Task Statement 2.1: Design Scalable and Loosely Coupled Architectures

This study group guide will explore scalable, event-driven, and microservices-based architectures using AWS best practices. We will follow SecureCart, an e-commerce platform, as they transition from a monolithic to a highly scalable and distributed architecture using AWS services.

By the end of this study group, learners will be able to: ✅ Design scalable, event-driven, and microservices architectures ✅ Choose the right AWS managed services for loose coupling ✅ Implement caching, messaging, and workflow orchestration ✅ Optimize applications using containerized and serverless approaches
