handling file uploads in Nodejs with AWS

I have a server in Node.js and say I have a POST request that uploads a multipart file to my server and then I upload it to AWS S3.

The issue is, with multer, I have to save the file to disk first.

If I deploy my server onto EC2 then how will file uploading work as it won't have a destination to temporarily store the file?

Thanks!
