Before the cloud computing era, the companies used to spend a lot of money on services like storage, computing, servers, etc. But now the internet is getting better and you are able to access your data and servers from anywhere through it. All the requirements to run your business including software and hardware are stored on cloud. Small and big companies have started using cloud to take the best out of it.
Amazon is a company that provides these cloud based services.
Hope this helps!
