The benefits of cloud is storing data and accessing from any device, cloud is a computer network to store, access and share data online, however cloud still have physical servers, so is social media part of the cloud? If so how it can be helpful?
For that matter even your email account is part of the cloud. You can have a couple of email accounts and store your data forever. You can use it from anywhere and any computer of your choice without having a fear of losing it.
At the first instance when there is the thought of creating a cloud server, it deals without a computer in physical capacity, but that is not happening, cloud means yours data is somewhere, if you have emails then it is stored in that company's website, so the basic idea in which cloud computing starts does not satisfy these aspects as physical server can be out of order as some years back the Amazon cloud services, which is a paid one lost many files, so even in this modern times we should be keeping offline records apart from online cloud uploads.
