AWS Certified Data Engineer - Associate

Architects also need to consider performance when selecting compute, storage, database, and networking solutions. The appropriate architecture depends on application requirements, workload patterns, latency, and expected traffic.

Storage Solutions

AWS provides different storage services for different types of workloads. Amazon S3 is designed for object storage, Amazon EBS provides block storage for EC2 instances, and Amazon EFS provides scalable file storage.

Architects must consider factors such as performance, accessibility, durability, scalability, backup, and cost when selecting storage technologies.

For example, S3 may be suitable for storing documents and backups, while EBS can be used for applications that require block-level storage attached to EC2 instances.

Database Selection

Selecting the right database is another important architectural decision. AWS provides relational and NoSQL database technologies for different application requirements.

Relational databases can be useful for structured transactional workloads, while NoSQL databases may be appropriate for applications requiring flexible schemas and high scalability.

Architects should consider performance, availability, consistency, scalability, backup, recovery, and operational requirements before choosing a database solution.

Cost Optimization

Cloud architecture must balance technical performance with financial efficiency. AWS provides multiple ways to optimize cloud spending.

Architects can evaluate resource utilization, storage classes, scaling strategies, and purchasing options to reduce unnecessary costs.
