Concise summaries of official AWS update announcements for AWS Lambda.
Information as of November 3, 2026.
AWS Lambda now supports Seekable OCI (SOCI) lazy loading for Lambda Managed Instances, reducing container startup times by up to 70%. Create a SOCI index in Amazon ECR and publish a function version to enable it automatically.
Lambda durable functions now include a new Telemetry Exporter plugin that captures step-by-step execution history and sends it to chosen destinations for operational and business insights.
AWS IAM Identity Center's Identity Store now delivers real-time events to Amazon EventBridge for user and group changes, enabling automated security and compliance workflows
AWS Lambda MicroVMs is now available in Asia Pacific (Hong Kong), Asia Pacific (Malaysia), Asia Pacific (Thailand), and Europe (Spain), enabling developers to run isolated compute environments closer to end-users without managing virtualization infrastructure.
AWS Lambda durable functions are now available in AWS GovCloud (US-West) and AWS GovCloud (US-East) Regions, enabling government customers and regulated industries to build reliable multi-step applications and AI workflows.
AWS Lambda recursive loop detection now works with EventBridge Custom event buses, automatically stopping loops and protecting against runaway usage and unexpected charges. Enabled by default with no configuration required.
AWS Lambda Durable Functions now allows up to 30,000 durable operations per execution and 1 MB checkpoint payloads, enabling more complex workflows and longer polling periods.
AWS Lambda durable functions are now available in the AWS European Sovereign Cloud region, enabling checkpointing, automatic recovery, and execution pausing without compute charges for on-demand functions
AWS Lambda durable functions now integrates with Pydantic AI, enabling AI agents to resume from the last completed step after interruptions without requiring custom checkpoint or retry logic.
AWS Lambda recursive loop detection is now available in the Europe Sovereign Cloud. It is enabled by default and automatically detects and stops recursive invocations between Lambda functions and supported services, preventing unexpected billing.
AWS Lambda supports Graviton5-powered C9g, C9gd, M9g, and M9gd instances on Lambda Managed Instances, delivering up to 25% better compute performance compared to Graviton4-powered instances
AWS Lambda recursive loop detection is now available in all commercial regions by default, automatically detecting and stopping recursive invocations between Lambda functions and supported services
AWS Lambda MicroVMs now supports AWS PrivateLink, enabling private connectivity directly from VPC resources without exposing traffic to the public internet. This helps regulated workloads meet strict network isolation requirements.
AWS Lambda now offers Node.js 26 and Python 3.15 managed runtimes in public preview, allowing users to test and provide feedback before general availability
AWS Lambda supports full IAM resource-based policies, allowing multiple principals and actions in a single policy document
AWS Lambda MicroVMs offers VM-level isolation and near-instant startup for secure, stateful code execution. It enables dedicated environments for users or jobs without managing virtualization infrastructure.
AWS Lambda now supports scalable network bandwidth for functions outside a VPC, allowing bandwidth to scale from 625 Mbps at 2 GB memory up to 3,000 Mbps at 10 GB memory, reducing execution time and cost for latency-sensitive workloads.
AWS Lambda now offers Java 8, 11, and 17 runtimes on Amazon Linux 2023, enabling migration from AL2 without upgrading Java versions.
AWS Lambda Durable Execution SDK for .NET is now generally available, enabling C# developers to build long-running workflows directly in Lambda
AWS Lambda durable functions now allow encryption of execution data with customer managed keys via AWS KMS, enabling compliance in regulated industries.
AWS Lambda now supports referencing code directly from Amazon S3 buckets, eliminating storage limits and reducing function activation time. The default limit for Lambda-managed storage has also increased from 75GB to 300GB per Region per account
