Creating a S3 Bucket on AWS and Presigned URLs

AWS BUCKET S3

Amazon S3 (Simple Storage Service) is a scalable, durable, and secure cloud storage service offered by AWS (Amazon Web Services). It allows users to store and retrieve any amount of data, from anywhere in the world, at any time. Data in S3 is organized into buckets, which serve as containers for objects such as files, images, videos, or backups.

Key features of Amazon S3 include:

1. High scalability for managing large datasets.
2. Durability and availability through replication across multiple data centers.
3. Fine-grained access control using permissions and policies.
4. Integration with other AWS services like EC2, Lambda, and CloudFront.

Presigned URL

A Presigned URL in Amazon S3 is a secure, temporary link that grants time-limited access to a specific object in an S3 bucket without requiring additional authentication. Presigned URLs are typically used to share objects with users who do not have direct access to the S3 bucket or to enable temporary, programmatic access.

Key Features of a Presigned URL:

1. Expiration Time: The URL is valid only for a specified duration, ensuring temporary access.
2. Restricted Permissions: The URL can grant limited actions like GET (download), PUT (upload), or POST (multipart upload).
3. No Additional Authentication Needed: Recipients of the URL do not need AWS credentials to access the object.
