Okay, jokes aside. The cloud is a generic term for remote computing. There are many types of clouds, clouds for personal storage (such as Box, Dropbox, Google Drive, Microsoft Onedrive, etc), clouds for development storage (expandable, and infinite. S3, Google Cloud, B2), clouds for computing (Azure, Amazon EC2, etc). Many types for many uses.
Why might the cloud be of interest to you? Well, a couple reasons.
What about cloud security? While companies will do their best to keep your data secure. It’s important to keep an eye on privacy policies, terms of service and the like. No online computer is immune to being hacked, no matter what measures are in front of it. If you want to protect sensitive data, encrypt it before uploading (this is what we do with our backup service) to the cloud or keep it off the cloud. Also check out this article on cloud security.
