Relationship between service resources
With Yandex Managed Service for Elasticsearch, you can deploy and maintain Elasticsearch server clusters in the Yandex.Cloud infrastructure.
Elasticsearch is a specialized distributed document storage system. When a document is added to Elasticsearch, it gets added to the index. Data from the indexed document becomes available for search and analysis.
When creating a cluster, specify the following:
Host class: A VM template for deploying the cluster hosts. For a list of available host classes and their characteristics, see Host classes.
Environment where the cluster will be deployed:
PRODUCTION: For stable versions of your apps.
PRESTABLE: For testing, including the Managed Service for Elasticsearch service itself. The Prestable environment is first updated with new features, improvements, and bug fixes. However, not every update ensures backward compatibility.
This is a special user that is needed to manage clusters and cannot be deleted. It's assigned the
superuserrole and can perform any operations on clusters.
To perform routine tasks, we recommend creating individual users. For more information, see Managing Elasticsearch users.
Version of Elasticsearch.
Edition of Elasticsearch. For a list of available editions and supported features, see Elasticsearch editions.
An Elasticsearch cluster created in a folder can be accessed by all VMs connected to the same cloud network as the cluster.
A single-host cluster doesn't guarantee fault tolerance. A cluster with multiple hosts automatically provides fault tolerance for the Master node role. To ensure data safety in such a cluster, you need to configure index sharding and replication.
Cluster hosts may reside in different availability zones. Learn more about the geo scope of Yandex.Cloud in Availability zones.
The service can automatically access the system and diagnostic information of your databases to plot monitoring graphs and maintain the health of your cluster. The service never queries or uses the data that you saved to the database.
