# Search Engine Service concept

Available in Classic and VPC

It describes the configuration of the Search Engine Service before learning the full scenario of using the Search Engine Service. A cluster provided by the Search Engine Service consists of 1 or 2 Manager Nodes and 3 or more Data Nodes, and consists of at least 4 servers. A detailed description of the manager node and data node is as follows:

- Manager node: Manages clusters and is used as a data entry channel
  - Serves as a Coordinate Node and has Kibana or OpenSearch Dashboards installed
  - For VPC environments: Accessible from outside the NAVER Cloud Platform to the IP address of the Load Balancer
  - For classic environments: Accessible from outside the NAVER Cloud Platform through the public IP address of the manager node
- Data node: The server on which the data is stored
  - All data are stored with duplexing and can operate normally even if there is an error in 1 server
  - You can install as many additional nodes as you want
  - Communication is possible only through the manager node

Based on the concepts described above, a schematic diagram of the Elasticsearch clusters configured in each platform environment is as follows:
