 ## What is an Operator?
 
-An Operator is a [Kubernetes custom controller]( https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources#custom-controllers) which extends the native K8s API. Refer to the article [Redis Enterprise K8s Operator-based deployments – Overview]({{< relref "/platforms/kubernetes/concepts/operator.md" >}}).

-- Operators are a K8s standards while Helm is a proprietary tool
-    - Using Operators means the better packaging for different Kubernetes deployments and distributions as Helm is not supported in a straightforward way everywhere
-- Operators allow full control over the Redis Enterprise Cluster lifecycle
-    - We’ve experienced difficulties managing state and lifecycle of the application through Helm as it essentially only allows to determine the resources being deployed, which is a problem when upgrading and evolve the Redis Enterprise Cluster settings
-- Operators support advanced flows which would otherwise require using an additional 3rd party
