DynamoDB

A fully managed NoSQL database you use through AWS API calls.

Think of it as: A giant labelled locker wall where you fetch lockers by their exact key.

What to know for Level 0

Every read and write is a signed HTTPS API call (GetItem, PutItem, Query) to a public endpoint, approved by IAM. No connections, no passwords, no security groups.
Items are found by their key, so you design tables around how you'll read them. There are no joins. It's ideal for lookups by id at any scale.
No servers to size or patch: you manage tables, keys and who may access them.

More detail

There’s no server and no connection to open. Every read and write (GetItem, PutItem, Query…) is an HTTPS call to a public AWS endpoint, and IAM approves each one. Items are found by their key, so you design tables around how you’ll read them.
