AWS Certified Solutions Architect Associate SAA-C03 Practice Question

A company is building an e-commerce application that must scale to handle sudden spikes in traffic during sales events. The application consists of a web front end that interacts with a back-end order processing system. The company wants to design an architecture that is scalable and minimizes the impact on other components if one component fails. What is the best architectural pattern to achieve this?

  • Use a tightly coupled multi-tier architecture with direct service-to-service communication.

  • Implement a monolithic architecture on Amazon EC2 Auto Scaling groups.

  • Deploy the application on a single large EC2 instance to handle peak loads.

  • Use a microservices architecture with services communicating via message queuing service such as Amazon SQS.
