Final answer:
Amazon CloudFront uses a Content Delivery Network (CDN) to ensure low latency and fast content delivery to users across the globe. CDNs distribute content from servers close to the user's location, enhancing speed and performance.
Step-by-step explanation:
Amazon CloudFront utilizes a Content Delivery Network (CDN) to distribute content to global users with low latency. A CDN consists of a network of servers strategically located around the world, allowing content to be delivered from the server closest to the user. This results in faster load times and a more seamless experience for the user by reducing the physical distance that the data needs to travel.
While a Domain Name System (DNS) is used for resolving URLs to IP addresses, a Virtual Private Network (VPN) creates a secure network over the internet, and an Internet Service Provider (ISP) is a company that provides internet connectivity, none of these technologies are specifically used by CloudFront to reduce latency. Instead, CloudFront's integration of CDNs is the primary means to achieve its goal of fast content delivery to users worldwide.
