AWS Opensearch

Managed search and analytics service that lets you run OpenSearch clusters without managing infrastructure. Combines full-text search, vector search, log analytics, and observability in a single platform, with options for fully managed clusters or serverless scaling.

OpenSearch is Apache 2.0-licensed, part of the Linux Foundation, and powers workloads at scale with up to 25 PB of data. Zero-ETL integrations with popular data stores and native connections to AI model providers simplify building search and RAG applications without custom pipelines.

Key capabilities:

• Full-text, vector, and hybrid search with millisecond response times
• Log analytics and observability with anomaly detection
• Vector database for semantic search and RAG with foundation models
• Zero-ETL integration with DynamoDB, DocumentDB, S3, and CloudWatch
• Fully managed or serverless deployment options

Developers use it for application search, product catalogs, and data lake search. Log and trace analysis, security event correlation, and performance monitoring fit the observability stack. Vector search and RAG support semantic search, chatbots, and personalized recommendations. Integration with common AWS data sources and SDKs streamlines ingestion without ETL jobs.
