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?
