Elasticsearch:Create an Alibaba Cloud Elasticsearch cluster

Parameter

Description

Product Type

• Subscription: Recommended for long-term use of ES clusters. You make a one-time payment, and the price is lower than that of Pay-as-you-go.

• Pay-as-you-go: Suitable for short-term scenarios such as application development or feature testing. You are billed by the hour and can release the cluster at any time to stop billing. You can create a pay-as-you-go cluster first and switch it to Subscription after you confirm that the cluster meets your requirements.

Regions and Zones

Select a region based on your business requirements. The region cannot be changed after the cluster is created:

• The closer the region is to your users, the lower the network latency and the faster the access speed.

• If the ES cluster must communicate with other Alibaba Cloud services over an internal network, deploy the cluster and those services in the same region.

Number of Zones

• 1-AZ: A standard deployment mode suitable for non-critical workloads.

• 2-AZ: A cross-zone disaster recovery deployment mode suitable for production workloads.

• 3-AZ (default): A high availability (HA) deployment mode suitable for production workloads with higher availability requirements. After you select two or three zones, the page displays the Zone 2 and Zone 3 configuration items. The default value is Random. Keep the default value to let the system assign zones automatically, or specify them manually. For more information, see Deploy and manage a multi-zone cluster.

Network Type

Only Virtual Private Cloud (VPC) is supported.

VPC

Select a VPC in the selected region:

• (Recommended) If the ES cluster must communicate with other Alibaba Cloud services over an internal network, deploy the cluster and those services in the same VPC.

• If no VPC meets your business requirements, create one first. For more information, see Create a VPC and a vSwitch.

Virtual Switch

Only vSwitches in the specified VPC and the same zone as the ES cluster are displayed. If no vSwitch meets your business requirements, create one first. For more information, see Create a VPC and a vSwitch.

Cluster Type

• Engine-enhanced edition: 100% compatible with open-source Elasticsearch and provides enterprise features such as X-Pack free of charge. It is optimized for search, logging, and AI scenarios, and you can enable its enhanced capabilities as needed. Cloud-native management improves change efficiency, and the intelligent O&M ES Agent is ready to use.

• Standard Edition: 100% compatible with open-source Elasticsearch and provides enterprise features such as X-Pack free of charge. It covers multiple ES versions from 5.x to 9.x. Cloud-native management improves change efficiency, and the intelligent O&M ES Agent is ready to use. For more information, see Features by version and Feature overview.

Elasticsearch Version

• Engine-enhanced edition: Supports 9.x (Agent Engine Edition), 9.4.0, 8.17.0, 8.15.1, 7.16.2, 7.10.0, and 6.7.0.

Deployment Mode

• New cloud-native management mode: The deployment mode currently provided on the purchase page. It supports a broad range of cluster types and versions, provides out-of-the-box AI capabilities, and improves cluster O&M efficiency in areas such as scaling, monitoring, and alerting.

OpenStore storage-compute disaggregation (high-performance search scenario)

A storage-compute disaggregation architecture. Storage is billed based on actual usage, and scaling nodes does not require migrating underlying data. The default value is Disabled.

SpecificationsNode configuration

Click each node section to configure nodes based on your business requirements.

• For guidance on selecting node specifications, see Evaluate specifications and storage capacity.

• For detailed descriptions of node configurations, see Configure nodes for an Alibaba Cloud Elasticsearch cluster.

• Click Reset to Default in the lower-right corner of the section to restore modified node configurations to the default configurations.

• Data nodes on the international site do not provide the node specification family option, and node sections do not include Elastic Node.

Resource Group

Resource groups allow you to manage ES clusters as groups. For more information, see Manage permissions with resource groups.

Cluster Name

If you leave this field blank, the system automatically generates a name. You can change the cluster name on the Basic Information page after the cluster is created.

Username

The default account is elastic and cannot be changed. This account has the super administrator (Superuser) role of the cluster. You can use it to access the ES cluster and log on to the Kibana console. If you change the password of the elastic account, the change takes effect immediately and interrupts all existing connections that use the account because authentication fails. If this password is hard-coded in a business application, services may become unavailable. For security and to follow the principle of least privilege, do not use the elastic account directly in production code or applications. Create roles and standard users with specific permission scopes in the Kibana console for business use. For more information, see Manage user permissions with X-Pack roles.

Password

The password for the elastic account. This field cannot be empty.

Subscription Duration

If the product type is Subscription, select a subscription duration. (Recommended) Enable Auto-renewal to prevent the cluster from stopping or being released when the resources expire.

• For monthly subscriptions, the Unified Auto Renewal Cycle is one month.

• For yearly subscriptions, the Unified Auto Renewal Cycle is one year.

• Available durations are one month, one year, two years, and three years.
