Design a microservices architecture for an e-commerce platform that can handle high traffic during seasonal sales. Define key services, communication methods, and how you would ensure data consistency across services.

Utilize a service-oriented architecture with independent services for order management, inventory, user accounts, and payment processing; implement an API Gateway for routing and a message broker for asynchronous communication to ensure decoupling and event-driven processing. Scenario Pressure: How would you handle service outages and ensure high availability during a spike in traffic? Depth Trigger: Discuss the trade-offs of using eventual consistency versus strong consistency in your data management approach.
