Function Overview

Cloud Search Service (CSS) is a fully managed cloud service of the ELK Stack and is compatible with open-source Elasticsearch, Kibana, and Cerebro.

CSS supports Elasticsearch clusters. You can create a cluster in security or non-security mode. CSS Elasticsearch clusters can be used in diverse scenarios, including log analysis and site search.

You can access a cluster that has the security mode enabled through the public IP address provided by the system.

For CSS clusters that have security mode enabled, you can access Kibana through the Internet after configuring Kibana public access. For a cluster that has security mode enabled, CSS allows you to enable Kibana public access and configure access bandwidth. After the configuration is complete, the cluster obtains a Kibana public IP address that you can use to access Kibana of this cluster.

You can configure Kibana public access when creating a cluster or configure this function after enabling security mode for a cluster.

You can back up index data in clusters. If data loss occurs or you want to retrieve data of a specified duration, you can restore the index data. Index backup is implemented by creating cluster snapshots. When creating a backup for the first time, you are advised to back up data of all indices.

You can migrate data from one cluster to another. In certain scenarios, for example, if changing specifications of the cluster cannot meet your requirementsdue to the growing business data, you can create a cluster of higher specifications and migrate all data of the current cluster to the new one. Alternatively, you can merge indices in two clusters to one cluster to meet your business needs. CSS enables you to migrate cluster data by using the index backup and restoration function, specifically, by restoring the snapshot of a cluster to the target cluster.

CSS provides log backup and search functions to help you locate faults. You can back up cluster logs to OBS buckets and download required log files to analyze and locate faults.

CSS provides you with cold data nodes. You can store data that requires query response in seconds on high-performance nodes and store data that requires query response in minutes on cold data nodes with large capacity and low specifications.

The VPC endpoint service allows you to access the cluster through a private domain name. When the VPC endpoint service is enabled, the system creates a VPC endpoint for you by default. 

CSS integrates the capabilities of Huawei's vector search engine through the Elasticsearch plug-in, supporting high-performance, high-precision, low-cost, and multi-modal search. It also supports all the native Elasticsearch capabilities, including distributed deployment, multi-copy, disaster recovery, error recovery, snapshot, and permission control, compatible with the entire Elasticsearch ecosystem. Currently, the vector search plug-in is integrated only in CSS 7.6.2.
