ApsaraDB for HBase:Purchase a cluster

Procedure

1. Log on to the ApsaraDB for HBase console.
2. In the top navigation bar, select the region where the cluster that you want to manage is deployed.

3. On the Clusters page, click Create HBase Cluster.

4. On the buy page, configure the parameters. The following table describes the parameters.

   Configuration section	Parameter	Description
   Billing method	Product Type	Select HBase Cluster Subscription or HBase Cluster PAYG. HBase Cluster Subscription: You make an upfront payment for the resources when you purchase the cluster. The price is calculated based on your subscription. Note The subscription plan does not cover the fee for the backup service. After the backup service is enabled, you are charged for the backup service based on the pay-as-you-go billing method. HBase Cluster PAYG: You are charged based on the actual usage of the purchased service.
   Basic information	Service	Select HBase.
   	Region	The region where you want to deploy the cluster. Important The region cannot be changed after the cluster is created. To accelerate access from users to the cluster, we recommend that you select a region that is close to the geographical location of the users. Make sure that the ApsaraDB for HBase cluster is deployed in the same region as the Elastic Compute Service (ECS) instance to which you want the ApsaraDB for HBase cluster to connect. If the ApsaraDB for HBase cluster and the ECS instance are deployed in different regions, they cannot communicate over an internal network. In this case, they must communicate over the Internet, and the ApsaraDB for HBase cluster cannot deliver optimal performance.
   	Zone	Select a zone that resides in the specified region. Zones are isolated physical locations in a region. Each zone has its own independent power supply and network. Zones within the same region are connected over private connections. When a zone fails, the other zones are not affected.
   	Version	By default, version 2.0 is selected.
   	Cluster Name	The name of the cluster. You can specify a custom name.
   Network parameters	Network Type	The following two network types are available: VPC: VPCs are private networks deployed on Alibaba Cloud. VPCs are logically isolated from each other. You can customize the topology and IP addresses in a VPC. VPCs are suitable for users who have high network security requirements and network management capabilities. Classic Network: Services that use the classic network are deployed in the public infrastructure of Alibaba Cloud. These services are planned and managed by Alibaba Cloud. The classic network is suitable for users who require networks that are easy to use. Note Some regions do not support the classic network. You can check whether you can deploy the cluster in the classic network in a specified region in the console.
   	vpcId	Select a VPC from the drop-down list. For information about how to create a VPC, see Create a VPC and a vSwitch.
   	vswitchID	Select a vSwitch in the specified VPC. For information about how to create a vSwitch for a VPC, see Create a vSwitch.
   Specifications and storage	Master Node Specification	For information about how to select a specification for master nodes, see Cluster specifications.
   	MasterHA	High Availability is selected by default.
   	Core Node Disk Type	For information about how to select a storage medium, see Storage types.
   	Core Node Specification	For information about how to select a specification for core nodes, see Cluster specifications.
   	Core Nodes	By default, an ApsaraDB for HBase cluster contains two core nodes. You can add more core nodes after the cluster is created.
   	Single Core Node Capacity	The storage capacity of a single core node. The value ranges from 400 GB to 64,000 GB. Select a capacity based on your business requirements.
   	Whether to Use Cold Storage	ApsaraDB for HBase Standard Edition does not support the cold storage feature.
   Others	Resource Group	Resource groups allow you to group various cloud resources that belong to an Alibaba Cloud account and are deployed in different regions. This way, you can manage your resources in a centralized manner. You can select an existing resource group or create a resource group.
   	Duration	The subscription period of the cluster. This parameter is required if you specify to create a subscription cluster. Valid monthly subscription periods range from one month to nine months. Valid yearly subscription periods range from one year to three years. Note If you want to enable auto-renewal for the cluster, select Auto-renewal, and make sure that you have sufficient balance within your account before the system automatically renews the cluster.
