You can create an ApsaraDB RDS instance in the ApsaraDB RDS console or by calling an operation. This topic describes how to create an ApsaraDB RDS for MariaDB instance in the ApsaraDB RDS console.
Prerequisites
If you use a Resource Access Management (RAM) user to create an RDS instance, the AliyunRDSFullAccess and AliyunBSSOrderAccess policies must be attached to the RAM user. For more information, see Use RAM for resource authorization.
Procedure
On the ApsaraDB RDS buy page, click New Version or Back to Old Version to go to the new version or old version of the ApsaraDB RDS buy page.
New version
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.
NoteYou can view the price in the lower-right corner of the page. The price is displayed only after you configure all required parameters.
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.
NoteAfter 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.
Configure the Database Engine and Storage Type parameters.
NoteYou 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.
Configure the Database Engine parameter.
Select MariaDB. Only MariaDB 10.3 is supported.
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.
NoteYou can select Cloud Disk Encryption to ensure data security. For more information, see Configure the cloud disk encryption feature.
Configure the Network Type parameter. The Network Type parameter is fixed as VPC.
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.
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.
NoteIf 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.
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.
Configure the Instance Type parameter.
Configure the Category parameter. You can select General-purpose or Dedicated.
