A cloud is a blend of hardware, storage, networks, interfaces and services that aid in delivering computing as a service. A cloud consists of three users:end-user, cloud service provider and business management user.
The basic four characteristics of cloud computing are:
a) Scalability and elasticity – Increase or decrease services on demand
b) Self-service provisioning – Help yourself in major problematic scenarios without waiting for the response of your provider
c) Pay-per-usage billing model – Pay for what you use
d) Standardized interfaces – Interfaces applicable to all major models
