Cloud computing is an internet based on-demand technology which offers computing resources to its end users and support various IT business processes. Computing resources are physical infrastructure as a service that includes compute, storage and network etc. It refers to manipulating, configuring and accessing the applications online. In cloud environment, users assume infinite resources are available and pay according to the resources that they use. With the enhancement of technology, cloud service providers increases rapidly and provide new features. But to choose right service provider is very difficult for a cloud customer according to their requirements. In this study, five cloud service providers are discussed i.e. Amazon web services, Google, Rackspace, Microsoft azure, DigitalOcean and provides comparison of these cloud service providers. The cloud service providers were compared on the basis of service availability, cost, pricing model, access interface, customer support, documentation, programming languages, data security, operating system, windows support, free trial, and regions. From the findings of the study concluded that digital ocean cloud offers best cost and Rackspace provides 100% service availability using CloudHarmony benchmark provider.
