Bedrock Stateful Runtime for Agents

🔑 Enhanced Key Takeaways

• •AgentCore Runtime supports extended execution up to 8 hours for long-running workloads involving multi-agent collaboration[1][2].
• •Features consumption-based pricing that bills only for active CPU processing, excluding I/O wait times during LLM responses[1].
• •Provides built-in observability via CloudWatch Generative AI service, tracing agent reasoning, tool calls, and model interactions[1][2][5].
• •Supports 100MB payloads for multimodal content (text, images, audio, video) and bidirectional streaming over HTTP/WebSocket[1].
• •Requires ARM64 Docker containers exposing port 8080 with /ping and /invocations endpoints for deployment[4].

🛠️ Technical Deep Dive

• •Supports HTTP REST API and MCP (Model Context Protocol) for agent-tool communication, with JSON-RPC for A2A (Agent-to-Agent) interactions[2][4].
• •Built-in authentication via IAM SigV4 for AWS or OAuth 2.0/JWT with providers like Cognito, Okta; assigns unique agent identities[2].
• •Session isolation maintains stateful context across invocations while preventing cross-user data leakage; states include Active (processing) and Idle[6].
• •Deployment uses versioned endpoints with unique ARNs; containers must support stateless streamable-HTTP and Agent Cards at /.well-known/agent-card.json[1][4].
• •VPC integration recommends same-AZ subnets and endpoints for low-latency access to private resources[8].
