Storage

Amazon S3

Object storage built to retrieve any amount of data from anywhere.

Overview

Simple Storage Service (S3) stores objects (files + metadata) inside buckets with 11 nines of durability. It supports versioning, lifecycle policies, encryption, static website hosting and event notifications.

When to use it

Storing static assets, backups, data lake files
Hosting static websites and SPA builds
Persisting test artifacts: logs, screenshots, videos, reports
Data lake landing zone for analytics

Setup

Console → S3 → Create bucket. Pick a globally unique name and region.
Decide Block Public Access (keep ON unless serving public web content).
Enable Versioning and Default Encryption (SSE-S3 or SSE-KMS).
Set up Lifecycle rules (e.g. move to Glacier after 90 days).
Attach a Bucket Policy or use IAM for access.

How to use

Upload a file

aws s3 cp report.html s3://my-bucket/qa/reports/

Sync a folder

aws s3 sync ./screenshots s3://my-bucket/qa/screenshots/

Generate a presigned URL

aws s3 presign s3://my-bucket/qa/reports/index.html --expires-in 3600

QA use cases

Publish HTML test reports (Allure, Playwright) to a private bucket and share via presigned URLs.
Store baseline images for visual regression testing.
Trigger a Lambda via S3 event when a new build artifact lands to kick off automated tests.
