### Scalability SLAs
|
|
|
|
We officially support two different SLAs:
|
|
|
|
1. "API-responsiveness":
|
|
99% of all API calls return in less than 1s
|
|
|
|
1. "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.
