Quick purchase-PolarDB(PolarDB)-阿里云帮助中心

This topic describes how to quickly create a PolarDB cluster on the Quick Purchase page in the PolarDB console.

Prerequisites

You have signed up for an Alibaba Cloud account and are logged in. For more information, see Sign up for and log on to an Alibaba Cloud account.

Note

PolarDB provides the price calculator and resource plan calculator. You can use the calculators to obtain information about the product pricing, estimate costs, and select a product type that meets your business requirements.

Price calculator: allows you to estimate the overall cost based on the details and storage capacity of the cluster that you select.
Resource plan calculator: allows you to estimate required compute capacity and storage capacity based on your business requirements and usage duration. The calculator can also provide recommendations on the specifications of storage plans and compute plans for clusters with defined specifications.

Procedure

1. Basic configuration

Go to the Quick purchase page in the PolarDB console. You can quickly create a PolarDB for MySQL cluster by configuring just a few parameters. The following table describes these parameters. You can keep the default values for other settings. For detailed instructions on how to create a cluster, see Custom Purchase.

Parameter	Description
Billing Method
Region	Select the region where you want to create the cluster. Note For optimal performance, ensure your PolarDB cluster and the ECS instance that will connect to it are in the same region. Otherwise, they cannot communicate over the private network and must connect over the public internet, which degrades performance.
Database Engine	Select the database engine for the cluster. MySQL 8.0.1 MySQL 8.0.2 Note The Quick purchase page supports only clusters that run MySQL 8.0. To purchase a cluster that runs a different MySQL version, switch to the Custom purchase tab in the upper-left corner.
Service Edition	Select the edition of the cluster. Enterprise Edition Standard Edition Note Enterprise Edition and Standard Edition differ in features. For more information, see Feature comparison of Enterprise Edition and Standard Edition.
Network Type	Configure the VPC and vSwitch for the cluster. Note If you have an existing VPC that meets your network requirements, you can select that VPC and its vSwitch. For example, you can select the VPC and vSwitch of an existing ECS instance. If you do not have a suitable VPC, you can use the default VPC and vSwitch.
Deployment Mode (Optional)	Select the number of nodes and the high-availability mode for the cluster. For more information, see High-availability mode (hot standby cluster). Single-node: Includes only one primary node (read/write). Number of nodes: 1. High-availability mode: Single-AZ (Hot standby storage cluster disabled). Dual-node high availability: Includes one primary node (read/write) and one read-only node. Number of nodes: 2. High-availability mode: Single-AZ (Hot standby storage cluster disabled). Cross-AZ high availability: Includes one primary node (read/write) and one read-only node. Data is distributed across multiple availability zones, with a full data copy in both the primary and secondary availability zones. Number of nodes: 2. High-availability mode: Dual-AZ (Hot standby storage cluster enabled). Triple-zone strong consistency deployment: Disabled. Note This parameter is available only if the billing method is subscription or pay-as-you-go.
Node Specifications	Select the compute node specifications for the cluster. Select specifications based on your business requirements. To purchase other specifications, switch to the Custom purchase tab in the upper-left corner.
Storage capacity (Optional)	Configure the storage capacity for the cluster. Note This parameter is available only if the billing method is subscription or pay-as-you-go and the edition is Standard Edition.

2. Advanced options (optional)

Parameter	Description
Resource Group	Select a target resource group from your list of existing groupsCreate a resource group. Note A resource group is a container for centrally managing related resources under a single Alibaba Cloud account. A resource can belong to only one resource group.
Parameter Template	Select a custom or system-default parameter template. Note The drop-down list displays all custom and system-default parameter templates available in the current region.
Time zone	Set the time zone for the cluster. The default time zone is UTC+08:00.
Table name case sensitivity	Specify whether table names in the cluster are case-sensitive. You can select Not Case-sensitive (Default). If your on-premises database is case-sensitive, select Case-sensitive to facilitate data migration. Note This setting cannot be changed after the cluster is created, so choose this option carefully.

3. Quantity and order confirmation

Actions	Description
Review configurations	Confirm that all settings, such as Billing method, Region, Deployment mode, and Resource group, are correct.
Specify the Quantity of clusters to create.	If you selected the subscription billing method, you must also specify the Subscription Duration and select whether to enable auto-renewal. Note You can create up to 50 clusters at a time, which is useful for scenarios such as batch game server launches. Each Alibaba Cloud account is limited to a maximum of 50 clusters. If you select the subscription billing method, we recommend that you enable auto-renewal to prevent service interruptions caused by expiration.
Confirm terms of service	Read and agree to the Alibaba Cloud Terms of Service and User Agreement.
Verify fees	Review the total cost and the detailed cost breakdown for items such as compute specifications, storage, and network.
Make payment	On the Purchase page, confirm the order details, select a payment method, and then click Purchase.
Wait for cluster creation	After you complete the purchase, cluster creation takes 10 to 15 minutes. You can then view the new cluster in the cluster list. Note If the cluster status is Creating, the cluster is still being provisioned and is not available. The cluster is ready for use once its status changes to Running. Ensure that you have selected the correct region in the console. Otherwise, the cluster you created will not appear in the list.
