Real-world scenario
The first nightly CSV export arrives. You upload it to S3 as an object with a dated key so downstream jobs can find the latest file.
By the end you can:
Follow the request/data flow through the architecture.
Work through each concept and mark it understood. This unlocks the knowledge check.
Object storage with 11 nines of durability and effectively unlimited capacity.
Why it matters
The backbone of data lakes, static sites, backups and pipelines.
When to use it
Use for objects/blobs. Use EBS for block (a disk for one instance) and EFS for shared file systems.
Example
aws s3 cp ./report.pdf s3://my-bucket/reports/ \ --storage-class INTELLIGENT_TIERING --sse aws:kms
Gotcha (exam trap)
S3 is private by default — public exposure is almost always a misconfigured policy or disabled Block Public Access, not an S3 flaw.
Use the simulated AWS console below to complete each mission step. No real AWS account is required.
In the "etl-exports-bleepx" bucket, upload an object with the key "sales/2026-01-15.csv" and a few rows of CSV content.
