Nextcloud and Collabora scale real-time collaboration to hundreds of millions of users

Integration build on mature Global Scale architecture benefits large customers and smaller federated installations

Nextcloud GmbH, supplier of the globally most deployed self-hosted content collaboration platform, and Collabora, the driving force behind LibreOffice in the cloud, announce the result of a collaborative effort to make Collabora Online available to customers with tens of millions of users through the innovative Nextcloud Global Scale architecture. The technological advancements also benefit distributed, federated private clouds, enabling cross-cloud collaboration between separate Nextcloud servers that have files shared between them. Global Scale has been in production since 2017 in a commercial setup for tens of millions of users across 4 continents. Several other customers have deployed or began experimenting with Global Scale in the last 2 years. Thanks to the new integration, Collabora Online installations at multi-million user scale are now set to roll out.

Our mission at RENATER is enabling seamless collaboration between over a thousand research and education institutions in France in order to protect the security and confidentiality of data. We study and experiment deeply Nextcloud Global Scale for its highly scalability capacities and its reliability that fit the needs of our project.
— Alexandre Salvat, Drive Project Manager – Pôle Projets Transverses et Innovation (P2TI) – RENATER

As a mature and real world tested solution, Nextcloud Global Scale offers Nextcloud customers a way out of traditional, costly scalability limitations like data center uplinks, load balancers and database, storage and cache. Global Scale enables virtually limitless scalability of Nextcloud deployments at high cost efficiency by transparently distributing users across multiple nodes. This takes away the need for a central database, storage and cache solution, enabling individual nodes to take advantage of inexpensive commodity hardware to save costs and increase flexibility Single production nodes have already shown the ability to scale to 250.000 users as part of a larger Global Scale setup. Even the limitations of a single data center in terms of capacity and up-link do not limit the size of a Global Scale deployment, as nodes can be in any location. This also allows installations to improve performance by moving data closer to the physical location of users or enforce strict data locality rules to comply with legal or security requirements.

“As the market demands every deeper integration of content collaboration technology, partnering with a leading document collaboration provider like Collabora Productivity is the best way to deliver our customers the solution they need”, notes Frank Karlitschek, CEO of Nextcloud GmbH.
“Globally active, demanding enterprises require excellent, real-world tested and truly scalable solutions only our partnership offers.”

Within a Global Scale architecture, enhancements to Collabora allow users from different nodes to transparently collaborate in a single document editing session. This means a combined Nextcloud Global Scale + Collabora instance can deliver real-time document editing at a truly global scale, with users collaborating across data centers, countries and continents.

“As Collabora proceeds to deliver its document editing solutions to exceedingly large enterprises, we are excited to collaborate with a proven scalability leader like Nextcloud. This is vital to meet the needs of big organizations” said Michael Meeks, General Manager at Collabora Productivity.
“Large scale deployments require reliable service combined with the excellent user experience our partnership provides.”

Private users and smaller installations also benefit from the improvements to Nextcloud Global Scale and Collabora Online, gaining the ability to collaborate on documents they have shared between their private clouds. This federation feature, invented by Nextcloud team members and standardized under the Open Cloud Mesh OCS standard, lets users share files between different servers as easy as sending an email.
Several customers are expected to roll out Collabora Online in a Global Scale context, supported by Nextcloud and Collabora. For more information about a Global Scale deployment, contact Nextcloud GmbH.

Automatic Redaction – now more efficient redaction in Collabora Office


The new Automatic Redaction makes redacting even more efficient

The Redaction tool has been extended, for fast and automatic marking of text. This tool is designed you to hide words and other portions of a document that are sensitive, classified or private, so that you can safely share an image-pdf of the file with others. Its details are explained in a previous article.

And now, the new feature Automatic Redaction allows you to add words and patterns that then are found in the document and marked for redaction. It extends on features such as cooperating, preview, choice in style of hiding information. This makes redacting documents in Collabora Office really efficient. It works faster and helps considerably doing the job correct. Here is how it works.

How to use the Automatic Redaction?

  • The next image from Writer shows how to start from Tools > Auto-Redact.

  • The dialog has a list for redaction targets. It is simple to add items.

