What is the concept behind cloud computing?

Question

Many Blog posts say that 2015 is the year of cloud. In this scenario where you don't need to make large upfront investments in hardware and then spend so much of your time to managing that hardware. Isn't it cool!

Simply to explain the core concept. I will explain it using an analogy i.e. electricity services. Let us take a example you have a fan and when you want to switch it on you simply push the button and fan is on you don't have to think how electricity is being served to you how it is being generated and how wiring is done and many more. Now think is as you have a application (Web, Mobile etc) and if you want to deploy the same and you do it traditional way then you have to focus on various aspects i.e. storage, hosting solution, scalability, agility, resources, security etc. So, now cloud computing comes into picture it just gives you a platform as you want and make it inexpensive as you have to pay as you consume the services. All you have to do is simply get your application to cloud and rest of things is being taken care by the cloud service provider itself. Which gives you more time to focus on your business and application rather than infrastructure and other scenarios.
