Pinot S3 Deep Storage - High Availability for Controllers

If i configured S3 to be used for Deep Storage and have a 3 node Zookeeper Cluster, if i want to also have the Controller in High Availability, is that enough, or do I require to use EFS or an HDFS cluster. Wondering in how an actual Production Environment would look like on AWS

Start by reviewing Pinot's S3 deep-storage, controller high-availability, and ZooKeeper deployment guidance, then compare the EFS and HDFS alternatives for AWS production. Done means the issue has a clear, documented production architecture and states whether S3 plus the listed ZooKeeper and controller setup is sufficient.
