AWS Certified Data Engineer - Associate

Developers need to understand how applications interact with S3 using APIs and SDKs. They should also understand permissions, access policies, encryption, storage classes, and lifecycle management.

Properly designed S3 solutions can provide scalable and durable storage while supporting different application requirements.

Database Development on AWS

Applications often require databases for storing structured and unstructured information. AWS provides multiple database technologies for different workloads.

Amazon RDS supports managed relational databases, while Amazon DynamoDB provides a managed NoSQL database service.

Developers need to understand how to choose and use database technologies based on application requirements. Factors such as data structure, performance, scalability, consistency, and access patterns should be considered.

Understanding database integration is an important part of developing cloud-based applications.

APIs and Application Integration

Modern applications often communicate through APIs. AWS provides services and technologies that can support API development and integration.

Amazon API Gateway can be used to create and manage APIs, while Lambda can provide serverless backend functionality.

Applications can also use messaging and event-driven architectures to communicate between different components. This approach can improve scalability and reduce direct dependencies between application services.