  • The selection list Type also allows to use regular expressions or choose from pre-defined types.

  • Also interesting is the possibility to save the list of targets to a json-file, and load them likewise.

  • Then with OK the file is converted to image with marked areas, and opened in Draw for further redaction, reviewing and final export as PDF.

As said, a previous article explains all basic features.

Want to start using the Redaction tool?

You can get a snapshot / demo of Collabora Office and try it out yourself right now!

ownCloud and Collabora Enable Setting up Virtual Data Rooms with New “Secure View” Feature

With “Secure View”, ownCloud and Collabora Online present a first of its kind, entirely new way of individually restricting data and information exchange. The fully controllable restrictions range from simple download deactivation to a highly-protected read-only option. Enterprise users thus can entirely control and meet the highest security and compliance standards when working together on digital documents. Thanks to Secure View, “virtual data rooms” can now be set up without expensive additional software.

Using Secure View, documents of all common Office formats (.docx/.xlsx/.pptx/.pdf) can be provided with comprehensive restrictions. These restrictions prevent the recipient of a file from editing or downloading it, copying/inserting content and from printing the document. An important part of sharing and collaborating in Secure View is that the text displayed on the computer is composed of images. The protected document itself never leaves the server. To add to these permissions, exporting or printing documents can either be entirely prohibited or can be restricted by generating a watermark. A watermark of this type displays individual user information. This ensures that it is always possible to draw conclusions about the person who passed on the document (without permission) – even when taking a screenshot or photo.

Maximum Security When Working Together on Documents

“With the development of Secure View, we can now offer our Collabora Online users even more ways to collaborate and work with documents that require a particular level of security,” Michael Meeks, General Manager at Collabora, points out. “Collabora Online and ownCloud complement each other perfectly by combining convenience and flexibility, when editing and viewing documents, with maximum data exchange security.”

Secure View is the basis for mode-based document sharing, whereby individual permission settings determine what the recipient of a file can do with it. In addition to individual access restrictions for specific documents, policies such as “view-only”, “comments-only” or “enforce change tracking” can also be automatically applied as soon as certain prerequisites are met. This way, “virtual data rooms” can now be established using Secure View. In these restricted areas within an ownCloud, sensitive documents are protected from unauthorized redistribution without impairing read access for authorized persons from anywhere. The only prerequisites are Internet access and a web browser.

All Data Remains on the Server

Typical use cases for Secure View are review processes of confidential documents or the controlled provision of sensitive information for a selected group of people. Since ownCloud is an on-premises private cloud solution, access to such secure data rooms can also be granted to external authorized readers without the original confidential data leaving the company’s servers – because the text displayed on readers’ computers is composed of images. This enables convenient collaboration, for example with consulting lawyers or R&D partners, while ensuring that security and compliance rules are met.

Secure View is the first feature which has been developed on the basis of “Advanced Sharing Permissions”, introduced in ownCloud 10.2. This technical foundation provides extension developers with the means to implement advanced individual permission settings at user and group level, thus maximizing security and control.

Document Protection Without Vendor Lock-in

While there are other software solutions for virtual data rooms available on the market, none of them offers a comparable level of security and control at the same time. One of these software solutions is Microsoft’s “Azure Rights Management”, to name just one example. It encrypts all documents and stores the decryption key in Microsoft’s Azure Cloud. To make this solution work, it is necessary to use Microsoft products across a large part of the corporate infrastructure in order to guarantee full protection and accessibility of the sensitive documents.The result is an architecture that is unnecessarily complex and highly dependent on a single vendor.

With the solution from ownCloud and Collabora, these two obstacles are eliminated. This way organizations stay in full control of where their sensitive data is stored and which software they can choose for editing and viewing documents. “Securely viewing” these documents only requires a web browser. So there is no vendor lock-in at any point of this process.

“The joint development of Secure View, an unprecedented feature, is a great example of what can be achieved with flexible integration solutions,” Tobias Gerlinger, CEO of ownCloud, comments on the cooperation. “In this way, we can offer our users enterprise-relevant new features without getting bogged down with too many different development ventures – as is the case with some competing products. For ownCloud, stability, security and performance of the core product are the top priorities.”
