> You can choose between SMTP and Sendgrid as the mailer type. If you want to use a Gmail account as the SMTP server, follow the steps below.

<Note>
  To use a Gmail account as an SMTP server, ensure the following settings are applied:

  * Enable 2-Step Verification
  * If the administrator of an organizational account has disabled the App Passwords feature due to security policies, request the administrator to enable it

    * **Email sender**: The sender's email address
    * **Type**: SMTP
    * **SMTP Host**: smtp.gmail.com
    * **SMTP Port**: 465
    * **SMTP Username**: The Gmail address used for SMTP setup
    * **SMTP Password**: App password
    * **Secure Connection**: Enabled
  </Step>

## Resource Profile Management

<Frame>
  <img className="block rounded-md" src="https://files.cloudtype.io/ale-docs/operations/images/en/07_11.png" />
</Frame>

> You can allocate predefined resource sets to spaces. Configure resource profiles as described below and [easily assign resources by applying resource profiles to spaces.](/en/operations/spaces#apply-a-resource-profile)

<Steps>
  <Step title="Set Profile Name and Display Name">
    <Frame>
      <img className="block rounded-md" src="https://files.cloudtype.io/ale-docs/operations/images/en/07_19.png" />
    </Frame>

    Click `Add` in the **Resource Quota** section and enter the profile name and the display name.
  </Step>

  <Step title="Configure Resource Values for On-Demand / Spot Types">
    <Frame>
      <img className="block rounded-md" src="https://files.cloudtype.io/ale-docs/operations/images/en/07_12.png" />
    </Frame>

    Configure resource values for each type. You can use only one type or mix both. **If no value is entered, the placeholder value will be applied.** Key fields include:

    * **vCPU / Memory / Disk**: Total resources allocated to the space
    * **Max vCPU / Memory / Disk**: Maximum resources per service
    * **Max Running**: Maximum number of services that can be deployed
    * **Max Replica**: Maximum number of replicas per service
    * **Node Group**: Specify `on-demand` or `spot`. See details below.

    <AccordionGroup>
      <Accordion title="On-Demand / Spot" defaultOpen={true}>
        > `ale` supports resource allocation based on instance types for efficient resource management. Specify `on-demand` or `spot` in the Node Group field to allocate resources accordingly.

        <Tip>
          Even if the cluster's worker nodes consist only of on-demand instances or if spot resources are unavailable, `ale` can still deploy services labeled as spot. These services will run on on-demand instances but will retain the spot label.
        </Tip>

        <Note>
          Services deployed with spot resources can be removed at once using the [Bulk Remove Spot Resources](/en/operations/spaces#bulk-remove-spot-resources) feature. For temporary services, deploying with spot resources can help manage cloud costs efficiently by using this feature.

        </Note>

        <Info>
          The availability and pricing policies for on-demand and spot instances differ by CSP. Refer to the following links for more information:

          * [Amazon EC2 Spot](https://aws.amazon.com/ec2/spot/details/)
          * [GCP Spot VM](https://cloud.google.com/compute/docs/instances/spot)

    * **Domain**: Number of allowed custom domains (set to 0 to disable)
    * **Max Services**: Maximum number of deployable services (including on-demand and spot)
    * **Max Members**: Maximum number of team members allowed in the space
    * **Max Projects**: Maximum number of projects in the space
    * **Services per Environment**: Maximum services per environment(namespace)
    * **Others**: If the placeholder value is 0, it will be applied as unlimited.
  </Step>
</Steps>

<Tip>
  When a space is created, the `Default` profile is applied by default.
