RosettaHUB aims at establishing a global open data science and open education meta cloud centered on usability, reproducibility, auditability, and shareability. It enables a wide range of social interactions and real-time collaborations.
RosettaHUB leverages public and private clouds and makes them easy to use for everyone. RosettaHUB’s federation platform allows any higher education institution or research laboratory to create a virtual organization within the hub. The institution’s members (researchers, educators, students) receive automatically active AWS accounts which are consolidated under one paying account, supervised in terms of budget and cloud resources usage, protected with safeguarding microservices and monitored/managed centrally by the institution’s administrator. The cloud resources are generally paid for using the coupons provided by Amazon as part of the AWS Educate program. The Organization members’ active AWS accounts are put under the control of a collaboration portal which simplifies dramatically everything related to the interaction with AWS and its collaborative use by communities of researchers, educators and students. The portal allows similar capabilities for Google Compute Engine, Azure, OpenStack-based and OpenNebula-based clouds.
RosettaHUB leverages Docker and allows users to work with containers seamlessly. Those containers are portable. When coupled with RosettaHUB’s open APIs, they break the silos between clouds and avoid vendor lock-in. Simple web interfaces allow users to create those containers, connect them to data storages, snapshot them, share snapshots with collaborators and migrate them from one cloud to another. The RosettaHUB perspectives make it possible to use the containers to serve securely noVNC, RStudio, Jupyter and to enable those tools for real-time collaboration. Zeppelin, Spark-notebook and Shiny Apps are also supported. The RosettaHUB real-time collaborative containerized workbench is a universal IDE for data scientists. It makes it possible to interact in a stateful manner with hybrid kernels gluing together in a single process R, Python, Scala, SQL clients, Java, Matlab, Mathematica, etc. and allowing those different environments to share their workspace and their variables in memory. The RosettaHUB kernels and objects model break the silos between data science environments and make it possible to use them simultaneously in a very effective and flexible manner. A simplified reactive programming framework makes it possible to create reactive data science microservices and interactive web applications based on multi-language macros and visual widgets. A scientific web based spreadsheet makes it possible to interact with R/Python/Scala capabilities from within cells which includes variables import/export and variables mirroring to cells as well as the automatic mapping of any function in those environments to formulas invokable in cells. Spreadsheet cells can also contain code and code execution results making it become a flexible multi-language notebook. Ubiquitous docker containers coupled with the RosettaHUB workbench checkpointing capability and the logging to embedded databases of all the interactions the users have with their environments make everything created within RosettaHUB reproducible and auditable.
The RosettaHUB’s APIs (700+ functions) cover the full spectrum of programmatic interaction between users and clouds, containers and R/Python/Scala kernels. Clients for the APIs are available as an R package, a Pyhton module, a Java library, an Excel add-in and a Word Add-in. Based on those APIs, RosettaHUB provides a CloudFormation- like service which makes it easy to create and manage as templates, collections of related Cloud resources, container images, R/Python/Scala scripts, macros and visual widgets alongside with optional cloud credentials. Those templates are cloud agnostic and they make it possible for anyone to easily create and distribute complex data science applications and services. The user with whom the template is shared can with one-click trigger the reconstruction and wiring on the fly of all the artifacts and dependencies. The RosettaHUB templates constitute a powerful sharing

mechanism for RosettaHUB’s e-Science and e-learning environments snapshots as well as for Jupyter/Zeppelin notebooks, shiny Apps, etc. RosettaHUB’s marketplace transform those templates into products that can be shared or sold.
The presentation will be an overview of RosettaHUB and will discuss the results of the RosettaHUB/AWS Educate initiative which involved 30 higher education institutions and research labs counting over 3000 researchers, educators, and students.
