ApsaraDB RDS:Create an ApsaraDB RDS for MariaDB instance

Select a billing method

Select a Billing Method.

Select a region

Select the Region where you want to create the instance.

• Same region as your ECS instance: Place the RDS instance in the same region as your Elastic Compute Service (ECS) instance to enable internal network connectivity and optimal performance.

• No ECS instance: Select a region close to your users and connect through the public endpoint.

Select a database engine and storage type

The Edition is automatically set to High-availability Edition, which deploys a primary node and a secondary node in a classic high-availability architecture. The Product Type is set to Standard.

1. For Database Engine, select MariaDB.

2. Select a Storage Type. The available storage type for MariaDB is ESSD. For more information, see Storage types.

   Aspect	ESSD
   Scalability	Up to 32 TB. No transient connections occur during storage expansion. Supports automatic storage expansion. Upgrade, downgrade, add, or remove nodes in minutes.
   Performance	Three performance levels: PL1 < PL2 < PL3. A PL2 ESSD delivers up to 2x the IOPS and throughput of a PL1 ESSD. A PL3 ESSD delivers up to 20x the IOPS and 11x the throughput of a PL1 ESSD.
   Backup	Backups complete in minutes or seconds. The highest backup frequency is once every 15 minutes.

3. (Optional) Select Cloud Disk Encryption for additional data protection. For more information, see Disk encryption.

Configure the network

The network type is fixed to VPC.

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

2. Specify whether to Add to Whitelist. If you enable this option, ECS instances in the same VPC can access the RDS instance.

Configure zones and deployment method

1. Zone: Select a zone. An ECS instance achieves slightly better performance when it accesses an RDS instance in the same zone, but the performance difference across zones within the same region is minor.

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

3. Deployment Method:

   Note Multi-zone Deployment is only available for subscription instances. Pay-as-you-go instances support Single-zone Deployment only.

   Method	Description
   Multi-zone Deployment (recommended)	The primary and secondary nodes are deployed in different zones within the same region. Provides cross-zone disaster recovery. Specify the Zone and Network of Primary Node and Zone and Network of Secondary Node.
   Single-zone Deployment	The primary and secondary nodes are deployed in the same zone.

Select an instance type

1. Select a Category.

   Note Dedicated Host is the top-tier configuration of the Dedicated category. It exclusively occupies all CPU, memory, storage, and I/O resources of a physical server.

   Category	Resources	When to use
   General-purpose Instance Types	Shared memory and I/O. Dedicated CPU and storage.	Cost-effective choice for most workloads.
   Dedicated Instance Types	Dedicated CPU, memory, storage, and I/O.	Better and more stable performance for demanding workloads.

2. Select the specifications (CPU cores and memory). For a full list, see Instance types.

Select the storage capacity

Select the Storage Capacity. The available range depends on your instance type and storage type.

Storage capacity is adjustable in increments of at least 5 GB.

Set the subscription duration (subscription only)

If you selected Subscription as the billing method, configure the Subscription Duration in the upper-right corner of the page.

Longer subscription durations offer lower prices. Hover over View Details next to the price to see a breakdown.

Configure optional parameters

The default values work for most use cases.

Set the quantity and confirm

1. In the upper-right corner of the page, set the number of instances to purchase. The default is 1. You can purchase up to 20 instances at a time.

2. Review the order information, quantity, and subscription duration (for subscription instances). Click Confirm Order and complete the payment. The console displays a Payment successful or Service activated message.

Verify the instance

Go to the Instances page. In the top navigation bar, select the region of the instance. Find the new instance by its Creation Time.

Instance creation takes about 1 to 5 minutes. Refresh the page to check the status.

How do I find the total number of RDS instances in my account?

Go to the Overview page in the ApsaraDB RDS console. This page shows the total number of RDS instances across all database engines, along with the regions and running instance counts.

I just created an instance but cannot find it. What should I check?
