This topic describes how to configure the parameters on the buy page when you purchase an Alibaba Cloud Elasticsearch cluster.
Basic parameters
Parameter | Description |
---|---|
Billing Method |
Elasticsearch provides two billing methods: Subscription and Pay-As-You-Go.
|
Region | For more information, see Regions and zones. |
Zone | For more information, see Regions and zones. |
Number of Zones |
Note
|
Network Type | The value of this parameter can be only VPC. |
VPC | Select a virtual private cloud (VPC) in the current region.
Note If you want to use an Elastic Compute Service (ECS) instance to access your Elasticsearch
cluster over a VPC, make sure that the ECS instance and Elasticsearch cluster reside
in the same VPC.
|
VSwitch | After you specify a VPC, all the available vSwitches in the current zone are displayed.
Note If no vSwitch is displayed, you must check whether you select a correct zone or whether
vSwitches are created in the selected zone.
|
Resource Group | Select the resource group to which the cluster belongs. For more information, see Use RAM to create and authorize resource groups. |
Instance Type | The value of this parameter can be only X-Pack Version. |
Version | Valid values: 7.10, 7.7, 6.8, 6.7, 6.3, 5.6, and 5.5.
Note
|
Parameters for different types of nodes | For more information, see Data node, Kibana node, Warm node, Dedicated master node, and Client node. |
Username | The username of the account that is used to access the cluster and log on to the Kibana
console of the cluster. The default value of this parameter is elastic.
Important If you use the elastic account to access your Elasticsearch cluster and reset the
password of the account, it may require some time for the new password to take effect.
During this period, you cannot use the elastic account to access the cluster. Therefore,
we recommend that you do not use the elastic account to access an Elasticsearch cluster.
You can log on to the Kibana console of your Elasticsearch cluster and create a user
with the required role to access the cluster. For more information, see Use the RBAC mechanism provided by Elasticsearch X-Pack to implement access control
|
Password | The password of the elastic account. This parameter is required. |

Data node
Data nodes store index data. You can use data nodes to add, remove, search for, modify, or aggregate documents in indexes. Data nodes have high CPU, memory, and I/O requirements. When you optimize the performance of an Elasticsearch cluster, you must monitor the statuses of the data nodes in the cluster. If the resources of the cluster are insufficient, we recommend that you add data nodes to the cluster.
Parameter | Description |
---|---|
Data Node | The value of this parameter can be only Yes. |
Data Node Type | For more information about the specifications of data nodes and the prices for different
specifications, see Pricing.
Important
|
Data Nodes | The number of data nodes that you want to purchase. The default value of this parameter
is 3, and the valid values of this parameter are from 2 to 50.
Important
|
Data Node Disk Type | Standard SSD, ESSD, and Ultra Disk are supported.
|
Performance Level | The performance level of the ESSD. This parameter is displayed only if you set the Data Node Disk Type parameter to ESSD. |
Data Node Disk Encryption | Disk encryption offers the maximum data security without requiring you to make additional
changes to your businesses and applications. However, disk encryption may have a small
impact on the performance of your Elasticsearch services. Disk encryption is free
of charge. No additional fees are generated when you read data from or write data
to encrypted disks. For more information about how to implement disk encryption, see
Encryption overview.
After the cluster is created, you can check whether disk encryption is enabled for the cluster in the Node Visualization section of the Basic Information page in the console. For more information, see View the cluster status and node information. Note
|
Data Node Storage Space | The storage space of each data node depends on the disk type.
|
Kibana node
The value of the Kibana Node parameter can be only Yes. Alibaba Cloud offers you a free Kibana node with one vCPU and 2 GiB of memory. You can also purchase a Kibana node with higher specifications.
Warm node
- Frequently queried or written indexes
- Infrequently queried or written indexes, typically indexes of records
Parameter | Description |
---|---|
Warm Node |
The default value of this parameter is No. On the buy page or configuration upgrade page, click Yes on the right side of Warm Node to purchase warm nodes. You can also upgrade
purchased warm nodes on the configuration upgrade page. Your cluster is then charged
based on the new specifications. For more information about the prices for the specifications,
see Pricing.
Note You cannot release the warm nodes that you have purchased.
|
Warm Nodes | The number of warm nodes that you want to purchase. The default value and valid values
of this parameter vary based on the value of the Number of Zones parameter.
Note The number of warm nodes that you purchase must be a multiple of the number of zones.
|
Warm Node Type | The specifications of warm nodes on the buy page prevail. |
Warm Node Disk Type | The value of this parameter can be only Ultra Disk. |
Warm Node Disk Encryption | Disk encryption offers the maximum data security without requiring you to make additional
changes to your businesses and applications. However, disk encryption may have a small
impact on the performance of your Elasticsearch services. Disk encryption is free
of charge. No additional fees are generated when you read data from or write data
to encrypted disks.
After the cluster is created, you can check whether disk encryption is enabled for the cluster in the Node Visualization section of the Basic Information page in the console. For more information, see View the cluster status and node information. Note
|
Warm Node Storage Space | The storage space of each warm node. The minimum value of this parameter is 500. Unit: GiB. You can configure this parameter based on your business requirements. |
Node type | Startup parameter |
---|---|
Data node | -Enode.attr.box_type=hot |
Warm node | -Enode.attr.box_type=warm |
Dedicated master node
You can use dedicated master nodes to perform operations on clusters. You can create or delete indexes, track nodes, and allocate shards. The stability of dedicated master nodes is important to the health of clusters. By default, each node in a cluster may be used as a dedicated master node. Operations, such as data indexing, searches, and queries, require a large number of CPU, memory, and I/O resources. To ensure the stability of a cluster, we recommend that you purchase dedicated master nodes to separate the dedicated master nodes from data nodes.
Parameter | Description |
---|---|
Dedicated Master Node | For a single-zone Elasticsearch cluster, the default value of this parameter is No,
and you can change the value. For a multi-zone Elasticsearch cluster, the default
value of this parameter is Yes, and you cannot change the value.
When you purchase a single-zone cluster, you can set the Dedicated Master Node parameter to Yes and purchase dedicated master nodes. You can also purchase dedicated master nodes or upgrade purchased dedicated master nodes when you upgrade the configuration of your Elasticsearch cluster. Your cluster is then charged based on the new specifications. For more information about the prices for different specifications, see Pricing. Note
|
Dedicated Master Node Type | The default value of this parameter is 2C 8GB, which is the minimum specifications for a dedicated master node. You can configure this parameter based on your requirements. |
Dedicated Master Nodes | The value of this parameter can be only 3. |
Dedicated Master Node Disk Type | Standard SSD and ESSD are supported. The default value of this parameter is Standard SSD. For more information about disks, see Data node. |
Dedicated Master Node Storage Space | The value of this parameter can be only 20G. |
Client node
You can purchase client nodes to share the CPU overheads of data nodes. This improves the computing performance and service stability of your Elasticsearch cluster. For CPU-intensive services, we recommend that you purchase client nodes, such as for services that require a large number of aggregate queries. For more information about client nodes, see Elasticsearch Node.
Parameter | Description |
---|---|
Client Node | The default value of this parameter is No. You can configure this parameter based
on your business requirements.
You can set the Client Node parameter to Yes and purchase client nodes when you purchase an Elasticsearch cluster. You can also purchase client nodes or upgrade purchased client nodes when you upgrade the configuration of your Elasticsearch cluster. Your cluster is then charged based on the new specifications. For more information about the prices for different specifications, see Pricing. Note You cannot release the client nodes that you have purchased.
|
Client Node Type | The default value of this parameter is 2C 8GB. You can configure this parameter based on your business requirements. |
