Introduction to Amazon S3

• Simple Storage Service is storage for the Internet. It is designed to make web-scale computing easier.
• I can use to store and retrieve any amount of data

Advantages of using Amazon S3

• Creating buckets: bucket stores data, they are containers in Amazon S3 for data storage.
• Storing data: infinite amount of data in a bucket, I can Upload as many objects as I like into an Amazon S3 bucket, object can contain up to 5 TB of data.
• Downloading data: Download data or enable others to do it.
• Permissions: Grant or deny access to others who want to use data into Amazon S3 bucket.

Amazon S3 concepts

• Buckets
  • bucket is a container of objects stored in S3.
  • Buckets purpose: play role in access control, used for usage reporting, identify account responsible for storage and data transfer.
• Objects
  • entities stored in Amazon S3.
  • object consist of data and metadata.
  • metadata is name-value pairs describe the object.
  • identified in a bucket by a key and a version ID.
• Keys
  • identify object within a bucket.
  • object in a bucket has one key.
• Regions
  • geographical AWS Region where Amazon S3 will store the buckets created.
  • Region can optimize latency, minimize costs, or address regulatory requirements.
  • Objects stored in a Region never leave the Region to another one unless explicitly transferd.
• Amazon S3 data consistency model
  • provides strong consistency for PUTs and DELETEs of objects in Amazon S3 bucket in all AWS Regions.

Amazon S3 features

• Storage classes.
  • offers a range of storage classes designed for different cases.
• Bucket policies.
  • provide access control to buckets and objects based on conditions.
  • permissions attached to a bucket apply to all of the bucket’s objects that are owned by the bucket owner account.
• AWS Identity and Access Management.
  • AWS Identity and Access Management (IAM) manage access to Amazon S3 resources.
• Access control lists
  • control access to each bucket and object using an access control list.
• Versioning.
  • versioning keep multiple versions of an object in the same bucket.
• Operations, Common operations:
  • Create a bucket.
  • Write an object.
  • Read an object.
  • delete an object.
  • List keys.

Amazon S3 application programming interfaces (API)

• provides a REST and a SOAP interface.

The REST interface

• HTTP interface to Amazon S3.
• Using REST, use standard HTTP requests to create, fetch, and delete buckets and objects.
• REST API uses the standard HTTP headers and status codes, so that standard browsers and toolkits work as expected.

  The SOAP interface

• use document literal encoding.
• to use SOAP, download the WSDL.

Getting started

• go to your project directory and execute the command: amplify add storage
• a screen will prompt to fill info (I will do it ofc).
• push changes to the cloud, execute the command: amplify push
