There are two primary reasons to use a cloud server. Service providers use a commercial cloud service, such as Amazon's AWS, because it lets them easily ramp up their resources when demand is higher and ramp down their costs when demand is lower. Cloud storage providers, such as Google Docs, allow users to access their data from any device and share data with others.
The OwnCloud package transforms your Linux server into a private cloud storage system. You can use an OwnCloud server as a private corporate file sharing system to share files with friends or as a remote backup for your phone or tablet.
The OwnCloud project forked in 2016. The NextCloud server and applications are expected to use the same protocol as that of OwnCloud and to be interchangeable.
