ApsaraDB for HBase:Purchase a cluster

Procedure

1. Log on to the ApsaraDB for HBase console. On the Clusters page, click Create HBase Cluster.

2. On the buy page, configure the following parameters.

   Parameter	Description
   Billing method	Select subscription or pay-as-you-go. With the subscription billing method, you pay a one-time fee for the selected resources for a specific period. The pay-as-you-go billing method lets you use resources on demand and pay for your actual usage. You can release the resources at any time to stop incurring fees.
   Service	The value is fixed to ApsaraDB for HBase Performance-enhanced Edition.
   Deployment mode	Select single-zone or multi-zone.
   Version	The value is fixed to 2.0.
   Cluster name	Specify a custom name for the cluster.
   Region	The region where the cluster will be deployed. Important You cannot change the region after the cluster is created. We recommend that you select a region that is geographically close to your users to reduce network latency. To ensure optimal performance, make sure that the ApsaraDB for HBase cluster is in the same region as the ECS instances that connect to the cluster. This allows for internal network communication.
   Zone	A zone is a physical location within a region that has independent power and network infrastructure. Zones in the same VPC are interconnected over a private network, but failures are isolated between zones.
   Multi-zone combination	The available multi-zone combinations are displayed. Note This parameter is required only if the Deployment mode is set to multi-zone.
   Network type	Only VPC is supported.
   VPC	Select the desired VPC. To create a VPC, see Create a VPC and a vSwitch.
   vSwitch	Select the vSwitch that corresponds to the VPC. To create a vSwitch, see Create a vSwitch. Note This parameter is required only if the Deployment mode is set to single-zone.
   Primary zone, Primary zone vSwitch Standby zone, Standby zone vSwitch Arbiter zone, Arbiter zone vSwitch	If you select the multi-zone deployment mode, you must specify a zone and a vSwitch for each role. Note This parameter is required only if the Deployment mode is set to multi-zone.
   Master specification	Master nodes are configured for high availability by default. For guidance on selecting a specification, see Select cluster specifications.
   High availability	High availability is enabled by default.
   Core disk type	The following disk types are available. Select a disk type based on your business requirements. Enhanced SSD (ESSD): suitable for latency-sensitive online services. ESSDs provide low latency, as low as 1 ms to 2 ms. Standard SSD: Applications that require frequent data access or have high I/O workloads. NoSQL databases, such as MongoDB, HBase, and Cassandra. Ultra Disk: I/O-intensive applications. Small- and medium-sized relational databases. Local HDD: Development and test services. System disks. Local SSD: Applications that do not require frequent data access or have low I/O workloads. Cost-sensitive applications that require random read and write I/O. Note The supported core disk types vary by region. For more information, see the buy page.
   Encryption type	Select Disable Disk Encryption or Enable Disk Encryption.
   Core specification	For guidance on selecting a specification, see Select cluster specifications.
   Number of core nodes	The default is 2. You can add more nodes after the cluster is created.
   Storage capacity per core node	The default capacity and available range for a single core node depend on the core disk type. For more information, see the buy page.
   Log disk type	Standard SSDs and Ultra Disks are supported.
   Log specification	Select a log specification. Note This parameter is required only if the Deployment mode is set to multi-zone.
   Number of log nodes	Select the number of log nodes. Note This parameter is required only if the Deployment mode is set to multi-zone.
   Storage capacity per log node	Specify the storage capacity of a single log node. Valid values: 400 GB to 64,000 GB. Note This parameter is required only if the Deployment mode is set to multi-zone.
   Enable cold storage	ApsaraDB for HBase allows you to store data on a separate cold storage medium. This feature is suitable for cold data scenarios such as data archiving and historical data that is infrequently accessed. Yes: enables the cold storage feature. No: disables the cold storage feature. Note Cold storage is not supported for multi-zone deployments.
   Cold storage capacity	Select the cold storage capacity of the cluster. Unit: GB. Note This parameter is required only if you set the Enable cold storage parameter to Yes.
   Resource group	You can use resource groups to centrally manage multiple cloud resources across regions within a single Alibaba Cloud account. You can add the cluster to an existing resource group or create a new one.
   Subscription duration	If you create a subscription cluster, select a subscription duration. You can select a duration from 1 to 9 months, or from 1 to 3 years. Note If you want to automatically renew the subscription for the cluster upon expiration, select Auto-renewal Recommended. Make sure that your account has a sufficient balance before the cluster expires.
