Cluster schedulers promise us ease of deployment with ultimate scalability. We designed an ambitious challenge to test these promises: schedule one million containers. We call this the Million Container Challenge (C1M). HashiCorp prides itself on creating technically excellent software, and the C1M is a test to showcase this. We tested Nomad against the C1M to ensure that we meet the needs of our users at any scale. A cluster of five Nomad servers scheduled one million containers in less than five minutes, a rate of 3,750 containers per second.
