MyBinder.org offers limited computational resources that don't require login. You can use Python, Jupyter, R, terminals, interactive dashboards in Voila or Shiny, shell-based resources and many other languages/abilities there. A substantial limitation, there to try and prevent abuse, is no outgoing FTP from the remote computers you session runs on in a container. Sessions on these remote machines are ephemeral though (another means to limit abuse), and so make sure you immediately download back to your local machine anything useful you generate beyond the included materials. I go in to general 'Getting Started' details here and describe the safety net only for Jupyter notebooks that is built in for when your session times out, here.
Samples of MyBinder use that I happen to have handy:
A snakemake tutorial that uses MyBinder.org to provide RStudio as the GUI, run by Titus Brown.
Example I made to illustrate some utility scripts for handling PDBePISA-based data is here. Go there and click
launch binder to get started. The idea is that everything is installed and then after working through the examples, users can adapt them right there to analyze the structures of their favorite protein or protein-nucleic acid structures.
Metagenome-Atlas Tutorial in Jupyter from Metagenome-Atlas Tutorial. After the session launches, click the 'Python' directory in the navgation panel on the left and then open and run the notebooks
Notebooks demonstrating how Clustergrammer2 can be used explore datasets in sessions served via MyBinder, go here and look for the '
launch' badges to get started.
Public offerings are going to vary by country and institution affiliations. I don't know about your country. In the United States, we have CyVerse for scientists that gives resources to scientists who register. You can share data and run a lot of tasks in what is essentially a managed version of Jetstream. I believe CyVerse has some international affiliations as well.
Commerical services are happy to sell you whatever resources you want to buy. A lot of them have free tiers or a trial time that allow you to run things. Some even offer educational grants of computer time to help people run training sessions. In fact, before MyBinder.org and CyVerse, this was how the training that got me started via what is now the 'Data Intensive Biology Summer Institute' was offered. And I have used that route over the years as sometimes you need more power, or flexibility, than MyBinder.org or CyVerse provide. Obviously arranging how to pay for these resources is the limitation. A lot of institutions now have affiliations with various providers. Often though it isn't easy if those connections don't already exist. In the United States, NIH has partnerships now with several of the big commercial cloud offerings, see here.
