Serverless platforms often limit payload and file sizes passed directly to functions. These limits encourage using object storage for large data instead. Functions then process files by reference, not direct upload. This separation improves performance and scalability. While initially confusing, it leads to cleaner system design.
Design constraints prevent inefficient data handling. Systems scale more reliably.
This pattern reinforces best practices for handling large datasets in the cloud.
Serverless functions have strict payload size limits.
