## Realistic application benchmark
For realistic application benchmarks we use [IBM's BluePerf](https://github.com/blueperf).
Acmeair (a.k.a, BluePerf) is a customer-like microservices application implemented in Java. This application runs on WebSphere Liberty and simulates the operations of a fictitious airline.
The results for each build are published automatically on the [Istio Regression Patrol](https://ibmcloud-perf.istio.io/regpatrol/) site.
Acmeair is composed by the following microservices:
* **Flight Service** retrieves flight route data. It is called by the Booking service to check miles for the rewards operations (Acmeair customer fidelity program).
* **Customer Service** stores, updates, and retrieves customer data. It is invoked by the Auth service for login and by the Booking service for the rewards operations.
* **Booking Service** stores, updates, and retrieves booking data.
* **Auth Service** generates JWT if the user/password is valid.
* **Main Service** primarily consists of the presentation layer (web pages) that interact with the other services. This allows the user to interact directly with the application via browser, but it is not exercised during the load test.
The diagram below represents the different pods/containers of the application in the Kubernetes/Istio environment:

The following table shows the transactions that are driven by the script during the regression test and the approximate distribution of the requests:
