Istio Service Mesh & pragmatic microservices architecture

We have been celebrating 2018 as the Year of the Service Mesh, where an open source effort known as Istio has taken and changed how we design and release our applications. As we start to go toward cloud-native infrastructure and build our applications out of microservices, we must fully face the drawbacks and challenges to doing so. Some of these challenges include how to consistently monitor and collect statistics, tracing, and another telemetry, how to add resiliency in the face of unexpected failure, how to do powerful feature routing and much more. Istio and service mesh in general help developers solve this in a non-invasive way. In this session, we’ll show how you can take advantage of these capabilities in an incremental way. We expect most developers haven’t adequately solved for these issues, so we’ll take it to step by step and build up a strong understanding of Istio, how to get quick wins, and harness its power in your production services architecture.
