Amazon OpenSearch Service

Amazon OpenSearch Service is a fully managed solution from AWS that simplifies the deployment, operation, and scaling of OpenSearch clusters for search, analytics, and generative AI workloads. As an open-source, Apache 2.0-licensed search and analytics suite, OpenSearch Service enables organizations to focus on innovation and operational efficiency without the burden of infrastructure management or deep cluster expertise.

The service offers flexible deployment options, allowing users to choose between fully managed clusters for granular control or OpenSearch Serverless for automatic resource optimization and seamless scaling. OpenSearch Service integrates natively with a wide range of AWS services, including Amazon DynamoDB, Amazon DocumentDB, Amazon S3, Amazon Bedrock, and Amazon SageMaker, as well as third-party AI models, enabling rapid development of AI-powered search and analytics applications.

• AI-Powered Search: Delivers advanced search experiences with support for traditional, vector-driven, and hybrid search, including natural language queries and precise keyword matching.
• Generative AI Integration: Features an integrated vector database for efficient management of billions of vectors, supporting generative AI use cases and Retrieval-Augmented Generation (RAG) applications.
• Operational Observability: Provides unified dashboards for analyzing logs, traces, and metrics, with direct query capabilities for Amazon S3, CloudWatch, and Security Lake, and built-in machine learning for anomaly detection and alerting.
• Comprehensive Security: Offers robust security features such as encryption, index-level and document-level access controls, network isolation, and compliance enablement across industry standards.
• Scalability and Performance: Supports workloads up to 25 PB, 1,000 data nodes, and 200 coordinator nodes, with millisecond response times for search and analytics operations.
• Data Ingestion and Transformation: Includes Amazon OpenSearch Ingestion for scalable, automated data ingestion, transformation, and routing, with features for deduplication, sampling, and data quality enforcement.
• Seamless AWS Integration: Easily connects with other AWS services for expanded search, analytics, and security capabilities, including zero-ETL integrations and direct querying of log and security data.

Amazon OpenSearch Service is ideal for use cases such as real-time log analytics, observability, personalized search, semantic and multimodal search, and powering generative AI applications. Its managed nature, advanced security, and deep AWS integration make it a compelling choice for organizations seeking scalable, reliable, and innovative search and analytics solutions.
