SESSION TITLE Reinventing DevOps Practices for Blockchain Applications SESSION THEME DevOps SESSION OVERVIEW With the arrival of distributed applications that run on Blockchain, it is essential to rethink some of the basic aspects of DevOps. Few things that we take for granted in DevOps area are either irrelevant, impossible or too costly for blockchain applications. This session aims to explore the changes that the blockchain apps bring to the DevOps arena, using a hands-on demo of a sample blockchain apps. SESSION AGENDA Introduction Blockchain - A layman's explanation How blockchain apps are different from traditional apps? Demo of Different tools Hands-on demo on "DevOps for Blockchain apps" (Continuous Integration, Continuous Delivery, Monitoring with focus on TDD, BDD, etc.) Summary Q & A SESSION TAKEAWAYS Understanding the unique features and differences in blockchain apps New practices for implementing DevOps in blockchain apps Inspiration to try out few things in this niche area DURATION 90 Mins
