How would you design a system to handle a high volume of transactions for an e-commerce application? What architecture patterns would you use?

## Approach Start with identifying the requirements and scale, then discuss the chosen architectural pattern (microservices) and why it’s effective for scalability and maintainability. ## Complexities Consider eventual consistency for transactions and the challenges of distributed systems. ## Trade-offs - Microservices offer flexibility but can increase operational complexity; decide a balance that fits the use case.
