The next cloud is a fork from ownCloud and was created in 2016 by ownCloud founder Frank Karlitschek from the source code. Nextcloud differs from ownCloud in that it offers functions by default that are only included in the Enterprise version of ownCloud.
Nextcloud focuses on security, which should meet industry standards. Therefore, there is access control to files, protection against Brutforce attacks and encrypted storage and transfer of data.
Kerberos authentication and two-factor authentication are integrated for access. In addition, the login can be secured with a token and support for one-time passwords is available.
In addition to storing files, content can also be shared with other users, servers and Nextcloud instances as with ownCloud. The search takes into account the text in documents and an index is built based on the information from images and documents.
If you want, you can also use Nextcloud for video calls and edit documents with Collabora, which is based on LibreOffice. Accordingly, Nextcloud understands the Microsoft Office formats DOC, DOCX, PPT, PPTX and the Open Document Format (ODF).
Nextcloud itself is installed on a Linux server, with one Raspberry Pi 2 or 3 being sufficient for domestic use, depending on the purpose. Access is via browser from the desktop computer.
In addition, there are desktop clients for Windows, Mac OS X and Linux that take care of the synchronization of the data with the server. For the smartphone and tablet with Android as well as iPhone and iPad with iOS, the Nextcloud client apps are available in the app stores.
