AWS Lambda's Self-Managed Code Storage Lifts the Account Quota, Not the Function Size Limit
InfoQ, Thursday, July 30th, 2026
AWS Lambda now supports self-managed S3 code storage, removing account quotas but keeping per-function size limits.
AWS announced self-managed code storage for Lambda, allowing functions to reference deployment packages directly from customer-owned S3 buckets instead of Lambda-managed storage.
The change eliminates the per-Region code storage quota that large function fleets previously needed support tickets to raise, while the default Lambda-managed limit goes from 75 GB to 300 GB.
Individual function package limits are unchanged: 50 MB zipped and 250 MB unzipped for zip functions, 10 GB for container images.
The update shifts storage costs to visible S3 line items and removes intermediate package copies, potentially speeding function activation after updates.
