How to scale up a Redis™ Database Instance

Published on 11 July 2022

If you want to scale up the size of your Redis™ Database Instance, you can edit your node settings to either:

  • scale vertically: upgrade to a bigger node type to allow increased traffic for the same endpoint.
  • scale horizontally: add more nodes to your Database Instance to increase your number of endpoints and distribute cache. This setting is only available for Database Instances in cluster mode.

How to scale vertically

Requirements:
  1. Click Redis™ under Managed Databases on the side menu. A list of your Database Instances displays.

  2. Click the database name or «See more Icon» > More info to access the Database Instances information page.

  3. Scroll down the page to the Node Settings section.

  4. Click Scale vertically. A pop-up appears.

  5. Select a new node type from the drop-down.

  6. Check the details of the estimated cost and click Validate.

    You can view the details of your new node type in the Database Instance information page.

How to scale horizontally

Requirements:
  1. Click Redis™ under Database on the side menu. A list of your Database Instances displays.

  2. Click the database name or «See more Icon» > More info to access the Database Instance information page.

  3. Scroll down the page to the Node Settings section.

  4. Click Scale horizontally. A pop-up appears.

  5. Set a new total number of nodes.

    Note:

    The new total number of nodes has to be bigger than your current number of nodes. You can add up to 6 nodes.

  6. Check the details of the estimated cost and click Validate.

    Note:

    Scaling the number of nodes in your Database Instance can take up to several minutes depending on the number of nodes you select.

    Note:

    When TLS is enabled, scaling your Database Instance horizontally won’t generate a new SSL certificate with additional IPs. You have to manually renew the cluster SSL certificate in order to get the new IPs.

You can check your new number of nodes in the Database Instance information page under Node configuration.
