Final answer:
To accomplish the task of designing an e-commerce website with the lowest latency and best performance for shoppers, Jack should use a Content Delivery Network (CDN) and a cloud-based infrastructure. He should also optimize the website's code and implement performance-enhancing techniques.
Step-by-step explanation:
Jack should use a Content Delivery Network (CDN) to accomplish the task. A CDN is a distributed network of servers located across different geographic locations.
By caching the website's static content on these servers, the CDN reduces latency and improves the website's performance for shoppers around the globe.
Additionally, Jack should consider using a cloud-based infrastructure, such as Amazon Web Services (AWS) or Microsoft Azure, which provide global server presence and scalability to handle high traffic volumes.
Finally, he should optimize the website's code and implement techniques like minifying files, compressing images, and using caching mechanisms to further enhance performance.
