Two cloud-based systems that I use are Dropbox and iCloud. Dropbox is a file hosting service operated by the American company Dropbox that offers cloud storage, file synchronization, personal cloud, and client software. This can be used to share documents with other users or to save documents and other content without using up your own storage. iCloud is a cloud-storage and cloud-computing service from Apple Inc. This service is used to save personal information and to back-up information from Apple products such as iPhones, iPads, Mac computers, and can be accessed from Windows as well. All you need is an Apple ID, then you can enjoy the limited perks of iCloud web-only access without needing an Apple device. The cloud makes it possible to save and share large files and save a lot more data as there is essentially no limit. The advantages of a system on a distributed network are scalability, cost-effectiveness, and performance. When it comes to security and privacy concerns cloud storage is designed from the ground up for maximum data security. When you store data in the cloud, your files are encrypted and continuously monitored to protect against cybersecurity threats. Your data is also stored redundantly to ensure that a copy will survive any catastrophe.
