 ## Technical Overview
 
-In this solution, log messages are collected by the Fluent Bit
-pods that are part of the standard logging solution and that are deployed 
-cluster-wide by using a Kubernetes DaemonSet. These Fluent Bit pods can 
-parse and process log messages from all SAS Viya components, including 
-third-party products. As a result, log messages are handled consistently, 
-regardless of the original source.
