# \[AIAS-03] Architecture overview

The [Online Boutique application](https://github.com/GoogleCloudPlatform/microservices-demo) is a cloud-native microservices application implemented by Google as a demo application for Kubernetes. It is a web-based sample, yet a fully-fledged, e-commerce application.

To stress the application and validate Akamas AI-based configurations under load, the setup includes the Locust load testing tool which simulates user activity on the application.

Prometheus is used to collect metrics related to the application (throughput and response times) as well as Kubernetes infrastructure (container resource usage).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.akamas.io/quick-guides/quick-guides-akamas-in-a-sandbox/aias-03-guide-create-a-study-to-optimize-k8s-microservices-costs-using-the-akamas-cli/aias-03-architecture-overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
