# Load Balancer Flavor Profiles

> Create and manage capacity tier definitions that users select when provisioning Xloud Load Balancer instances.

## Overview

Flavor profiles define the compute capacity and topology configuration allocated to load
balancing appliances. Administrators create named flavors that users select at load balancer
provisioning time. Flavors abstract provider-specific settings into human-readable capacity
tiers — e.g., `standard`, `ha`, and `high-performance`.

<Warning>
  **Administrator Access Required** — This operation requires the `admin` role. Contact your
  Xloud administrator if you do not have sufficient permissions.

## Flavor Architecture

| Concept            | Description                                                                               |
| ------------------ | ----------------------------------------------------------------------------------------- |
| **Flavor Profile** | Provider-specific settings template (topology, compute class, etc.)                       |
| **Flavor**         | Named, user-visible tier based on a flavor profile. Users select flavors at provisioning. |

A flavor profile is always associated with a specific provider. Multiple flavors can
reference the same profile.

## Create a Flavor Profile

<Steps titleSize="h3">
  <Step title="Create a flavor profile" icon="settings">
    A flavor profile wraps provider-specific settings:

    ```bash title="Create standard single-topology profile" theme={null}
    openstack loadbalancer flavorprofile create \
      --name standard-profile \
      --provider amphora \
      --flavor-data '{"loadbalancer_topology": "SINGLE"}'
    ```

    ```bash title="Create HA active-standby profile" theme={null}
    openstack loadbalancer flavorprofile create \
      --name ha-profile \
      --provider amphora \
      --flavor-data '{"loadbalancer_topology": "ACTIVE_STANDBY"}'
    ```
  </Step>

  <Step title="Create named flavors for users" icon="package">
    Expose profiles as named flavors:

    ```bash title="Create standard flavor" theme={null}
    openstack loadbalancer flavor create \
      --name standard \
      --flavorprofile standard-profile \
      --description "Standard single-instance load balancer" \
      --enable
    ```

    ```bash title="Create HA flavor" theme={null}
    openstack loadbalancer flavor create \
      --name ha \
      --flavorprofile ha-profile \
      --description "High-availability active-standby load balancer" \
      --enable
    ```
  </Step>

  <Step title="Verify flavors are available" icon="circle-check">
    ```bash title="List available flavors" theme={null}
    openstack loadbalancer flavor list
    ```

    <Check>Flavors appear in the list with status **enabled** — you can now select them when creating a load balancer.</Check>
  </Step>
</Steps>

## Flavor Profile Settings Reference

| Setting                 | Provider | Description                                              |
| ----------------------- | -------- | -------------------------------------------------------- |
| `loadbalancer_topology` | amphora  | `SINGLE` or `ACTIVE_STANDBY`                             |
| `compute_flavor`        | amphora  | Nova flavor for the appliance instance                   |
| `amp_image_tag`         | amphora  | Tag identifying the appliance image in the Image Service |
| `availability_zone`     | amphora  | Restrict appliance placement to a specific AZ            |

## Manage Flavors

<CodeGroup>
  ```bash title="List all flavors" theme={null}
  openstack loadbalancer flavor list
  ```

  ```bash title="Show flavor details" theme={null}
  openstack loadbalancer flavor show standard
  ```

  ```bash title="Disable a flavor (prevents new LBs from using it)" theme={null}
  openstack loadbalancer flavor set standard --disable
  ```

  ```bash title="Delete a flavor" theme={null}
  openstack loadbalancer flavor delete standard
  ```

  ```bash title="List flavor profiles" theme={null}
  openstack loadbalancer flavorprofile list
  ```
</CodeGroup>

<Warning>
  Disabling a flavor prevents new load balancers from using it but does not affect
  existing load balancers. Deleting a flavor profile that is referenced by a flavor
  will fail — delete the flavor first.
</Warning>

## Recommended Flavor Set

For most production deployments, provide at least two flavors:

| Flavor Name | Profile         | Use Case                                         |
| ----------- | --------------- | ------------------------------------------------ |
| `standard`  | Single topology | Development, testing, non-critical workloads     |
| `ha`        | Active-standby  | Production workloads requiring high availability |
