Open Source at re:Invent 2018

AWS re:Invent 2018 header


re:Invent 2018 is coming soon, with so many open source-related sessions that we barely have room to mention them all here! Across almost every topic area, there are sessions about AWS open source projects and services, as well as builder sessions, chalk talks, and more on how to use a wide variety of open source tools in your AWS stack.

So as not to make this post too overwhelming, the descriptions below are heavily edited for brevity and to emphasize their open source aspects. Please click the session links to see full descriptions, speakers, and date/time/venue information.

IMPORTANT: This list may be expanded and updated before, during, and after re:Invent. Also check the re:Invent catalog for changes in date/time/venue, and newly-added sessions and repeat sessions.
