Elasticsearch subscription instances

The following figure shows the information of an Alibaba Cloud Elasticsearch instance that uses the subscription billing method. For parameter descriptions, see the following sections and Buy page.

  • Name: By default, the name of an Alibaba Cloud Elasticsearch instance is the same as its ID. You can edit the name of the instance. You can also search instances by name.
  • Internal Network Address: You can use the IP address of a VPC-connected ECS instance to access an Alibaba Cloud Elasticsearch instance.
    Notice If you access an Alibaba Cloud Elasticsearch instance through the Internet, data security is not guaranteed. To protect your data, we recommend that you purchase an ECS instance that is connected to the same VPC network as your Elasticsearch instance. You can then use an internal network address to access the Elasticsearch instance.
  • Internal Network Port: The following ports are supported:
    • Port 9200 for HTTP and HTTPS.
    • Port 9300 for TCP. Only Alibaba Cloud Elasticsearch 5.5.3 with Commercial Feature supports this port.
      Note You cannot use the transport client to access Alibaba Cloud Elasticsearch 6.3.2 with Commercial Feature and Alibaba Cloud Elasticsearch 6.7.0 with Commercial Feature through port 9300.
  • Public Network Access: You can use public network addresses to access Alibaba Cloud Elasticsearch instances.
  • Public Network Port: The following ports are supported:
    • Port 9200 for HTTP and HTTPS.
    • Port 9300 for TCP. Only Alibaba Cloud Elasticsearch 5.5.3 with Commercial Feature supports this port.
      Note
      • You cannot use the transport client to access Alibaba Cloud Elasticsearch 6.3.2 with Commercial Feature and Alibaba Cloud Elasticsearch 6.7.0 with Commercial Feature through port 9300.
      • To access an Elasticsearch instance through the Internet, you must configure the Public IP address whitelist. By default, the public network access feature forbids all IP addresses.
  • Protocol: By default, HTTP is selected. You can click Edit to change the protocol. Currently, you can choose HTTP or HTTPS. For more information, see Security settings.
  • Renew: You can click Renew on the right side of Basic Information to renew the instance. You can renew your subscription one or more months. The minimum renewal period is one month.

Elasticsearch pay-as-you-go instances

Remove data nodes

Currently, you can downgrade data nodes for Elasticsearch pay-as-you-go instances and Elasticsearch instances deployed in one zone. Elasticsearch subscription instances and instances deployed across zones are not supported. This function only allows you to remove data nodes from an Alibaba Cloud Elasticsearch instance. You cannot downgrade the specification or disk space of dedicated master nodes, client nodes, and Kibaba nodes. For more information, see Downgrade data nodes.

Upgrade

You can upgrade the instance specification, number of nodes, dedicated master node specification, and storage space per data node for an Elasticsearch instance. For more information, see Cluster upgrade.
