§ First met May 2015 in Silicon Valley, ™
§ Since then realization of "microservice-
based” infrastructure, launching soon
§ Scaling for free (almost), service discovery
via DNS
§ Many useful features, e.g., healing, secrets,
config maps
§ Gaps:
§ Persistence layer: currently too afraid to
run our "normal" databases in cluster
§ Transforming configs from chef to
Kubernetes
§ Many plans for future extension (e.g. auto-
scaling)
