AWS's fully managed platform for building autonomous AI agents inside Amazon Bedrock — with RAG via Knowledge Bases, tool calling via action groups (Lambda/OpenAPI/MCP), multi-agent collaboration, long-term memory, and sandboxed code interpretation.
AWS announced Agents for Amazon Bedrock as a preview in July 2023, and the service reached general availability in November 2023 (re:Invent) alongside Knowledge Bases. In 2024, AWS added short-term session memory, and in December 2024 — multi-agent collaboration (a supervisor agent coordinating specialized sub-agents). In 2025, AWS extended the offering with Amazon Bedrock AgentCore — a complementary runtime for deploying agents built in any open-source framework (LangGraph, CrewAI, Strands Agents) with isolated execution sandboxes. Bedrock Agents (managed builder) and AgentCore (deploy/operate) are positioned as two layers of the same AWS agent offering.
An agent is defined by a foundation model (Claude, Llama, Mistral, Nova, DeepSeek available in Bedrock), instruction prompts, and action groups — sets of APIs/functions delivered as Lambda + OpenAPI schema or return-of-control. RAG is handled by Bedrock Knowledge Bases — managed RAG with Titan/Cohere embeddings and support for vector stores: OpenSearch Serverless, Aurora PostgreSQL (pgvector), Pinecone, Redis Enterprise, MongoDB Atlas. A multi-agent supervisor orchestrates sub-agents via LLM-based reasoning or deterministic routing rules.
Bedrock Agents runs inside the customer's VPC with VPC Endpoints (AWS PrivateLink), supports KMS encryption (CMK), IAM authentication, Guardrails (content filtering, PII redaction, prompt injection protection), and Bedrock Model Invocation Logs to CloudWatch / S3. Code Interpretation runs in an isolated Firecracker sandbox. Available in AWS regions including us-east-1, us-west-2, eu-central-1, ap-northeast-1, and AWS GovCloud.
