Varun's response lacks focus on the technical aspects of designing a microservices architecture. He primarily discusses Agile methodologies and hybrid environments without addressing key elements like identifying core functionalities, leveraging cloud services, or defining API contracts. The benchmark response highlights specific strategies for scalability and modularity, such as using AWS for auto-scaling and implementing RESTful APIs. Varun should focus on these technical details and provide examples of how he would apply them to ensure a robust microservices architecture.
