Copy of Use Case Introduction

Welcome to the AWS Certified Solutions Architect - Associate Study Guide

In this study guide, we will explore real-world AWS architecture challenges, leveraging SecureCart, an e-commerce platform, as our use case to guide discussions, hands-on exercises, and scenario-based learning.

SecureCart will serve as a practical example to help us apply AWS best practices in security, scalability, performance, and cost optimization across multiple domains.


The SecureCart Use Case: A Cloud-Native E-Commerce Platform

SecureCart is a modern, cloud-native e-commerce application built on AWS, supporting millions of users globally. The company wants to:

  • Secure AWS resources and applications against potential threats

  • Design highly available and fault-tolerant architectures to handle peak shopping seasons

  • Optimize compute, storage, and database performance while maintaining cost efficiency

  • Implement cost-saving strategies while maintaining performance and reliability in AWS

We will solve real-world challenges that SecureCart faces as they scale their infrastructure, optimize operations, and secure customer data.


Study Guide Overview – Domains & Focus Areas

Domain 1: Design Secure Architectures

SecureCart must protect customer data, prevent security breaches, and ensure compliance while using AWS services.

  • Design Secure Access to AWS Resources (IAM, SSO, Multi-Account Security)

  • Secure Application Workloads (VPC Security, GuardDuty, WAF, Threat Protection)

  • Data Security & Encryption (KMS, ACM, Data Retention, IAM Policies)

Example Challenge: SecureCart wants to restrict developers from accessing production data while maintaining operational efficiency. What IAM strategy should they use?


Domain 2: Design Resilient Architectures

SecureCart must handle high-traffic loads, prevent outages, and ensure service availability.

  • Scalable and Loosely Coupled Architectures (Microservices, Event-Driven Design)

  • Highly Available & Fault-Tolerant Systems (Multi-AZ, Multi-Region, DR Strategies)

Example Challenge: During Black Friday, SecureCart’s database spikes, causing slow response times. How can we implement auto-scaling and caching strategies to prevent this?


Domain 3: Design High-Performing Architectures

SecureCart must optimize compute, storage, and networking performance while ensuring low latency and high throughput.

  • High-Performance Compute & Storage Solutions (EC2 Auto Scaling, Lambda, S3, EFS, FSx)

  • Database Performance Optimization (Aurora, DynamoDB, ElastiCache)

  • High-Performance Network Architectures (CloudFront, Global Accelerator, Direct Connect)

Example Challenge: SecureCart’s global customers experience slow page loads in certain regions. How can AWS edge networking improve latency?


Domain 4: Design Cost-Optimized Architectures

SecureCart must control AWS costs while maintaining performance, availability, and security.

  • Cost-Optimized Compute & Storage (Spot Instances, S3 Intelligent-Tiering, Auto Scaling)

  • Cost-Effective Databases (Aurora Serverless, Read Replicas, DynamoDB On-Demand)

  • Cost-Optimized Network Design (VPC Peering, NAT Gateway Optimization, CloudFront)

Example Challenge: SecureCart’s NAT Gateway costs are increasing with multi-AZ deployments. What alternative cost-effective strategy can reduce data transfer fees?
