## Scalability/performance SLIs and SLOs
|
||||
# Details about SIG-Scalability sub-projects
|
||||
|
||||
## Kubernetes scalability definition
|
||||
|
||||
Defining what does it mean that "Kubernetes scales".
|
||||
This includes defining (or approving) individual performance and scalability
|
||||
related SLIs/SLOs, ensuring they are all oriented on user experience and
|
||||
consistent with each other.
|
||||
|
||||
Measuring and publishing limits within which Kubernetes is supposed to scale
|
||||
as defined above and providing recommendations about setting clusters in
|
||||
scalable and performant ways.
|
||||
|
||||
* [Kubernetes Scalability SLIs/SLOs](./slos/slos.md).
|
||||
|
||||
## Kubernetes scalability governance
|
||||
|
||||
Establishing and documenting best practises on how do design and implement
|
||||
Kubernetes features in scalable and performance way.
|
||||
Educating contributors and ensuring best practises are widely used.
|
||||
|
||||
* [Regressions case study](./governance/scalability-regressions-case-studies.md)
|
||||
|
||||
## Kubernetes scalability test frameworks
|
||||
|
||||
Designing and creating frameworks to make scalability and performance testing
|
||||
of Kubernetes easy and available for all contributors.
|
||||
Different frameworks may help in different aspects of scalability testing,
|
||||
enabling making conscious tradeoffs, e.g. cost vs accuracy or real life vs
|
||||
more generalized benchmarking scenarios.
|
||||
|
||||
* [Cluster Loader v2](https://github.com/kubernetes/perf-tests/tree/master/clusterloader2)
|
||||
* [Kubemark](https://github.com/kubernetes/kubernetes/blob/master/cmd/kubemark)
|
||||
|
||||
## Kubernetes scalability and performance tests and validation
|
||||
|
||||
Ensuring that all tests necessary to validate Kubernetes scalability and
|
||||
performance exists (ideally by providing easy-to-use frameworks and working
|
||||
with SIGs to provide them), having engironment and resources to run them.
|
||||
|
||||
Ensuring that tests are being executed according to calendar and ensuring that
|
||||
each official Kubernetes release satisfies all scalability and performance
|
||||
requirements as stated in "Kubernetes scalability" definition.
|
||||
This also includes designing processes to reduce maintenance work and number
|
||||
of scalability and performance regressions:
|
||||
|
||||
* [Processes](https://github.com/kubernetes/community/tree/master/sig-scalability/processes)
|
||||
|
||||
We are in progress to migrating tests to new framework:
|
||||
|
||||
* [Still official tests](https://github.com/kubernetes/kubernetes/tree/master/test/e2e/scalability)
|
||||
* [Soon to be official tests](https://github.com/kubernetes/perf-tests/tree/master/clusterloader2/testing)
|
||||
|
||||
## Kubernetes scalability bottlenecks detection
|
||||
|
||||
Detecting scalability bottlenecks and limitations, documenting them and
|
||||
driving architectural changes to eliminate those (if such are required) in
|
||||
collaboration with other SIGs or directly delegating improvements to
|
||||
individual SIGs, of bottlenecks aren't cross-cutting the whole system.

||||

||||
