This section describes the relationship between CSS and other services.
CSS clusters are created in the subnets of a VPC. VPCs provide a secure, isolated, and logical network environment for your clusters.
In a CSS cluster, each node represents an ECS. When you create a cluster, ECSs are automatically created to serve as nodes.
CSS uses EVS to store index data. When you create a cluster, EVSs are automatically for cluster data storage.
Snapshots of CSS clusters are stored in OBS buckets.
IAM authenticates access to CSS.
CSS uses Cloud Eye to monitor cluster metrics in real time to ensure normal service running. The supported CSS metrics include the disk usage and cluster health status. You can learn about the disk usage of the cluster in a timely manner based on the disk usage metric. You can learn about the health status of a cluster based on the cluster health status metric.
With CTS, you can record operations associated with CSS for later query, audit, and backtrack operations.
If disk encryption is enabled for CSS clusters, you need to obtain the key provided by KMS to encrypt and decrypt the disk data.
