Cloud computing is no longer a new term for people who are in the world of IT. Simply put, cloud computing is when you use the internet for storing and accessing data. Across all industries, cloud computing has become an integral part of businesses. Apart from reducing costs, it improves efficiency, allowing businesses for any number of services or products. With cloud computing, you don’t need to store the data on the hard disk of your personal computer. Instead, your data is stored within the cloud and you can access it from a remote server, whenever you wish to do so. With the advent of cloud computing, AWS has established itself as a top contender in the market.

According to Gartner, by 2020 a corporate “No-Cloud” policy will be as rare as a “no-internet” policy today. Another report by Forbes says that the global spending on public cloud services will grow at a 19.4% CAGR (Compound Annual Growth Rate) from around $70 billion in 2015 to $141 Billion in 2019.

AWS has been ruling over the cloud market in the past few years. These amazing figures show you how cloud services are being used worldwide, eventually depicting how rewarding a career in a cloud platform can be.
