Python on Cloud Foundry
Ian Huston discusses Python's integration with Cloud Foundry, an open-source cloud platform that simplifies app deployment and scaling. He highlights the benefits for data scientists, including easy setup of web applications and the ability to connect to various data services. The presentation also covers the use of buildpacks for Python applications and the introduction of Docker support for enhanced customization.
