Abstract: Since the inception of cloud computing, people are in a dilemma about its novelty, model, adoption challenges, cost etc. They have a wide range of opinion from merely business hype to revolutionary boon for ICT industries. Our objective through this paper is to present a less cloudy picture of cloud computing and answer some questions: "how this concept came into existence?", "how did it evolve from an earlier 'calculating machine' to 'present cloud'?", "how it is different from existing computing models?", "who would benefit from clouds?", "is it for all?", "the adoption challenges especially security" and "how much clouds have progressed in the last year in the business domain?". Our study reveals that clouds have made unprecedented growth in the last year. Its adoption rate, popularity, benefits and domain, have expanded sharply, while challenges and reluctance towards it have shown decline. Our idea is to present maximum information under one roof.

Keywords: cloud computing; cloud survey; cloud challenges; cloud status; cloud evolution; cloud analysis; business clouds.
