IAM

Contents returned from Bucket

Why?

• To better understand Amazon's object storage system accessible via internet, cli & REST/SOAP APIs.
• As an intro to AWS SDKs

What?

• S3 (Simple Storage System) can be plainly understood as an object storage system.
• S3 stores & protects assets for websites, apps, IoT devices, analytics etc
• S3 uses Buckets which are roughly equivalent to folders
• Inside of a Bucket is data for retrieval - in this example I retrieved a copy of my CV (henryStockdale.pdf) from a Bucket (first-bucket-test1)

Important lessons learnt

• AWS IAM: Identity and Access Management

• IAM is broken down into the following sections

  • Groups
  • Users
  • Roles
  • Policies

• Best Practise dictates definining permission on the Group level and affording said permission to inidividual Users by adding the latter to the former.

• Setting up IAM in this way, a User profile was made inheriting from its group the requisite permissions to access s3 Buckets.

• Both accessKeyId and secretAccessKey were stored as environment variables on my machine.
