ApsaraDB RDS:Create an RDS MariaDB instance

Prerequisites

RAM users must have the AliyunRDSFullAccess and AliyunBSSOrderAccess permissions. Authorize a RAM user.

Procedure

1. Go to the ApsaraDB RDS instance creation page.

2. Select a Billing Method.

   Billing method	Recommendation	Benefits
   Subscription	For long-term use. Select Subscription and pay upfront.	More cost-effective than pay-as-you-go. Longer duration = higher discount.
   Pay-As-You-Go	For short-term use. Select Pay-As-You-Go for hourly billing. Start with pay-as-you-go, then switch to subscription after confirming the instance fits your needs.	Release anytime to stop billing.

   Note

   The final price is displayed after you complete all configuration steps.

3. Select the Region for the instance.

   For best performance, place the RDS instance in the same region as your ECS instance.

   Note

   • The region cannot be changed after creation. For internal network connectivity, use the same region as your ECS instance.

   • To connect from a non-ECS device, select a nearby region and use a public endpoint.

4. Select the Engine and Storage Type.

   Note

   • Edition only supports High-availability Edition, a primary-secondary architecture suitable for production environments.

   • Product Type currently only supports Standard.

   1. Select the database Engine.

      Select MariaDB.

   2. Select a Storage Type. Storage types.

      Item	Enhanced SSD
      Elastic scaling	Up to 32 TB. Scale up storage without service interruption. Scale instance types up or down and add or remove nodes within minutes. Auto scaling is supported.
      Performance	PL1<PL2<PL3 PL2 provides up to 2x the IOPS and throughput of PL1. PL3 provides up to 20x the IOPS and 11x the throughput of PL1.
      Backup	Backups complete in minutes or seconds. Maximum backup frequency: every 15 minutes.

      Note

      Select Disk Encryption to further protect your data. Cloud disk encryption.

5. Configure instance networking. The Network Type is preset to VPC.

   1. Select a VPC. Use the same VPC as your ECS instance. Instances in different VPCs cannot communicate over the internal network.

   2. Specify whether to Add to Whitelist the VPC CIDR block. This allows ECS instances in the same VPC to access the RDS instance.

      Note

      If you select No, manually configure the IP address whitelist after creation. Configure an IP address whitelist.

6. Select the availability zone, vSwitch, network, and Deployment Method for the instance.

   • Availability zone

     • Availability zones in the same region have no substantive differences.

     • ECS instances perform slightly better when accessing an RDS instance in the same availability zone.

   • vSwitch

     Select an existing vSwitch or click Create vSwitch to create one. Create and manage a vSwitch.

   • Deployment solution

     • Multi-zone Deployment (recommended): Primary and secondary nodes run in different availability zones, providing cross-zone disaster recovery.

       If you select Deployment Method for deployment solution, specify the Zone and Network of Primary Node and Zone and Network of Secondary Node.

     • Single-zone Deployment: The primary and secondary nodes are in the same availability zone.

7. Select an Instance Type.

   1. Select a Category (General-purpose or Dedicated).

      Category	Description	Features
      General-purpose	Shared memory and I/O Dedicated CPU and storage	Lower cost and high price-performance ratio
      Dedicated	Dedicated CPU, memory, storage, and I/O Note The exclusive type provides dedicated use of a physical server's CPU, memory, storage, and I/O.	Better and more stable performance Note The Basic edition does not support dedicated instance types.

   2. Select a specific instance type (CPU cores and memory). Instance types.

8. Select the Capacity.

   The available range depends on your instance type and storage type.

   Minimum increment: 5 GB.

9. (Optional) If you selected Billing Method as the Subscription , you must also set the Duration.

10. Configure additional parameters. Default values work for most use cases.

    Parameter	Description
    Port	The initial port number. Valid values: 1000 to 5999.
    Release Protection	For pay-as-you-go instances, enable Release Protection to prevent accidental release. Enable and disable release protection.
    Resource Group	Select a resource group to organize your instances.
    Instance Name	Custom name for easy identification.
    Tags	Classify and manage instances with tags. Filter instances by tag.

11. In the upper-right corner of the page, select the number of instances to purchase.

    Default: 1. Maximum: 20 per order.

12. Confirm the order details and subscription duration (if applicable), click Confirm Order, and complete the payment. The console displays a Payment Successful or Activated Successfully message.
