For server specifications supported by Cloud DB for MySQL, see [**Services > Database > Cloud DB for MySQL**](https://www.ncloud.com/product/database/cloudDbMysql) in the portal. ### Specification details The server operating system, operating system disk size, storage engine, and licensing information are as follows: | Item | Platform | Description | | --- | --- | --- | | Server operating system | VPC | - Rocky 8.10 - CentOS 7.8 (before October 17, 2024) | | Classic | CentOS 7.8 | | Operating system disk size | VPC, Classic | 50 GB (not changeable) | | Storage engine | VPC, Classic | InnoDB, Memory | | License | VPC, Classic | [General Public License](https://www.mysql.com/about/legal/licensing/oem/) | ## Service limits when changing server specifications The type of an operational MySQL Server that has been created and is in operation cannot be changed, but the available memory size can be changed at any time using the **Change specifications** feature in the console **DB Server** menu. When creating a server with G3 in the Korea Region, you can change the server type. For information on how to change the available memory size, see [DB Server](/docs/en/database-database-5-2#mysql-server-%EC%8A%A4%ED%8E%99-%EB%B3%80%EA%B2%BD). However, a few service limits exist when changing the server specifications. Make sure you are aware of the following service limits before making any changes to the server specifications: - They can only be changed within the same type. - If configured with more than 2 servers (using high availability and using Read Replica), change all to the same specification. - The server restarts upon completion of the change. Therefore, the service may possibly be affected. ## Server redundancy configuration Cloud DB for MySQL supports the high availability (HA) feature. Automatic Failover to the Standby Master Server if the operating Master Server fails and normal service is not possible. When creating MySQL Server in the NAVER Cloud Platform console, you can choose whether to use high availability (HA) or not, and the server configuration depends on whether to use it. Caution Failover may take several minutes to complete. ## Pricing information Cloud DB for MySQL uses a pay-as-you-go pricing plan. For detailed description of Cloud DB for MySQL's pricing standard, see **Portal > Services > Database > Cloud DB for MySQL**. - [**Portal > Services > Database > Cloud DB for MySQL**](https://www.ncloud.com/product/database/cloudDbMysql)
