DEVOPS DAYS MTL 2018 - James Shubin
summary
A new config tool called MGMT actually exists: an MGMT engine in Go runs DAGs in parallel, watches resources and fixes changes in milliseconds, and forms a raft-based cluster for HA. A small functional reactive DSL describes time-varying values, historical indexes, and immutable variables so compiled code can’t crash. Live demos show a file recreated instantly, a distributed host key/value map syncing across nodes, and an autoscaler using 10s hysteresis to avoid flapping — all working on real machines.
