File systems are seemingly inescapable, if not just for "legacy" applications, perhaps just because they fit the requirements. The cloud-native world at first eschews "local storage," but the need to continue using that metaphor persists. Plus, in many existing, so called "legacy" systems, you have to work with both new types of storage and good, old fashioned filesystems, even NFS! In this episode, Coté talks with DellEMC's Julian Hjortshoj who works on Cloud Foundry Volume Services about his (and Paul Warren)'s talk at CF Summit on this topic. We first cover the basics of what's needed, how it works from the perspective of a user (i.e., an application developer) and how it's all handled behind the scenes, all the way back to the actual storage systems. If you're interested in that, be sure to come to the CF Summit, June 13-15, 2017. You can get 20% off registration with the code cfsv17cote. Full show-notes: http://pivotal.io/podcast
