2.3. Core AWS Services: Storage

Storage services are fundamental to any application, providing a place to store data persistently. AWS offers a wide range of storage services, each designed with distinct first principles to cater to different data access patterns, durability needs, and cost requirements.

💡 First Principle: The First Principle of AWS storage is to provide highly durable, scalable, and cost-effective options for diverse data types, enabling users to choose the right solution for their data while shifting the burden of hardware management to AWS. This allows businesses to store virtually any amount of data.

This section provides a high-level overview of the most common AWS storage services: Amazon S3, Amazon EBS, Amazon EFS, and Amazon S3 Glacier.

Scenario: A company needs to store various types of data: website images, server boot volumes, shared application files, and long-term backups.

Reflection Question: How do diverse AWS storage services (e.g., S3, EBS, EFS) fundamentally enable businesses to choose the right solution for their data based on access patterns, durability, and cost, while simplifying storage hardware management?

💡 Tip: Focus on the primary purpose and use case for each storage service: object, block, or file storage.
