Making the move to microservices, containers and orchestration? In this webinar we’ll show how to deploy and configure pods to ensure high availability and how pods connect to let the outside world reach your app. In this webinar you'll learn: * Kubernetes core concepts * Masters, nodes and how to register nodes to clusters. * What to monitor and visualize, and using what tools.

● Heapster
● Prometheus
● Sysdig

12. Visualizing data with Grafana

13. Alert mechanisms &
proactive actions
13
● K8s native alert mechanisms
■ Autoscaling app
● Infrastructure scaling with Mist.io and
Cloudify
■ Scale cluster up and down based
on resource usage
■ ties to cost reduction; better
utilization and reduced costs
