How did John Mosquera ensure the system's ability to handle peak transaction loads during high-traffic events like Black Friday?

To handle peak transaction loads, John Mosquera implemented several strategies. He designed the system architecture to be horizontally scalable, allowing for easy addition of resources. Auto-scaling was set up to automatically adjust capacity based on traffic. John implemented caching mechanisms to reduce database load during high-traffic periods. He used queue-based processing for non-critical tasks to prevent system overload. Load testing was conducted to simulate peak conditions and identify bottlenecks. John also implemented traffic shaping and rate limiting to prevent any single source from overwhelming the system. A content delivery network (CDN) was used to distribute static content and reduce server load. John ensured the system's ability to handle peak loads through horizontal scalability, auto-scaling, strategic caching, queue-based processing, and comprehensive load testing. These measures, combined with traffic management and CDN usage, enabled the payment system to maintain performance and reliability even during high-traffic events like Black Friday.
