    The web of collaborations between individuals and group of researchers continuously grows thanks to online platforms, where people can share their codes, calculations, data and results. These virtual research platforms are innovative, mostly browser-based, community-oriented and flexible. They provide a secure working environment required by modern scientific approaches. There is a wide range of open source and commercial solutions in this field and each of them emphasizes the relevant aspects of such a platform differently.

    In this paper we present our open source and modular platform, [`KOOPLEX`]{}[^1], that combines such key concepts as dynamic collaboration, customizable research environment, data sharing, access to datahubs, reproducible research and reporting. It is easily deployable and scalable to serve more users or access large computational resources.

Summary
=======

[`KOOPLEX`]{} is a platform for easy access to datahubs, for collaborative work, for developing new workflows and for creating and publishing static or interactive reports. It is clear from the user feedback regarding the platform instances mentioned in **Section \[sec:kooplex-usecase\].** that the combination of such integrated services is attractive. Accessing the various modules in the same user space speeds up analysis, code development work and sharing, not having to move data and files around between disconnected components. The platform has been designed in a way that the integration of new tools taken up by the research community is straight forward. This feature helps to keep up with the ever evolving user requirements.
