AWS Lambda's Self-Managed Code Storage Lifts the Account Quota, Not the Function Size Limit
Scored daily by a customisable AI persona to surface the most relevant engineering leadership news.
AWS Lambda self-managed code storage quota increase is immediately actionable for serverless deployments.
AWS Lambda's new self-managed code storage lets functions reference deployment packages directly in customer-owned S3 buckets, removing the per-Region account-level storage quota and raising the default Lambda-managed storage from 75 GB to 300 GB. The change does not alter per-function package limits, which remain 50 MB zipped and 250 MB unzipped for zip-based functions and 10 GB for container images, so teams hitting a size wall on an individual function gain no relief. Operational benefits include faster function activation after creates and updates by eliminating Lambda's intermediate copy step, though the deployment workflow still requires calling UpdateFunctionCode after replacing the S3 object, and Terraform support via an s3_object_storage_mode attribute remains pending.
