2.4. Developer Interactions with Databases & Storage

For developers, interacting with databases and storage services is fundamental to building applications that manage data. This phase focuses on how developers integrate their applications with core AWS data services.

The First Principle is to choose the right data service based on your application's data model and access patterns, and then interact with it efficiently and securely using AWS SDKs or APIs. This ensures your application's data persistence layer is scalable, performant, and reliable.

You will learn about common developer interactions with Amazon RDS for relational data, and Amazon S3 for object storage.

The focus is on comprehending how to code your application to work with these services and why specific choices are made from a developer's perspective, which is crucial for the DVA-C02 exam.

Scenario: You're building a web application that needs to store structured user data (e.g., user profiles, orders) and unstructured data (e.g., user-uploaded photos).

Reflection Question: How do you choose the appropriate AWS data service (e.g., RDS for structured data, S3 for unstructured) and interact with it effectively using AWS SDKs to ensure your application's data persistence layer is scalable and performant?
