I want to use AWS auto-scaling but I have a question about the files present in the Volume. I’ll explain it better below:

1 – I want to scale my application made in PHP with MYSQL database.

2 – The Database must be unique using RDS so that new EC2 instances can save and use the same data without losing information.

3 – The question is about the new EC2 instances, whether they will have their own Volume or will have to be made a single scalable Volume like the RDS solution for MYSQL.

4 – Some information, such as profile image, is saved in the EC2 Volume, so my question is that when generating several EC2s via Auto-Scaling, this information will be lost or not found by my App?

Thanks
