Download a file of size 1 GB using AWS Lambda

Question

I am trying to download a file from FTP server using.Net core 3.1 in AWS Lambda. But, maximum disk space available to a lambda function is 512 MB. Is there any way to download the file of size 1 GB in AWS Lambda?

Answer 1

For large files in a Lambda AWS has recently added support for EFS .

By using an EFS mount your Lambda(s) have access to persistent storage that will scale elasticly as your application demands it.

This will also last past any cold starts, new versions or across multiple Lambdas (and EC2 instances) at the same time.
