Features

AWS manages software installing, upgrading, patching, scaling (up to 3 PB), and cross-Region replicating with no downtime. OpenSearch Service is also bundled with a dashboard visualization tool, Amazon OpenSearch Dashboards, which helps visualize not only log and trace data, but also machine learning (ML)-powered results for anomaly detection and search relevance ranking.

Managed OpenSearch

Run search workloads simply without the hassle of configuring, managing, and scaling OpenSearch clusters. OpenSearch Service provides the power of open-source search with interactive millisecond response times. Additionally, Amazon OpenSearch Serverless enables search and log analytics without provisioning and adjusting resources, automatically scaling resources based on your application's needs.

Integration with other AWS services

Simply integrate with other AWS services to deliver expanded search and analytics functionality. This includes seamless integration with Amazon DynamoDB and Amazon DocumentDB databases for advanced search on stored data, as well as frictionless search across Amazon Simple Storage Service (Amazon S3) to reduce the need for separate data indexing. You can now directly query and visualize Amazon CloudWatch Logs data in near real-time using Amazon OpenSearch Service without complex data pipelines or having to export or transform the data first. This zero ETL integration centralizes log data collection and storage, leveraging the scalable ingestion and storage of CloudWatch Logs along with the advanced analytics capabilities of OpenSearch Service. Zero ETL integration between Amazon Security Lake and Amazon OpenSearch Service, allows you to efficiently search and analyze voluminous security data that were previously cost-prohibitive to analyze without data integration challenges, streamlining security investigations and providing comprehensive visibility of your security landscape. The service further integrates with AWS model hosting services like Amazon Bedrock and Amazon SageMaker, enabling vector embeddings generation and storage, and AWS CloudTrail and AWS CloudWatch for enhanced cluster management and security auditing.
