AWS Certified Developer - Associate

Availability Zones, load balancing, Auto Scaling, backups, and redundant resources can be combined to reduce single points of failure.

For example, an application can run across multiple Availability Zones and use a load balancer to distribute traffic. If one resource becomes unavailable, traffic can be redirected to healthy resources.

Understanding these architecture patterns is an important part of Solutions Architect – Associate preparation.

Scalability and Performance

Application traffic can change significantly depending on business conditions. A scalable architecture should be able to handle increased demand without requiring excessive manual intervention.

AWS Auto Scaling can adjust resources according to workload requirements, while load balancing distributes traffic across available resources.

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.
