Infrastructure

Amazon Bedrock AgentCore: The Enterprise Agent Platform

Amazon Bedrock AgentCore is a fully managed agentic platform for building, deploying, and operating AI agents securely at scale — using any framework, model, or protocol. It provides purpose-built infrastructure for agent scaling, powerful tools for enhanced capabilities, and essential controls for trustworthy operations in production.

  • Framework-agnostic: works with Strands, LangChain, CrewAI, or custom code
  • Built-in identity management for secure agent-to-resource access
  • Browser tool for agents to interact with web interfaces autonomously
  • Policy engine using natural language to set agent boundaries

Protocol

Model Context Protocol (MCP): The USB-C for AI

Created by Anthropic and now governed by the Linux Foundation's Agentic AI Foundation, MCP is an open standard that defines how AI applications connect to external data sources and tools. It standardizes the communication layer between AI models and the world — databases, APIs, file systems, and services — through a client-server architecture over JSON-RPC 2.0.

  • Adopted by Anthropic, OpenAI, Google DeepMind, and Microsoft
  • Supports async operations, stateless connections, and server identity
  • Official MCP Registry for discovering available servers
  • Two transports: STDIO for local, HTTP for remote connections

Protocol

A2A Protocol: How Agents Talk to Each Other

Google's Agent2Agent (A2A) protocol, launched in April 2025, is an open standard enabling AI agents built on different frameworks to discover, delegate tasks, and coordinate work across organizational boundaries. With 150+ organizations including AWS, Salesforce, SAP, and Cisco now supporting it, A2A is becoming the backbone of enterprise multi-agent communication.

  • Black-box handoff: agents collaborate without exposing proprietary logic
  • Agent Cards for capability discovery and secure delegation
  • Framework-agnostic: connects LangChain, CrewAI, Strands, and custom agents
  • Designed for cross-organizational agent interoperability

Framework

Strands Agents: Build Production AI Agents in Lines of Code

Strands Agents is AWS's open-source SDK that takes a model-driven approach to building AI agents. Instead of complex workflow definitions, you give an agent three things — a model, a system prompt, and tools — and Strands handles the agentic loop: reasoning, tool calling, reflection, and task completion. It crossed 1M+ downloads within months of its May 2025 release.

  • Three core components: Model + Prompt + Tools = Agent
  • Continuous agentic loop with autonomous reasoning and reflection
  • Native MCP integration for tool discovery and usage
  • Supports multi-agent patterns: Agents-as-Tools, Swarm, Graph, Workflow

Architecture Pattern

Agent-as-a-Tool: The Lightest Multi-Agent Pattern

The Agent-as-a-Tool pattern converts a specialized agent into a callable tool for an orchestrator agent. It's the natural evolution when a single agent can't handle all complexity. Each sub-agent specializes in a domain, maintains its own tools and context, while the orchestrator delegates and aggregates results — enabling parallel execution and modular scalability.

  • Orchestrator delegates tasks to specialized agents transparently
  • Each agent maintains its own tools, memory, and domain context
  • Supported natively in OpenAI Agents SDK, Strands, and ADK
  • Enables parallel processing and modular system maintenance

Architecture Pattern

Types of Memory for AI Agents: A Production Guide

Production AI agents rely on fundamentally different memory types — each solving a distinct problem. Drawing from cognitive science, modern agent memory architectures implement working memory (context window), episodic memory (past experiences), semantic memory (factual knowledge), and procedural memory (learned skills) — with different storage, retention, and retrieval trade-offs.

  • Working Memory: fast, ephemeral context within the active session
  • Episodic Memory: structured recall of past interactions and outcomes
  • Semantic Memory: persistent factual knowledge in vector stores or graphs
  • Procedural Memory: learned workflows, preferences, and skill patterns
