# \[AIAS-01] Architecture overview

The target system for the optimization study described in this guide is a Java-based microservice acting as an authentication service for multiple digital applications all running on Kubernetes.

The reference architecture is illustrated by the following diagram. Notice the load testing (JMeter) and monitoring (Elastic APM) tools, respectively used to load the target system and to collect the KPIs used in the optimization study.
