ApsaraDB RDS:Create an ApsaraDB RDS for MariaDB instance

New version

1. Go to the new version of the ApsaraDB RDS buy page.

2. Configure the Billing Method parameter.

   Billing method	Description	Benefit
   Subscription	A subscription instance is an instance for which you pay an upfront fee. If you want to use an instance for a long period of time, we recommend that you select the Subscription billing method. If you select the subscription billing method, configure the Subscription Duration parameter in the lower part of the page.	In most cases, the subscription billing method is more cost-effective than the pay-as-you-go billing method for long-term usage. Alibaba Cloud provides lower prices for longer subscription durations.
   Pay-as-you-go	You are charged on an hourly basis for a pay-as-you-go RDS instance based on your actual resource usage. If you want to use an RDS instance for a short period of time, we recommend that you select the pay-as-you-go billing method. You can create a pay-as-you-go RDS instance. After you confirm that the created RDS instance meets your business requirements, you can change the billing method of the RDS instance to subscription.	You can release a pay-as-you-go RDS instance based on your business requirements. The billing cycle of a pay-as-you-go RDS instance immediately stops after you release the instance.

   Note

   You can view the price in the lower-right corner of the page. The price is displayed only after you configure all required parameters.

3. Configure the Region parameter.

   We recommend that you create the RDS instance in the same region as the Elastic Compute Service (ECS) instance. If the RDS instance and the ECS instance reside in different regions, these instances cannot communicate over an internal network. As a result, these instances cannot deliver optimal performance.

   Note

   • After an RDS instance is created, you cannot change the region of the RDS instance. If an ECS instance connects to an RDS instance over an internal network, make sure that the RDS instance and the ECS instance reside in the same region.

   • If your application is deployed on an on-premises server or computer, we recommend that you select a region that is in close proximity to the on-premises server or computer. This way, you can use the public endpoint of the RDS instance to connect to the RDS instance from your application.

4. Configure the Database Engine and Storage Type parameters.

   Note

   • You can set the Edition parameter only to High-availability Edition. In RDS High-availability Edition, your database system consists of a primary RDS instance and a secondary RDS instance. These instances work in a high availability architecture. RDS High-availability Edition is suitable for more than 80% of production environments.

   • You can set the Product Type parameter only to Standard.

   1. Configure the Database Engine parameter.

      Select MariaDB.

   2. Configure the Storage Type parameter. For more information, see Storage types.

      Item	ESSD
      Scalability	You can increase the storage capacity up to 32 TB. No transient connections occur during storage capacity expansion. You can upgrade, downgrade, create, or release the RDS instance within minutes. Automatic storage expansion is supported.
      Performance	PL1<PL2<PL3 A performance level 2 (PL2) Enterprise SSD (ESSD) delivers twice the IOPS and throughput of a PL1 ESSD. An ESSD of PL3 delivers IOPS that is up to 20 times the IOPS delivered by an ESSD of PL1. An ESSD of PL3 also delivers throughput that is up to 11 times the throughput delivered by an ESSD of PL1.
      Backup	A backup can be completed within minutes or seconds. The highest backup frequency is once every 15 minutes.

      Note

      You can select Cloud Disk Encryption to ensure data security. For more information, see Configure the cloud disk encryption feature.

5. Configure the Network Type parameter. The Network Type parameter is fixed as VPC.

   1. Configure the VPC parameter.

      We recommend that you select the virtual private cloud (VPC) in which your ECS instance resides for the RDS instance. If the RDS instance and the ECS instance reside in different VPCs, these instances cannot communicate over an internal network.

   2. Configure the Add to Whitelist parameter to specify whether to add the CIDR block of the selected VPC to a whitelist of the RDS instance.

      If you set this parameter to Yes, the ECS instances that reside in the selected VPC can access the RDS instance.

      Note

      If you set the Add to Whitelist parameter to No, you can configure a whitelist after the RDS instance is created. For more information, see Configure an IP address whitelist.

6. Select a zone and vSwitch and then configure the Deployment Method parameter.

   • Select a zone.

     • No significant differences exist between the zones in the same region.

