+---
+
+In an organization, a Pulsar instance provides services to multiple teams. 
When organizing the resources across multiple teams, you want to make a 
suitable isolation plan to avoid the resource competition between different 
teams and applications and provide high-quality messaging service. In this 
case, you need to take resource isolation into consideration and weigh your 
intended actions against expected and unexpected consequences.
+
+To enforce resource isolation, you can use the Pulsar isolation policy, which 
allows you to allocate resources (**broker** and **bookie**) for the namespace.
+
+## Broker isolation
+
+In Pulsar, when namespaces (more specifically, namespace bundles) are assigned 
dynamically to brokers, the namespace isolation policy limits the set of 
brokers that can be used for assignment. Before topics are assigned to brokers, 
you can set the namespace isolation policy with a primary or a secondary regex 
to select desired brokers.
+
+You can set a namespace isolation policy for a cluster using one of the 
following methods. 
+
+<!--DOCUSAURUS_CODE_TABS-->
+
+<!--Admin CLI-->
+
+```
+pulsar-admin ns-isolation-policy set options
+```
+
+For more information about the command and descriptions, see 
[here](http://pulsar.apache.org/tools/pulsar-admin/2.8.0-SNAPSHOT/#-em-set-em-).

Review comment:
       Thanks for your suggestion. While the Pulsar website itself (Pulsar 
Admin CLI doc) does not contain this command and the information on the "Pulsar 
Admin CLI" page is far behind from pulsar-admin where contains the latest 
information.
   
   Seems that there was an issue (create automatic workflow) to sync contents 
from pulsar-admin to the Pulsar website, but no more updates for a long time. I 
think right now the best choice is to point users to get the latest information 
and we can update the link once we have a better option.
