# Apache YuniKorn - A Universal Scheduler
Apache YuniKorn is a light-weight, universal resource scheduler for container
orchestrator systems.
-It was created to achieve fine-grained resource sharing for various workloads
efficiently on a large scale, multi-tenant, and cloud-native environment.
YuniKorn brings a unified, cross-platform, scheduling experience for mixed
workloads that consist of AI, Machine Learning, stateless batch workloads and
stateful services.

YuniKorn's architecture design also allows adding different shim layer and
adopt to different ResourceManager implementation including Apache Hadoop YARN,

## Deployment model
YuniKorn can be deployed with
[helm-charts](https://artifacthub.io/packages/helm/yunikorn/yunikorn) on an
existing K8s cluster. It can be deployed with or without the admission
controller. When the admission controller is enabled, YuniKorn will be the
primary scheduler that takes over the resource scheduling (the admission
controller runs a mutation webhook that automatically mutates pod spec's
schedulerName to yunikorn); when it is disabled, user needs to manually change
the schedulerNa [...]
