OwnCloud – a Private Cloud

Many organizations nowadays are using cloud to synchronize files present in many locations over the Internet. Cloud vendors are providing completely different software for this purpose. However, it's crucial to keep up the protection of those files within the cloud that is often a serious concern to the business enterprises. Moreover, the matter lies in using the proprietary code wherever it finds terribly overpriced to share the files often on routine work schedule.

To overcome these problems, an open-source software ownCloud is developed that offers file synchronizing and file sharing options firmly. It offers the users to access files quickly through the WebDAV. It can be used to view and access the user details, set the date and time, bookmarks across all the cloud user systems. The server software is downloaded and put in within the UNIX system server and solely smallest efforts are needed while not the necessity for special permissions. It is extendible employing a plain however authoritative API for plugins and alternative software applications. On the other end, the clients shall be either desktop/ mobile for data synchronize. Desktop clients support Windows 7, 8.x, 10 versions, UNIX system distributions and raincoat OS X versions, while Apple AppStore, Android, Google Play and BlackBerry systems are mobile purchasers.

OwnCloud has the subsequent options that makes it to be wide used as private cloud:

1. Access share and synchronize user data. Files, image galleries, calendars, contacts, etc. are accessed, hold on and synchronized on a server preferred by cloud users. Keep data is accessed and shared either public or private with other users from the user’s desktop systems, mobile devices or an online browser. The files with recent versions are obtained anytime with the desktop systems, mobile app, or Internet client.
2. Versioning. An important feature that ought to be enabled in any application for retrieving the recent files, ownCloud habitually saves the recent files of the cloud users in several versions. The choice relating to what extent data is saved shall be done by configuration. To revert the changes, one's file shall be moved to the sooner version.
3. Encryption. As ownCloud is private and used solely among the organization, securing the files is critical that is achieved by encrypting them. File Firewall provides restricted access to its cloud users and administrators to follow the access rules related to its server. The determination of file access is set by the granularity of rules.
4. Drag and drop transfer. With this feature, a user need not want to install the complete ownCloud client and he may simply go online to the net browser directly. Then he may drag the files from desktop systems and drop them into the preferred target folder into the net browser where the ownCloud client resides.
5. ODF Files Viewer. Using this characteristic, anyone may view the open document formats and shall click on any ODF formatted document for reading it from the net browser while not downloading.
6. Migration, backup and logging. Many occurrences of ownCloud installed with main and backup support may merely move ownCloud user accounts among ownCloud occurrences and shall comprise a backup set when required. ownCloud may also be used to write in system log files additionally to the present ownCloud log file that helps to keep track of the changes and access.
7. Tasks, calendars and application store. With the Tasks features enabled within the application, one may straightforwardly synchronize one’s to-do lists with the ownCloud occurrence. One can share necessary calendar and necessary events by enabling the Calendar feature. Any ownCloud users shall open the Calendar and by choosing the share option shall prefer the users or their teams for whom it ought to be shared. Enabling a new application in settings, one can add existing applications to ownCloud, which can be download-ed automatically in the ownCloud instance.
8. File notifications and galleries. The File Notification feature once given can build the files and its corresponding documents like movies, video clips, and others to be shared quickly and simply. One will specify the ownCloud picture directories in order to possess control, additionally sort order, share galleries with any email address by selecting, and control whether others can share those photos with anyone else.

Performance Measure of OwnCloud

It is needed to measure the performance of ownCloud that shall be considered as a very important issue for enhancing the speed of cloud operations. As several database applications reside on ownCloud, the scalability of huge clustered servers that are running parallel with central database storage is crucial. This happens because of the database queries that are raised often and is tough to scale them. The execution time of a large set of Lines of Code (LoC) is that the major thought for measure the performance of the sort of cloud that's employed in any enterprise. It's noted that the search with the large users’ files can take longer to complete the method instead it might never finish throughout the launching of such files within the CPU of the ownCloud server.

Conclusion
