Multi‑Agent System Across Clouds: Async, Stateless, and Secure
Use Celery with Redis for async cross‑cloud task delegation.
Configure Celery broker and external state store.
Summary
The article explains that cross‑cloud MAS requires asynchronous communication, stateless containers, and secure tool execution. It recommends replacing synchronous HTTP with Celery and Redis for task delegation, externalizing conversational state to Redis, and using the Model Context Protocol (MCP) to separate tool execution from the LLM. OpenTelemetry can trace distributed workflows.
Key architectural points include: asynchronous HTTP throttling, external state persistence, secure tool execution via MCP, and handling NAT firewalls with Pilot Protocol.
The guide provides code snippets for Celery tasks, Redis state storage, and MCP client usage.
Teams should adopt these patterns to avoid timeouts, preserve context across restarts, and secure tool access.
Key changes
- Replace synchronous HTTP with Celery + Redis
- Persist conversational state in Redis
- Use MCP to secure tool execution
- Externalize state to avoid container restarts
- Implement OpenTelemetry for tracing
- Handle NAT firewalls with Pilot Protocol
