Where is it recommended to install an ES search head?

The recommended option for installing an Enterprise Security (ES) search head is on any Splunk server. The rationale behind this recommendation is rooted in the flexibility offered by Splunk's architecture. A search head can be deployed on various types of servers, allowing organizations to optimize their resources according to their specific environment and infrastructure.

Deploying the search head on any Splunk server enables organizations to centralize search capabilities and allows for scalability. It also supports maintaining the performance necessary for processing searches efficiently, regardless of whether the server is dedicated or utilized for other Splunk functionalities.

Furthermore, this choice does not impose limitations on the server type, offering greater deployment flexibility based on the organization’s operational needs. This makes it a versatile solution for conducting security searches across the data ingested into Splunk, regardless of the specific install base or type of Splunk server in use.
