This topic describes how to create an ApsaraDB RDS for MariaDB instance in the ApsaraDB for RDS console. You can also call an API operation to create an ApsaraDB RDS for MariaDB instance.

For more information about billing, see Pricing, billing items, and billing methods.

A new ApsaraDB for RDS console is available for instance creation. You can choose the new console or switch back to the original console. For more information, see the following sections:

Prerequisites

You have an Alibaba Cloud account. For more information, see Sign up with Alibaba Cloud.

Precautions

Create an RDS instance in the new ApsaraDB for RDS console

  1. Log on to the new ApsaraDB for RDS console.
    Note You can click Back to Old Version in the upper-right corner to switch back to the original ApsaraDB for RDS console.
  2. Configure the following parameters.
    Parameter Description
    Billing Method
    • Subscription: A subscription instance is an instance that you subscribe to for a period of time and pay for up front. We recommend that you choose subscription billing for long-term use because it is more cost-effective than pay-as-you-go billing. You can receive larger discounts for longer subscription periods.
    • Pay-As-You-Go: A pay-as-you-go instance is charged per hour based on your actual resource usage. We recommend that you choose pay-as-you-go billing for short-term use. You can release your pay-as-you-go instance to reduce costs when you no longer need it.
    Region The region where the RDS instance resides.
    • You cannot change the region after you confirm your order.
    • To maximize access speed, we recommend that you select a region in close proximity to the geographic location where your users reside.
    • Make sure that the RDS instance is created in the same region as the ECS instance to which you want to connect. If the RDS and ECS instances reside in different regions, they cannot communicate over an internal network and therefore cannot deliver optimal performance.
    Database Engine The database engine and version that the RDS instance runs. Select the MariaDB database engine. Only MariaDB 10.3 is supported.
    Note The database engines and versions available vary based on the region you select.
    Edition The edition of the RDS instance. Only the High-availability option is available. In this edition, your database system consists of one primary instance and one secondary instance. The primary and secondary instances work in the classic high-availability architecture.
    Note The RDS editions available vary based on the region and database engine version you select. For more information, see ApsaraDB for RDS edition overview.
    Storage Type
    • Local SSD: A local SSD is housed on the same server as the database engine. Local SSDs reduce I/O latency.
    • Enhanced SSD: An enhanced SSD is an ultra-high performance disk provided by Alibaba Cloud based on the new generation of distributed block storage architecture. It integrates 25 Gigabit Ethernet and remote direct memory access (RDMA) technologies to reduce latency and deliver up to 1 million random input/output operations per second (IOPS).
    • Standard SSD: A standard SSD is an elastic block storage device that is designed based on the distributed storage architecture. Standard SSDs separate computing from storage.

    For more information, see Storage types.

    Zone of Primary Node

    The zone where the RDS instance resides. Each zone is an independent physical location within a region. There are no substantive differences between zones in the same region. If your database system spans multiple zones, it provides zone-level disaster recovery.

    You only need to specify Zone of Primary Node. The system will automatically specify Zone of Secondary Node.

    Instance Type
    • Entry-level: belongs to the general-purpose instance family. A general-purpose instance exclusively occupies the memory and I/O resources allocated to it, but shares CPU and storage resources with the other general-purpose instances that are deployed on the same server.
    • Enterprise-level: belongs to the dedicated or dedicated host instance family. A dedicated instance exclusively occupies the CPU, memory, storage, and I/O resources allocated to it. The top configuration of the dedicated instance family is the dedicated host. A dedicated host instance occupies all the CPU, memory, storage, and I/O resources on the server where it is housed.
    Note Each instance type supports a specific number of CPU cores, memory capacity, maximum number of connections, and maximum IOPS. For more information, see Primary instance types.
    Capacity The storage capacity that the RDS instance has available to store data files, system files, binary log files, and transaction files. You can adjust the storage capacity in increments of 5 GB.
    Note The dedicated instance family supports exclusive allocations of resources. The storage capacity of each instance type with local SSDs in this family is fixed. For more information, see Primary instance types.
  3. Click Next: System Configurations.
  4. Configure the following parameters.
    Parameter Description
    Network Type The network type of the RDS instance. Only the VPC option is available. A Virtual Private Cloud (VPC) is an isolated virtual network with higher security and better performance than a classic network. If you select the VPC network type, you must also specify VPC and VSwitch of Primary Node.
    Note Make sure that the primary RDS instance has the same network type as the ECS instance to which you want to connect. If both their network types are VPC, you must also make sure that they reside in the same VPC. Otherwise, they cannot communicate over an internal network.
    Resource Group The resource group to which the RDS instance belongs.
  5. Click Next: Confirm Order. In the Confirm Order step, confirm the settings in the Parameters section, specify Purchase Plan and Duration, read and select Terms of Service, and click Pay Now. You need to specify Duration only when you create a subscription instance.
