The cloud by the name indicates something which is very huge and present over a large area. Going by the name, in a technical field, Cloud is something that is virtual and provides services to end-users in the form of storage, hosting of apps or virtualizing any physical space. Nowadays, Cloud computing is used by small as well as large organizations for data storage or providing customers with its advantages which are listed above.
Mainly, three types of Services come associated with Cloud which are: SaaS (Software as a Service) for allowing users to access other publically available clouds of large organizations for storing their data like Gmail, PaaS (Platform as a Service) for hosting of apps or software on Others public cloud ex: Google App Engine which hosts apps of users, IaaS (Infrastructure as a Service) for virtualizing any physical machine and availing it to customers to make them get feel of a real machine.
Cloud Storage means storage of data away from users’ local systems and across the span of dedicated servers which are meant for this. At its earliest, CompuServe in 1983 offered its customers 128k of disk space which could be used to store files. Whereas this field is under active development and will be because of potential threats including loss of data or information, data hacking or masquerading and other attacks, many organizations have come forward with their own solutions to Cloud Storage and Data Privacy which is strengthening and stabilizing its future.
In this article, we will present some of the selected contributions for this concern which are open source and successfully being accepted by huge masses and big organizations.

Syncany is one of the lightest and open-source cloud storage and file-sharing application. It is currently being actively developed by Philipp C. Heckel and as of today, is available as a command-line tool and GUI for all supported platforms.
One of the most important features about Syncany is that it is a tool and requires you to bring in your own storage, which can be FTP or SFTP storage, WebDAV or Samba Shares, Amazon S3 buckets, etc.
Other features which make it an awesome tool to have are: 128-bit AES+Twofish/GCM encryption for all the data leaving the local machine, file-sharing support with which you can share your files with your friends, offsite storage as chosen by user instead of provider-based storage, interval-based or on-demand backups, binary compatible file versioning, local deduplication of files. It can be more advantageous for companies who want to use their own storage space rather than trusting some providers provided storage.
Not just a file-sharing or synchronization tool or software, Cozy is bundled as a complete package of functions that can help you build your complete App Engine.
Like Syncany, Cozy provides flexibility to the user in terms of storage space. You can either use your own personal storage or trust the Cozy team’s servers. It relies on some open source software for its complete functioning which is: CouchDB for Database storage and Whoosh for indexing. It is available for all platforms including smartphones.
Main features which make it a must to have Cloud storage software are: ability to store all the Contacts, Files, Calendar, etc in the Cloud and sync them between laptop and smartphone, provides ability to use to create his own apps and share them with other users by just sharing Git URL of the repository, hosting static websites or HTML5 video game consoles.
GlusterFS is a network-attached file storage system. Initially, started by Gluster Inc., this project is now under Red Hat Inc. After their purchase of Gluster Inc in 2011. Red Hat integrated Gluster FS with their Red Hat Storage Server changing its name to Red Hat Gluster Storage.
It is available for platforms including Linux, OS X, NetBSD and OpenSolaris with some of its parts licensed under GPLv3 while others dual-licensed under GPLv2. It has been used as a foundation for academic research.
GlusterFS uses a client-server model with servers being deployed as storage bricks. A client can connect to a server with custom protocol over TCP/IP, Infiniband or SDP and store files to the GlusterFs server. Various functionalities being employed by it over the files are file-based mirroring and replication, file-based stripping, load balancing, scheduling and disk caching to name a few.
Another very useful feature of it is that it is flexible i.e. data here is stored on native file systems like xfs, ext4, etc.

Git-annex is another file synchronization service developed by Joey Hess, which also aims to solve file sharing and synchronization problems but independent of any commercial service or central server. It is written in Haskell and available for Linux, Android, OS X, and Windows.
Git-annex manages the git repository of the user without storing the session into git again. But instead, it stores only the linking to the file in the git repository and manages the files associated with the link at a separate place. It ensures the duplicate of a file that is needed in case the recovery of lost information is required.
Further, it ensures the availability of file data instantly as and when required which prevents files to present on each system. This reduces a lot of memory overhead. Notably, git-annex is available on various Linux distributions including Fedora, Ubuntu, Debian, etc.
Yandex.Disk is a cloud storage and synchronization service for all major platforms including Linux, Windows, OS X, Android, iOS and Windows Phone. It allows users to synchronize data between different devices and share them with others online.

16. Cloud Storage Server
Cloud Storage Server is an open-source, secure, extensible, self-hosted cloud storage API for building your own private cloud storage solution. It is a self-contained tool therefore you do not need to install a separate web server or enterprise database engine and is designed to be relatively easy to integrate into your environment.
The underlying server software implements a complete file system similar to Amazon Cloud Drive and other providers. It supports file-based cloud storage operations such as folder hierarchy management, file upload/download, copy, move, rename, trash and restore, delete and more. It also features per-user quota management, and per-user daily network transfer limits and so much more.
These are some known Open Source Cloud storage and synchronization software which have either gained a lot of popularity over the years or have just been able to enter and make their mark in this industry with a long way to go. You can share any software that you or your organization might be using and we will be listing that with this list.

Hello, Thank You for this article. Two major ones missing as cloud clients are Cryptomator(.org) and Duplicati(.com).
All these are great. However, they share one big problem. Your data is stored on somebody else’s server. As soon as you store your data on a third-party server, you give the server owner control over that data. You can be very easily blocked from accessing YOUR data. There is no Federal Deposit Insurance Corporation for when the server owner goes out of business.
Can Nextcloud be configured with multiple servers so that It can be created like Dropbox or Google drive?
Nextcloud is the best free on the market!
You didn’t mention the best one out there – NextCloud, is a fork of ownCloud with all features free that are paid in owncloud and developers are from owncloud.
Thanks for notifying, we will include NextCloud in the article..
Thanks for sharing this awesome blog post with us. I really loved the stuffed that you have shared with us. I picked some of the parts from this article to compile the newest blog post on Cloud migration benefits and is now published on Cloudways blog.
