Azure has no equivalent of S3 Object Lambda, and Object Lambda itself has been closed to new customers since Nov 7, 2025. On both clouds, put a function or CDN logic in front of the storage instead.
- AWS's suggested alternatives include CloudFront with Lambda (for example, the Dynamic Image Transformation solution) or calling Lambda directly. On Azure, the usual pattern is Azure Functions behind API Management or Front Door, reading from Blob Storage.
