In a recent project, I had to integrate my site with the Amazon s3 storage. The entire files directory contents were being transferred there. So, every time I wanted to check something, I had to log in to the AWS console and select the bucket and had to scroll way down to get the correct files/folder. I found it very time-consuming, as I have more than 2000/3000 folders inside. It was then, I came to know about something called "DragonDisk".
Finding the way to store ,distribute and manage the data are big challenge. We know that the building and maintaining our own storage repository is expensive and time consuming. Amazon Simple Storage Service (amazon-s3 is the better way) provides developers and IT teams with secure, durable, highly-scalable object storage
