Your serverless attendee’s guide to AWS re:Invent 2026

This article provides a comprehensive guide to serverless and application integration sessions at AWS re:Invent 2026, held November 30 to December 4 in Las Vegas.

• New Lambda execution models: durable functions for long-running workflows, Managed Instances for always-on compute, and MicroVMs for sandboxed untrusted code
• AI agents as serverless consumers with orchestration patterns, tool design, and multi-agent architectures on EventBridge
• Event-driven architecture sessions covering foundational patterns, anti-patterns, retry strategies, and enterprise-scale event buses
• Orchestration guidance for Step Functions vs. durable functions with decision frameworks and hybrid patterns
• Full-stack serverless web applications with API Gateway, web frameworks, and real-time features
• Developer experience improvements including AI-assisted development with Kiro, testing strategies, and self-healing applications
• Performance and operations at scale: Lambda tuning, cost optimization, and lessons from 1M RPS deployments
• Serverless data processing with distributed maps and streaming workloads
• Community sessions featuring production experiences from companies like Honeycomb

The guide organizes sessions by type (breakout, workshop, chalk talk, builders, code talk, lightning) and topic to help attendees navigate the extensive serverless content.
