Ask HN: How are you using AWS to serve and scale your web app?
Which Amazon Web Services products are you using and what is your setup?
Do you scale your EC2 instances horizontally or do you find you can handle most bottlenecks by moving to a bigger instance?
Do you put your db in EBS, RDS, or just use EC2 storage? Why do you or do you not use RDS? How do you handle backups?
How do you share user uploaded files between web server instances?
Thanks!
