What are Amazon S3 and Azure Blob Storage?

Options

1. Cloud object storage for files such as images, backups and logs (Correct option)
2. Managed relational databases that are queried with SQL
3. Container orchestrators that schedule workloads on nodes
4. CI servers that build and test the code of a project

Answer

Cloud object storage services for files such as images, backups and logs

Why

Object storage keeps files (objects) in containers called buckets (S3) or containers (Azure Blob), each reachable by a key or URL.

Amazon S3 = Simple Storage Service. Typical uses: images and videos for an app, backups, data lakes, static websites.

It is not a database: you do not query it with SQL, you store and retrieve whole files.

Remember

S3 / Blob = cloud storage for files.
