AWS re:Invent 2025 - Secure Multi-tenant SaaS with AWS Lambda: A Tenant Isolation Deep Dive (CNS381)
In this session, learn about AWS Lambda's execution environment lifecycle, diving deep into how the service manages isolation at the function level, and understanding the security implications of environment reuse patterns. Learn about traditional patterns for compute isolation in multi-tenant environments, as well as explore Lambda's tenant isolation mode - a new powerful capability that enables tenant-level compute separation without operational overhead.
