My client having website in magento where users comes and creates a tshirt online. On each tshirt creation, there are 6 different images created using code and total 300 to 400 unique designs created per day so almost 24000 images per day. Currently one hdd with 1TB is attached with two EC2 instances.
Now the problem is, client wants option which can scale automatically as 1 TB is also one day will be full.
Is there any system or architecture which can provide auto scalable option. I don't want to use S3 bucket instead of hdd.
