Q & A

What is the main challenge addressed in the script regarding data storage?

The main challenge is finding a way to store, distribute, and manage large amounts of data effectively and efficiently, as the demand for storage continues to grow.

Why is building and maintaining your own storage repository considered expensive and time-consuming?

Building and maintaining a private storage system requires purchasing hardware and software, setting up complex processes, hiring staff, and regularly adding more capacity, all of which can be costly and time-consuming.

What are the risks of guessing how much storage capacity is needed in the future?

If storage needs are underestimated, data may not be accessible, and if overestimated, you might end up paying for excess capacity that remains unused.

How does Amazon S3 help solve the problem of predicting future storage needs?

Amazon S3 allows users to store as much data as they need without having to predict future storage requirements. The service scales automatically based on usage.

What ensures the safety of data stored in Amazon S3?

Amazon S3 ensures data safety by automatically making copies of objects across multiple devices and facilities, providing durability and redundancy.

Can you recover deleted data in Amazon S3?

Yes, Amazon S3 allows users to preserve, retrieve, and restore every version of every object in a bucket, helping recover data in case of accidental deletion or application failures.
