• Bloomberg's powerfulseal is a really nice interactive or automated k8s chaos monkey, which lets you do sensible wargaming
• Bitnami released the new kube sandbox which spins up a single node "production"-like cluster vs minikube
• Buoyant released Conduit a more "kube-native" and simpler service mesh than istio. Worth investigating!
• Linuxkit has kubernetes os images. Here is an indepth article about it.
• Fluentbit is a much lighter weight version of fluend written in C originally for resource constrained systems.
• kata containers are VMs with the speed of Containers
• Having a subscription to Grafana Labs entitles us to Grafana Cloud Enterprise, their onprem
