PolarDB:Quick purchase

Prerequisites

Before you begin, ensure that you have:

• A registered and active Alibaba Cloud account

Create a cluster

1. Go to the PolarDB Quick Purchase page.

2. Configure the following parameters:

   Parameter	Description
   Billing Method	Select how you want to pay for the cluster. If the billing method no longer fits your needs after creation, you can change it at any time. Subscription — Pay upfront. Longer subscription terms give larger discounts. Best for steady, predictable workloads. Pay-as-you-go — Charged based on actual resource usage with no upfront commitment. Best for variable or unpredictable workloads. Serverless — PolarDB automatically scales resources up and down based on load. No upfront resource selection required. Best for highly variable or bursty workloads.
   Region	The region where the cluster is deployed. Deploy the cluster in the same region as the Elastic Compute Service (ECS) instance running your application. Cross-region connections fall back to the Internet, which degrades performance.
   Database Engine	The database engine. Only PostgreSQL 14 is available in Quick Purchase. To use other versions, switch to the Custom Purchase tab.
   Database Edition	The edition of the cluster. Applies only when Billing Method is Subscription or Pay-as-you-go. Enterprise Edition Standard Edition For a detailed comparison, see Differences between Enterprise Edition and Standard Edition.
   Network Type	The virtual private cloud (VPC) and vSwitch for the cluster. If you have an existing VPC used by your ECS instances, select that VPC and its vSwitch. Otherwise, use the default VPC and vSwitch.
   Deployment Mode (Optional)	The node configuration and high-availability (HA) mode. Applies only when Billing Method is Subscription or Pay-as-you-go. For details, see High-availability mode. Single-node Deployment — One primary node. HA: Single Zone (Hot Standby Storage Cluster Disabled). Dual-node Deployment — One primary node and one read-only node, both in the same zone. HA: Single Zone (Hot Standby Storage Cluster Disabled). Cross-zone HA — One primary node and one read-only node distributed across two zones. Each zone holds a full copy of your data. HA: Double Zones (Hot Standby Storage Cluster Enabled).
   Node Specification	The compute specification for the cluster nodes. Select the specifications that best suit your business requirements. To access additional specifications, switch to the Custom Purchase tab.
   Storage Capacity (Optional)	The allocated storage size. Applies only when Billing Method is Subscription or Pay-as-you-go and Database Edition is Standard Edition.
   Storage Cost	Storage is billed hourly based on actual usage — no configuration required. Applies when Billing Method is Subscription or Pay-as-you-go and Database Edition is Enterprise Edition. For pricing details, see Storage billing.

3. Optionally, expand More Configurations and configure the following:

   Parameter	Description
   Resource Group	Assign the cluster to a resource group for centralized management of your Alibaba Cloud resources. A resource can belong to only one resource group. To create a new group, see Create a resource group.

4. In the order summary on the right, confirm the Billing Method, Region, Deployment Mode, and Resource Group. Then configure:

   Parameter	Description
   Quantity	The number of clusters to create in this order. Maximum: 50 clusters per order and 50 clusters per Alibaba Cloud account.
   Duration	Applies only when Billing Method is Subscription. Select the subscription term and enable Auto-renewal to prevent service interruptions caused by overdue payments.

5. Review the total cost and billing breakdown, read the terms of service, and click Buy Now.

6. On the Payment page, confirm your order and payment method, then click Subscribe.

Result

The cluster is created within 10 to 15 minutes after payment.

To view the cluster, go to the Clusters page and make sure you have selected the correct region.

What's next

After the cluster reaches the Running state, connect your application to it:
