+
+What is an Operator?
+--------------------
+
+An operator is a standard mechanism that extends the control plane of 
+|k8s| to managing custom |k8s| resources. Because each operator is 
+built for its own Custom Resources (CRs), it can contain logic that 
+addresses the type of service that the operator is built for. For the 
+|k8s-op-short|, the operator includes the logic for the deployment of 
+MongoDB Server and Ops Manager instances.
+
+Each CR used by the |k8s-op-short| represents an element of a MongoDB 
+Server deployment in |k8s|, and has options for customizing that part
+of the deployment. Once you configure these objects in the |k8s| 
+deployment, the operator builds native |k8s| objects, such as Stateful 
+Sets that are necessary to create Pods according to your specified 
+requirements for MongoDB Servers. The operator also facilitates 
+configuration of MongoDB Server features, such as database backups, 
+through interaction with |cloud| or |onprem|.
+
+Why should I run MongoDB Server and MongoDB Enterprise Advanced in |k8s|?
+--------------------------------------------------------------------------
+
+When you deploy MongoDB Server or MongoDB Enterprise Advanced in |k8s| 
+through the |k8s-op-full|, your deployments can benefit from the 
+resilience and simple orchestration that |k8s| provides.
+
+The only supported way to deploy MongoDB Enterprise Advanced in |k8s| is 
+through the |k8s-op-full|. The |k8s-op-full| simplifies your daily 
+workflows and makes it easier for MongoDB technical support staff to 
+assist you when needed.
+
+Which |k8s| platforms are supported for MongoDB Server deployments?
+-------------------------------------------------------------------------
+
+MongoDB Server supports any platform that builds upon native |k8s| 
+without changing the default logic or behavior. In practice, this means
+that MongoDB Server supports any |k8s| platform 
+`certified by the Cloud Native Computing Foundation <https://www.cncf.io/certification/software-conformance/>`_. 
+To learn more, see 
+:ref:`MongoDB Kubernetes Operator Compatibility <k8s-compatibility>`.
+
+How many deployments can |k8s-op-full| support?
+-----------------------------------------------
+
+|k8s-op-short| can support up to 50 deployments. However, changes made
+to large numbers of deployments at the same time result in long 
+reconciliation times. To avoid prolonged reconciliation times, limit a
+given |k8s-op-short| instance to 20 deployments. To learn more, 
+see the :ref:`production notes <deploy_recommended-number-sets>`.
+
+Should I run MongoDB Server in |k8s| in the same cluster as the application using it?
+--------------------------------------------------------------------------------------
+
+To help minimize latency, consider colocating your database and 
+applications on the same |k8s| cluster if your deployment architecture
+allows this.
+
+Can I deploy MongoDB Server across multiple |k8s| clusters?
+-----------------------------------------------------------
+
+This feature is available in Beta releases, as described in 
+:ref:`Deploy MongoDB Resources on Multiple Kubernetes Clusters <multi-cluster>`.
+To learn more, 
+`contact Support <https://cloud.mongodb.com/links/support>`_.
