## Summary

AWS re:Invent 2025 introduced Lambda Managed Instances, allowing functions to run on dedicated EC2 instances in your account while AWS handles management, addressing cost concerns at scale. Lambda Durable Functions enable multi-step workflows with checkpoints and replay mechanisms, supporting execution timeouts up to 1 year for async invocations. Additional announcements include S3 Vectors reaching GA with improved performance, S3 Tables gaining intelligent-tiering and replication support, and CloudFront adding mutual TLS authentication.
