ApsaraDB RDS:[EOS/Discontinuation] End of sale for the standard SSD storage type for specific database engines in ApsaraDB RDS from July 01, 2022

Specific database engines and end-of-sale dates

Impacts and suggestions

• When you purchase an ApsaraDB RDS instance that runs one of the following database engines, you cannot select the standard SSD storage type:

  • MySQL

  • PostgreSQL

  • MariaDB

  • SQL Server

  Note

  The standard SSD storage type is gradually phased out. You may still be able to select the standard SSD storage type after July 01, 2022. However, we recommend that you select the ESSD storage type.

• If your existing RDS instances use the standard SSD storage type, you can continue to use the configured standard SSDs. However, we recommend that you upgrade standard SSDs to PL1 ESSDs to experience better read and write performance.

  Note

  When you upgrade the storage type, you are charged a specific fee. The fee varies based on the region in which your RDS instance resides. You can view the fee when you perform the upgrade.
