A Practical Guide to Continuous Delivery (Container Days 2017)

Abstract:

In this talk Ilya will outline what are the 3 pillars of CD – release management, validation and monitoring. After a short introduction to key concepts, Ilya will cover what Weave team has implemented in production for running Weave Cloud service (which, in turns, offers most of the same features used internally to its users). In the main section Ilya will turn the spotlight on the topic of monitoring and demonstrate the simplicity of cloud-native tools featuring a step-by-step demo of Kubernetes & Prometheus with a Node.js app.
