### Cluster Federation

#### [alpha] Federated Jobs

Federated Jobs that are automatically deployed to multiple clusters
are now supported. Cluster selection and weighting determine how Job
parallelism and completions are spread across clusters. Federated Job
status reflects the aggregate status across all underlying cluster
jobs.

#### [alpha] Federated Horizontal Pod Autoscaling (HPA)

### Parallele Hamburger

Stellen wir uns jetzt vor, dass es sich hierbei nicht um „nebenläufige Hamburger“, sondern um „parallele Hamburger“ handelt.

Sie gehen los mit Ihrem Schwarm, um paralleles Fast Food zu bekommen.

Sie stehen in der Schlange, während mehrere (sagen wir acht) Kassierer, die gleichzeitig Köche sind, die Bestellungen der Leute vor Ihnen entgegennehmen.

* gce/kube-down: Parallelize IGM deletion, batch more ([#27302](https://github.com/kubernetes/kubernetes/pull/27302), [@zmerlynn](https://github.com/zmerlynn))

* Create a new Deployment in kube-system for every version. ([#23512](https://github.com/kubernetes/kubernetes/pull/23512), [@Q-Lee](https://github.com/Q-Lee))
* Use SCP to dump logs and parallelize a bit. ([#22835](https://github.com/kubernetes/kubernetes/pull/22835), [@spxtr](https://github.com/spxtr))

* Replace Parallelize with function ParallelizeUntil and formally deprecate the Parallelize. ([#68403](https://github.com/kubernetes/kubernetes/pull/68403), [@wgliang](https://github.com/wgliang))

- Removed the function Parallelize, please convert to use the function ParallelizeUntil. ([#76595](https://github.com/kubernetes/kubernetes/pull/76595), [@danielqsj](https://github.com/danielqsj))
