The basics, in plain English

Storage is simply where your data lives in the cloud. Different jobs need different kinds of storage: big buckets for files like images, fast disks attached to servers, and databases for organized, searchable information.

Storage
Any place the cloud keeps your data so you can get it back later.
Object storage
A giant bucket for files like photos, videos, and backups, reached over the internet.
Block storage
A virtual hard drive you attach to a server for fast, local-feeling access.
Database
Software that stores data in an organized way so you can search and update it quickly.
SQL vs NoSQL
SQL stores data in neat tables; NoSQL is more flexible for less structured data.
Backup
A saved copy of your data you can restore if something goes wrong.

Where data lives

Object storage (S3) for blobs, block (EBS) for disks, managed databases (RDS, DynamoDB) for structured data. Managed means less ops, more cost.
