We’ve been moving all of our infrastructure from the rock solid #Mesos (with Singularity) platform others and I built up over years, to #Kubernetes. It’s going well and all our stuff works.

But, you sort of forget all of the operational improvements and optimizations you have made until you move to a new platform.  Lots of little things to resolve, rough edges or bad ergonomics that we will need to address.  Shout out to HubSpot’s Singularity scheduler (RIP) on Mesos for being so great to operate.  Set a high bar.
