Today AWS Announced Amazon Bedrock AgentCore Runtime for Secure and Scalable AI Agent Deployment
Amazon Web Services has unveiled Amazon Bedrock AgentCore Runtime, a purpose-built serverless hosting environment designed specifically for AI agents and tools, addressing key challenges that have prevented promising agent prototypes from reaching production environments, according to the company announcement.
Key Takeaways
- AgentCore Runtime supports different agent frameworks and models, allowing developers to use LangGraph, CrewAI, Strands, or custom agents without requiring architectural changes
- Deployment requires minimal code changes (just four lines) to get agents running in production with built-in scaling capabilities
- The service provides true session isolation with dedicated microVMs for each user session, eliminating cross-contamination risks
- AgentCore Runtime offers embedded identity management with IAM SigV4 and OAuth/JWT authentication options
- The platform supports payloads up to 100MB and allows for asynchronous multi-hour agent operations (up to 8 hours)
Framework and Model Flexibility
According to AWS, AgentCore Runtime's framework-agnostic approach allows teams to use their preferred agent architecture and model provider. Developers can integrate different LLMs from providers like Amazon Bedrock, Anthropic, OpenAI, or Google, while maintaining a unified deployment pattern. The service requires minimal code changes to existing agent implementations, regardless of the underlying framework.
The deployment process involves adding just four lines of code to existing agent applications: importing the BedrockAgentCoreApp module, initializing the app, decorating the entrypoint function, and running the app. AWS provides a starter toolkit that simplifies configuration and deployment.
Security and Identity Management
A key differentiator for AgentCore Runtime is its approach to security through session isolation. The service provisions dedicated microVMs that can persist for up to 8 hours, enabling stateful agent workflows while maintaining complete isolation between user sessions. Each session receives isolated compute, memory, and file system resources, preventing data leakage between users.
The embedded identity system offers two authentication mechanisms: IAM SigV4 Authentication for agents operating within AWS security boundaries, and OAuth-based JWT Bearer Token Authentication for integration with existing enterprise identity providers like Amazon Cognito, Okta, or Microsoft Entra ID.
"AgentCore Runtime provides consistent, deterministic isolation boundaries regardless of agent execution patterns, delivering the predictable security properties required for enterprise deployments," according to the announcement.
State Persistence and Memory Management
For maintaining agent state, AgentCore Runtime works with Amazon Bedrock AgentCore Memory to provide both ephemeral session-specific state and persistent storage. Short-term memory captures raw interactions using methods like create_event
, while long-term memory uses configurable strategies to extract key insights from these interactions.
This hybrid approach allows agents to maintain fast, contextual responses during active sessions while building cumulative intelligence over time, avoiding the traditional trade-off between conversation speed and long-term learning.
Large Payload and Asynchronous Processing
Unlike traditional systems that typically limit payloads to a few megabytes, AgentCore Runtime supports payloads up to 100MB. This enables agents to process substantial datasets, high-resolution images, audio, and comprehensive document collections in a single invocation without requiring complex file chunking or external storage solutions.
For complex tasks requiring significant processing time, the service supports asynchronous operations for up to 8 hours. Developers can implement asynchronous agents with minimal code changes using the add_async_task
and complete_async_task
methods, transforming synchronous agents into fully asynchronous, interactive systems.
Cost-Efficient Resource Management
AWS has implemented a consumption-based pricing model for AgentCore Runtime that charges only for actual resource usage. Unlike traditional compute models that bill for allocated resources regardless of utilization, users don't pay for CPU resources during I/O wait periods or when agents are waiting for LLM responses or external API calls.
According to AWS examples, this can represent up to a 70% reduction in CPU costs compared to traditional models for typical agent workloads that spend significant time waiting for external processes to complete.
Analyst's Note
Amazon Bedrock AgentCore Runtime represents a significant advancement in AI agent infrastructure by addressing fundamental deployment challenges that have historically blocked enterprise adoption. The combination of session isolation, identity management, and consumption-based pricing creates a compelling platform for organizations looking to move beyond proof-of-concept implementations.
The most notable innovation is the microVM isolation approach, which provides stronger security guarantees than container-based solutions typically used for agent deployment. This addresses a critical concern for enterprises deploying multi-tenant agent applications, as illustrated by the Asana case study mentioned in the announcement where cross-tenant data contamination occurred due to insufficient isolation.
For organizations exploring AI agent deployments, AWS has provided comprehensive resources including sample implementations demonstrating integrations with popular frameworks like LangGraph, CrewAI, and OpenAI Agents.
