What Is Cloud Search Service?

CSS

CSS is a fully managed, distributed search service based on open source Elasticsearch and OpenSearch. You can use it for structured and unstructured data search, and enable vector-based composite search, statistics generation, and reporting. CSS is a fully hosted cloud service of the ELK Stack and is compatible with open-source Elasticsearch, Logstash, Kibana, and Cerebro.

• Elasticsearch and OpenSearch

  Elasticsearch and OpenSearch are open-source distributed search engines that can be deployed in standalone or cluster mode. As the heart of the ELK Stack, Elasticsearch clusters support multi-condition search, statistical analysis, and create visualized reports of structured and unstructured text. For details about Elasticsearch, see the Elasticsearch: The Definitive Guide. For details about the OpenSearch search engine, see OpenSearch Documentation.

  CSS can be automatically deployed, where you can quickly create Elasticsearch and OpenSearch clusters. It provides the search engine optimization practices with zero O&M. Additionally, it has a robust monitoring system to present you key metrics, including clusters and query performance so that you can focus on the business logic.

• Logstash

  Logstash is an open-source data processing pipeline that ingests data from a multitude of sources, transforms it, and then sends it to your desired destination.

  Huawei Cloud Logstash is a fully managed data ingestion and processing service that is completely compatible with open-source Logstash. You can quickly create Logstash clusters in CSS. Data is scattered across many different systems in different formats. Huawei Cloud Logstash helps you get insights by easily processing data from a variety of data sources and dumping it to Elasticsearch clusters or other systems.

Functions

• Open-source compatibility

  Freely use native Elasticsearch and OpenSearch APIs and other software in the ecosystem, such as Logstash, Beats, and Kibana.

• Support for a variety of data sources

  A few simple configurations allow you to smoothly connect to multiple data sources, such as FTP, OBS, HBase, and Kafka. No extra coding is required.

• One-click operation

  One-click cluster application, capacity expansion, and restart from small-scale testing to large-scale rollout

• Flexible dictionary management

  You can custom your dictionaries. Modified settings take effect immediately without system restart.

• User-defined snapshot policies

  Trigger backup snapshots manually or configure an automated schedule.

Access Mode

You can access the public cloud platform with HTTPS-based application programming interfaces (APIs) or from a web-based console.

• Using APIs

  If you need to integrate CSS into a third-party system for secondary development, you can use APIs to access CSS. For details, see the Cloud Search Service API Reference.

• Web-based console

  If no secondary development is involved, the CSS management console is a convenient way to access CSS. If you have registered with the public cloud, log in to the management console and search for Cloud Search Service in the service list. If you do not sign up for the public cloud, click Register. In the displayed window, specify your basic information and click Register.
