The ownCloud server stores user files in standard file system formats, and can use most file systems. With ownCloud, if you can mount storage on your server, ownCloud can use it. Practically, this means just about any standard file system and storage device combination can be used – ownCloud is file system and storage agnostic. The storage can be physically located in your data center (or be “mounted” to third-party storage), enabling you to protect your files as you would any other element of your infrastructure, from standard backups and intrusion detection, to log managers and Data Loss Prevention (DLP) solutions.
It is simple to Integrate ownCloud with existing IT infrastructure through the use of plug-in applications. These plug-ins can be enabled through the server control panel, provide functionality such as Active Directory (AD) and Lightweight Directory Access Protocol (LDAP) integration for user account provisioning and authentication. If an integration is not included out of the box, it is simple to extend ownCloud through open APIs and plug-in applications. Features such as the online text editor, virus scanner, and file versioning are included in ownCloud and other applications, such as the enhanced logging and audit plug-ins, are available to our customers. ownCloud customers have integrated a wide variety of new functionality into ownCloud, from training video streaming to contact and calendar syncing, custom authentication mechanisms, automated Optical Character Recognition back ends, and API-based storage. In short, unlike our competitors, ownCloud can be easily extended to do far more than basic file sync and share.

While ownCloud provides the ability to manage and protect, integrate and extend file sync and share in the enterprise, ownCloud still provides the core file sync and share functionality that users demand. Simple, web-based access through a standard browser to access, share, rollback and manage files is critical to satisfy users and remain in control of sensitive data. ownCloud also offers access to browse, download, edit, and upload files while on a mobile device or tablet, and the desktop client, which automatically syncs the latest files with the server. ownCloud also provides the ability for standard WebDAV clients to access ownCloud files, enabling users to continue to use standards-based productivity tools to access their files in addition to the standard ownCloud access tools.
Server Architecture Overview
============================
At its core, ownCloud is a web application, written in PHP, running on top of a webserver such as IIS, if on Windows or Apache, if on Linux. This PHP application manages every other aspect of ownCloud, from user management to plug-ins, file sharing and storage. Attached to the PHP-application is a database, where ownCloud stores users, user-shared file details, plug-in application states, and the ownCloud file cache to accelerate access to files. As ownCloud accesses the database through an abstraction layer, support is provided for Oracle, MySQL, MS-SQL Server, Postgres and SQLite. Complete webserver logging is provided via the webserver logs, and user and system logs are provided in a separate ownCloud log, or can be configured to a syslog log file.
To make it possible to access and use many different types of storage, ownCloud has a built-in storage abstraction layer. As a result, ownCloud can leverage just about any storage protocol that can be mounted on your ownCloud server – from CIFS, NFS and GFS2, to cluster file systems like Gluster. Other optional storage can also be mounted on the system using an optional external file system application, enabling admins and users to mount FTPs, WebDAV, CIFS and even external cloud storage services S3, Swift, Google Drive and Dropbox if desired. Individual users can also be configured to have dynamically allocated storage locations, depending on their user directory entries – enabling data segregation and basic multi-tenancy.
