Overview

Service Overview

Search Engine provides automated creation and configuration of the distributed search and analytics engines Elasticsearch and OpenSearch through a web-based console. Users can select a server type that fits the system configuration to set up a cluster, and it supports the data analysis and visualization tools Kibana and the OpenSearch dashboard.

Notice
  • Search Engine provides Elasticsearch Enterprise version and OpenSearch version.
  • Elasticsearch Enterprise’s software license uses a Bring Your Own License (BYOL), and the software license policy in cloud environments must follow the supplier’s policy.

Search Engine Cluster consists of multiple master nodes and data nodes. Data nodes can be installed from a minimum of 1 up to a maximum of 10, and are usually installed with 3 or more. If a master node is not installed separately, the data node also performs the role of the master node and can be installed up to a maximum of 10. When a master node is installed separately, data nodes can be up to 50.

Provided Features

Search Engine provides the following functions.

  • Auto Provisioning (Auto Provisioning): You can configure and set up Elasticsearch and OpenSearch clusters via UI.
  • Operation Control Management: Provides functionality to control the status of running servers. Restart is possible for reflecting configuration values, along with starting and stopping the cluster.
  • Backup and Recovery: Backup is possible using the built-in backup feature, and recovery can be performed to the point in time of the backup file.
  • Add Data Node: If cluster expansion is required, you can add nodes with the same specifications as the data nodes in use. Up to 10 nodes can be added within the cluster.
  • Visualization tool support: Provides data analysis and visualization tools, and supports Elasticsearch Kibana or OpenSearch dashboards.
  • Monitoring: CPU, memory, cluster performance monitoring information can be checked through the Cloud Monitoring service.

Components

Search Engine provides pre-validated engine versions and various server types according to the open source support policy. Users can select and use them according to the scale of the service they want to configure.

Engine Version

Search Engine supported engine versions are as follows.

Technical support can be used until the supplier’s EoTS (End of Technical Service) date, and the EOS date when new creation is stopped is set to six months before the EoTS date.

Since the EOS and EoTS dates may change according to the supplier’s policy, please refer to the supplier’s license management policy page for details.

Information

Search Engine’s next version is scheduled to be provided after March 2026. The actual service provision schedule may change.
