Which feature does the Splunk REST API provide?

The feature that the Splunk REST API provides is focused on reducing overhead related to maintaining machines. By utilizing the REST API, administrators and developers can interact with Splunk services programmatically, which allows for efficient management and automation of tasks without needing to handle the underlying infrastructure directly. This capability can streamline operations, reduce the complexity of managing multiple instances, and enable better resource utilization.

Automating queries, data inputs, and system configurations through the API means that organizations can save time and decrease the manual workload on IT staff, which in turn lowers the operational overhead in maintaining multiple machines. This is especially beneficial in cloud environments where resource management can become cumbersome if performed manually.

A consistent internet connection is indeed important for the proper functioning of cloud services, but this concept does not describe a feature of the REST API itself. Similarly, any impact on data speed or transmitted data security would depend on various factors surrounding how the API is utilized rather than being direct features it provides.
