storage and network resources be distributed and allocated to users to utilize, manage and consume them. In this paper first architecture of cloud computing, characteristics of service models and services provided by CSPs are discussed, than after analyzed growth rate and market share of top five CSPs in cloud service models, i.e Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS)
