We officially support two different SLAs:
-
"API-responsiveness": 99% of all API calls return in less than 1s
-
"Pod startup time: 99% of pods (with pre-pulled images) start within 5s
This should be valid on appropriate hardware up to a 1000 node cluster with 30 pods/node. We eventually want to expand that to 100 pods/node.
For more details how do we measure those, you can look at: http://blog.kubernetes.io/2015_09_01_archive.html
In the future we may want to add more SLAs (e.g. scheduler throughput), but we are not there yet.