     • If the RDS instance resides in the same zone as the ECS instance that you want to connect, these instances can deliver optimal performance. If the RDS instance and the ECS instance reside in different zones in the same region, the performance of these instances slightly decreases.

   • Select a vSwitch.

     Select an existing vSwitch or click Create vSwitch. For more information, see Create and manage a vSwitch.

   • Select a deployment method.

     • Multi-zone Deployment: This is the recommended deployment method. The primary RDS instance and the secondary RDS instance reside in different zones to provide zone-disaster recovery.

       If you set the Deployment Method parameter to Multi-zone Deployment, you must configure the Zone and Network of Primary Node and Zone and Network of Secondary Node parameters.

     • Single-zone Deployment: The RDS instance and the secondary RDS instance reside in the same zone.

7. Configure the Instance Type parameter.

   1. Configure the Category parameter. You can select General-purpose or Dedicated.

      Instance type	Description	Benefit
      General-purpose	A general-purpose RDS instance occupies all the allocated memory and I/O resources. A general-purpose RDS instance shares CPU and storage resources with the other general-purpose RDS instances that are deployed on the same host.	RDS instances of the general-purpose instance type are cost-effective.
      Dedicated	A dedicated RDS instance occupies all the allocated CPU, memory, storage, and I/O resources. Note The dedicated host instance family is the highest configuration of the dedicated instance family. A dedicated host RDS instance exclusively occupies all the CPU, memory, storage, and I/O resources of the host on which the RDS instance is deployed.	A dedicated RDS instance delivers higher performance and higher stability. Note An RDS instance that runs RDS Basic Edition does not support the dedicated instance family.

   2. Configure detailed specifications, including CPU cores and memory capacity.

      Note

      For more information about instance types, see Instance types.

8. Configure the Storage Capacity parameter.

   The value range of the storage capacity varies based on the instance type and storage type that you select.

   You can adjust the storage capacity at a step size of 5 GB.

9. Optional. If you set the Billing Method parameter to Subscription, configure the Subscription Duration parameter based on your business requirements.

   • Baseline Price: The list price of a subscription RDS instance without any discounts.

   • Preferential Monthly Fee: The monthly price that is calculated based on the baseline price of a subscription RDS instance.

     Note

     The fee is calculated based only on the list price of the RDS instance, which does not include coupons or promotions.

   • Price: You can move the pointer over View Details on the right side of the page to view the estimated total price that is calculated based on the subscription duration and the baseline price of the RDS instance.

10. Configure other custom parameters. If you do not have special business requirements, you can retain the default values of these parameters.

    Parameter	Description
    Port	You can initialize the port when you create an RDS instance. Valid values: 1000 to 5999.
    Release Protection	If you set the Billing Method parameter to Pay-as-you-go, you can select Release Protection to prevent the RDS instance from being released due to unintended operations. For more information, see Enable or disable the release protection feature.
    Resource Group	Use the default resource group or select a custom resource group based on your business requirements.
    Instance Description	Enter a description for easy identification.
    Privileged Account	You can create a privileged account when you create the RDS instance. If you select Configure Later, you can create a privileged account after the RDS instance is created. Note Each RDS instance can have only one privileged account. The privileged account cannot be deleted. For more information about privileged accounts and how to create privileged accounts, see Create a database and an account.

11. In the upper-right corner of the page, configure the Quantity parameter.

    The default value is 1. You can purchase up to 20 instances at a time. Specify the number of instances based on your business requirements.

12. Confirm the configurations, quantity, and subscription duration of the RDS instance, read and select ApsaraDB RDS Terms of Service, click Pay Now, and then complete the payment. You must configure the Subscription Duration parameter only when you select the subscription billing method for the RDS instance. The Congratulations or The service is activated message is displayed in the ApsaraDB RDS console.

    Note

    If you select the subscription billing method for the RDS instance, we recommend that you select Enable Auto-renewal. This prevents interruptions on your application even if you forget to renew the RDS instance.

    The auto-renewal cycle is one month for monthly subscription and one year for yearly subscription. The actual auto-renewal cycle in the order prevails. You can disable auto-renewal at any time. For more information, see Use the auto-renewal feature.

13. View the RDS instance.

    Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance based on the Creation Time parameter.
