Scale operations in Flexible Server

APPLIES TO: Azure Database for PostgreSQL - Flexible Server

This article provides steps to perform scaling operations for compute and storage. You will be able to change your compute tiers between burstable, general purpose, and memory optimized SKUs, including choosing the number of vCores that is suitable to run your application. You can also scale up your storage. Expected IOPS are shown based on the compute tier, vCores and the storage capacity. The cost estimate is also shown based on your selection.

Important

You cannot scale down the storage.

Pre-requisites

To complete this how-to guide, you need:

  • You must have an Azure Database for PostgreSQL - Flexible Server. The same procedure is also applicable for flexible server configured with zone redundancy.

Scaling the compute tier and size

Follow these steps to choose the compute tier.

  1. In the Azure portal, choose your flexible server that you want to restore the backup from.

  2. Click Compute+storage.

  3. A page with current settings is displayed. compute+storage view

  4. You can choose the compute class between burstable, general purpose, and memory optimized tiers. list compute tiers

  5. If you are good with the default vCores and memory sizes, you can skip the next step.

  6. If you want to change the number of vCores, you can click the drop-down of Compute size and click the desired number of vCores/Memory from the list.

    • Burstable compute tier: burstable compute

    • General purpose compute tier: general-purpose compute

    • Memory optimized compute tier: memory optimized compute

  7. Click Save.

  8. You will see a confirmation message. Click OK if you want to proceed.

  9. A notification about the scaling operation in progress.

Scaling storage size

Follow these steps to increase your storage size.

  1. In the Azure portal, choose your flexible server for which you want to increase the storage size.

  2. Click Compute+storage.

  3. A page with current settings is displayed.

click compute+storage 4. The field Storage size in GiB with a slide-bar is shown with the current size.

  1. Slide the bar to your desired size. Corresponding IOPS number is shown. The IOPS is dependent on the compute tier and size. The cost information is also shown.

  1. If you are good with the storage size, click Save.
  2. You will see a confirmation message. Click OK if you want to proceed.
  3. A notification about the scaling operation in progress.
