Cloud File Storage
Definition
Storing user-uploaded files directly on your Node.js server (like the EC2 instance) is an anti-pattern because if the server scales or crashes, the files are lost. Instead, you should upload files directly to cloud storage like AWS S3 or Google Cloud Storage.

$ npm install aws-sdk multer-s3

// into the S3 bucket without ever saving it to your server's local hard drive.
