In this article I would like to introduce you to the most important features and benefits of Collabora Online, explain the possibilities of using it to meet data protection requirements together with Nextcloud or ownCloud, and show you how easy is to integrate and operate Collabora Online with Univention Corporate Server (UCS). You will also learn that Collabora Online in UCS offers a pre-built environment, pre-configured packages and a friendly UX that makes the integration process extremely easy and straightforward by including Nextcloud or ownCloud appliances preconfigured as data storage. At the end, you will get a short overview about the main differences between our two versions: Collabora Online Development Editon (CODE) and the supported Collabora Online, both available in the Univention App Center.

What is Collabora Online? – your own private office suite

Collabora Online is an open source software component based on LibreOffice that can be easily integrated into any web application, and which enables viewing and collaborative editing of Office documents in dozens of file formats.

Collabora Online includes support for text documents, spreadsheets and charts as well as presentations. It provides an easy-to-deploy office suite that runs directly in any modern browser, on all your devices.

Stay in control over your data – on-premise, on your own terms and easy-to-deploy

Being able to easily deploy Collabora Online on Univention Corporate Server on-premise makes it easy to protect all of your data and documents. In addition you can keep the processing and communication on your own hardware and (virtual) network. This keeps all of your data inside the right jurisdiction and control and makes GDPR compliance very easy. In contrast, even when a public clouds locates data in a given jurisdiction, people from outside can access the same hardware and potentially access your data. On-premise Collabora Online can protect you from this – making it ideal for certain industries, such as Pharmaceutical, Medical, Health, Education or Finance and Banking, Insurance, Legal and/or Military – as well as privacy conscious home users.

Enterprises can get access to our huge depth of experience, combined with long term support, security maintenance and ease of deployment features, while home users can enjoy and try out the very latest technology.

The key is powerful document interoperability

Collabora Online gives all users access to the leading non-Microsoft implementation of an Office suite, with the ability to provide high fidelity import, rendering, editing and export of the vast majority of extant office documents formats.

While our native document model is inspired by the Open Document Format (ODF), Collabora Online, can import and export Microsoft DOCX, DOC, RTF, XLSX, XLS, PPTX, PPT and their macro containing variants such as DOCM or XLSM.

In addition Collabora Online has support for viewing many other file formats such as PDF, Visio, Publisher, Keynote, Numbers and Pages as well as many other more obscure formats. And of course, Collabora Online has a responsive mode, allowing collaborative editing and a touch UI for any kind of mobile devices with a browser, such as iOS (iPad or iPhone) and Android.

Collabora Online in Nextcloud and ownCloud makes collaboration easy and efficient

Collabora Online provides rich document editing but it is necessary to marry this with data storage and authentication. Thankfully both Nextcloud and ownCloud share our vision of secure,- on-premise data management – and provide rich underlying storage and authentication infrastructure for our product.

With Collabora Online for Nextcloud and ownCloud you will get the security you need. You are in full control of sensitive corporate data and you can deploy multiple instances wherever you like, to suit taste, collaborators, and security.

Once you have completed a simple graphical setup with a web-based administration interface, you can use the online office and cloud file sharing solution directly.

Collabora Online in UCS offers a pre-built environment, pre-configured packages and a friendly UX that makes the integration process extremely easy and straightforward.

In the appliance, Nextcloud or ownCloud are already preconfigured as data storage for Collabora Online. This way you save the additional effort of installing and configuring a data storage plugin.

    You say ” it has a limitation of 10 documents and 20 users.” I believe this was for a release made about 3 years ago, I don’t think it is true now, can it be corrected? Or is it still true?
