  1. Data science in the
 cloud using Python Graham Dumpleton @GrahamDumpleton

  2. Who am I? Author of mod_wsgi, the Apache module for

    hosting of Python web applications using the WSGI interface. Have a keen interest in Docker and Platform as a Service (PaaS) technologies. Currently a developer advocate for OpenShift at Red Hat.
  3. Topics for today • What is Jupyter & who is

    using it? • How to provide Jupyter notebooks to many users. • Deploying a single Jupyter notebook to OpenShift. • Deploying JupyterHub to OpenShift. • Deploying a data processing cluster using Dask.
  4. What is Jupyter? http://jupyter.org/

  5. Who is using Jupyter? Individuals Collaborators Teachers Data-driven organisations use

    Jupyter to analyse their data, share their insights, and create dynamic, reproducible data science.

  7. None
  8. https://jupyterhub.readthedocs.io/

  9. Running a single
 Jupyter notebook

  10. Running on your local system pip3 install jupyter jupyter notebook

  11. Local installation (Pros) • Save notebooks/data locally. • Python virtual

    environments. • Select Python version. • Select package versions.
  12. Local installation (Cons) • Operating system differences. • Python distribution

    differences. • Python version differences. • Package index differences. • PyPi (pip) vs Anaconda (conda) • Effort to setup and maintain.
  13. Running in a container docker run -it --rm -p 8888:8888

    \ jupyter/minimal-notebook https://github.com/jupyter/docker-stacks
  14. Container images (Pros) • Pre-created images. • Bundled operating system

    packages. • Known Python distribution/vendor. • Bundled Python packages. • Docker images are read only. • Run in an isolated environment. • Don’t need to maintain the image.
  15. Container images (Cons #1) • More effort to customise experience.

    • Build a custom Docker image to extend. • Install extra packages each time you run it. • Images can be very large. • Multiple Python versions. • Packages that you do not need.
  16. Container images (Cons #2) • Access to and saving your

    notebooks/data. • Need to mount persistent storage volumes. • Configure a contents manager for external storage. • Ensuring access is done securely.

  46. Jupyter on OpenShift • Provides simplified deployment using a template.

    • JupyterHub customisable through use of Source-to-Image. • Can pre-build images with notebooks and required Python packages. • Can attach storage to notebooks for persistence. • Integrate with KeyCloak for user authentication. • Connect to backend cluster for distributed data analytics.
  47. My other side projects • Using JupyterHub for teaching in

    university. • Using remote kernel gateway with Jupyter notebooks. • Working with Spark as backend data analytics cluster. • Utilising GPUs for high performance AI/ML tasks.
