Implement Server-Sent Events (SSE) to stream AI agent responses token by token to browser clients using FastAPI StreamingResponse, EventSource API, and proper reconnection handling.
Compare SSE and WebSockets for streaming AI agent outputs, understand the tradeoffs between unidirectional and bidirectional communication, and learn which protocol fits each real-time AI use case.
Deploy AI agents as serverless functions on AWS Lambda and Google Cloud Functions with cold start optimization, timeout handling, stateless architecture, and cost-effective scaling strategies.
Implement service discovery for AI agent microservices using Kubernetes DNS, Consul, and Eureka. Learn health checking, load balancing, and failover strategies that keep agent systems resilient.
Implement service mesh patterns for AI agent architectures using Istio and Linkerd — including traffic splitting for canary deployments, automatic retries, circuit breaking, and observability.
Outages trigger repetitive contacts and long hold times. Learn how AI chat and voice agents share updates, triage exceptions, and protect the service team.
Implement service-to-service authentication for multi-agent architectures using mTLS and service tokens. Covers certificate setup, trust boundaries, token exchange, and FastAPI integration.
Learn how to build secure session management for AI agent conversations. Covers session token design, server-side storage, expiration, concurrent session handling, and forced invalidation with FastAPI.
Design shared memory architectures for multi-agent teams that enable collective knowledge building, with contribution tracking, conflict resolution, and access control.
