Amazon OpenSearch Service

What is it​

A managed service that makes it easy to deploy, operate, and scale OpenSearch clusters (an open-source fork of Elasticsearch) in the AWS Cloud.

What it's for​

Used for real-time search, analysis, and visualization of data, such as application logs, monitoring data, and security analytics.

Use cases​

  • Log analysis and application monitoring
  • Full-text search and e-commerce search
  • Security analytics and anomaly detection
  • Clickstream data analysis

Key points​

  • Managed: AWS handles deployment, scaling, and maintenance
  • Scalable: Easily scalable to handle large volumes of data
  • OpenSearch: Based on OpenSearch, which is compatible with the Elasticsearch API
  • Real-time Search and Analytics: Ideal for use cases requiring immediate insights
  • Integration: Integrates with other AWS services like Amazon Kinesis Data Firehose and AWS Lambda

Comparison​

  • Amazon OpenSearch Service vs. Self-managed Elasticsearch: OpenSearch Service offers the convenience of a managed service, eliminating the need to manage the underlying infrastructure, while self-managed Elasticsearch requires the user to handle all operations and scalability.
