title: Is Hazelcast Clustering recommended for a WSO2 Active-Active Deployment?
body: <p>I have an Active-Active Deployment of WSO2 API Manager. I don't know if I should enable Hazelcast Clustering, because:</p>
  
  <p>A) On one hand, in the <a href="https://docs.wso2.com/display/AM250/Configuring+an+Active-Active+Deployment" rel="nofollow noreferrer">link of official documentation that I followed to deploy</a>, Hazelcast doesn't appear.</p>
  
  <p>B) On the other hand, this <a href="https://docs.wso2.com/display/AM210/Working+with+Hazelcast+Clustering#WorkingwithHazelcastClustering-EnablingHazelcastclustering" rel="nofollow noreferrer">link of official documentation</a> says that backend throttling limits will not be shared across the cluster when Hazelcast clustering is disabled (and I of course want that backend throttling limits are shared across the cluster!). But that link is under section "Distributed Deployment", and I haven't a "Distributed Deployment". As I said, I have a "Active-Active Deployment", so I don't know if I should follow that link and install Hazelcast.</p>
