Installing the Index Search Server in Cloud Mode
This mode of installation is explained in this section using an example. The following example installs the index search server in cloud mode with three Zookeeper nodes and two Solr nodes.
It is important that you install and configure the Zookeeper nodes first and then proceed with installing the index search server in high availability mode.
* 
PTC strongly recommends the use of defense-in-depth in the deployment of the Zookeeper nodes by making this application available only within the internal corporate network and never exposed to the internet.
