How can you maximize release velocity for your cloud applications, while protecting end-user experience at all times? Service level objectives (SLOs), and safe, progressively rollout of new versions of your applications are two of the best-practices that address this problem. In this talk, we presented two demos using Iter8, the release engineering platform for Kubernetes) that shows delightfully simple ways to automate SLO validation and progressive rollouts for Knative applications.
