# Amazon Bedrock AgentCore

> Bedrock AgentCore is the AWS managed agent runtime — providing memory, tool execution, observability, and identity for autonomous AI agents built on any framework.

## Definition

Amazon Bedrock AgentCore is AWS's **managed agent runtime and infrastructure layer** for production AI agents. It separates agent _logic_ (your code, LangGraph, CrewAI, Strands, or custom frameworks) from agent _operations_: session-isolated execution, memory, tool gateways, browser automation, sandboxed code interpretation, identity, and observability. AgentCore reached general availability in 2025 and, as of June 2026, is the recommended path when a Bedrock prototype needs scaling, audit trails, and compliance-friendly isolation without building Lambda-plus-DynamoDB plumbing from scratch. You still choose underlying foundation models (Claude Sonnet 4.6, Nova, Llama) for reasoning — AgentCore is not a model.

## When to use it

- **Production deployment** of multi-step agents after local prototyping — need concurrency, session isolation, and managed scaling.
- **Framework portability** — keep LangGraph/CrewAI/Strands orchestration but offload memory, tools, and traces to AWS-managed primitives.
- **Compliance-sensitive agents** (HIPAA, SOC 2) requiring auditable tool calls, identity per agent action, and CloudWatch/OpenTelemetry traces.
- **Long-running sessions** with **AgentCore Memory** — short-term conversation state and long-term semantic recall without custom vector-plus-summary pipelines.
- **Tool-rich agents** exposing existing REST APIs, Lambda functions, and AWS services through **AgentCore Gateway** with auth and throttling.

## When not to use it

- **Single-turn Bedrock Converse calls** — invoke the model API directly; AgentCore adds latency and cost overhead.
- **Read-only RAG Q&A** — [Bedrock Knowledge Bases](/glossary/rag-pipeline/) alone is simpler.
- **Hard sub-second latency SLAs** — serverless agent runtime cold starts are measured in seconds; warm pools and design matter.

## Tips

- Scope **AgentCore Identity** IAM roles per tool — never attach broad `*` policies to the agent execution role.
- Use **AgentCore Gateway** to wrap legacy APIs with consistent auth, rate limits, and CloudTrail logging instead of embedding credentials in agent code.
- Enable **Observability** early — trace replays shorten debugging time for non-deterministic agent failures.
- Treat **Browser** and **Code Interpreter** tools as high-risk — restrict to trusted prompts and sandbox networks.
- Keep business logic in your framework; use AgentCore for cross-cutting runtime concerns only.

## Gotchas

### Serious

- **Over-privileged agent roles** — a compromised agent with wide IAM access becomes an automated lateral movement tool.
- **Skipping human approval on write tools** — agents that mutate production data need confirmation steps or policy gates.

### Regular

- **Building custom memory on DynamoDB when AgentCore Memory fits** — reinvents summarization, recall ranking, and retention policies.
- **Confusing AgentCore with Bedrock Agents (classic)** — naming overlap exists; AgentCore is the newer managed runtime layer for custom frameworks.
- **Ignoring cold start in UX** — first message in a session may lag; set user expectations or keep sessions warm where cost allows.
