# \[AIAB-02] Create the system and its components

Akamas provides an out-of-the-box optimization pack called Web Application that comes very handy for modeling typical web applications, as it includes metrics such as `transactions_throughput` and `transaction_response_time` which you will use in this guide to define the optimization goal and analyze the optimization results. These metrics will be gathered from JMeter, thanks to Akamas out-of-the-box Prometheus telemetry provider.

Let's create the system and its components.

The file `system.yaml` contains the following definition for our system:

```yaml
name: konakart
description: The konakart eCommerce shop
```

Run the command to create it:

```bash
akamas create system system.yaml
```

Now, install the Web Application optimization pack from the UI:

These metrics will be gathered from JMeter, thanks to Akamas out-of-the-box Prometheus telemetry provider.

You can now create the component modeling of the Konakart web application.

The file `comp_konakart.yaml` defines the component as follows:

```yaml
name: konakart
description: The konakart web application
componentType: Web Application
properties:
  prometheus:
    instance: jmeter
    job: jmeter
```

As you can see, this component contains some custom properties, *instance* and *job*, under the *prometheus* group. These properties are used by the Prometheus telemetry provider as values for the corresponding instance and job labels in the Prometheus queries to collect metrics for the correct entities. You will configure the Prometheus integration in the next sections.

You can now run the command to create the component:

```bash
akamas create component comp_konakart.yaml konakart
```

You can now explore the result of your system modeling in the UI. As you can see, your `konakart` component is now populated with all the typical metrics of a web application:
