Resumen
When it comes to achieving performance, reliability, and scalability for commercial-grade Web applications, people see that the limiting bottleneck is the middle mile, or the time data spends traveling back and forth across the Internet, between the origin server and end user. From the end user's point of view a robust first mile is necessary, but not sufficient, for achieving strong application performance and reliability. This is where the middle mile comes in. The prevalence of Internet reliability and peering-point problems means that the longer data must travel through the middle mile, the more it is subject to congestion, packet loss, and poor performance. Speeding up round-trips is a complex problem, but many optimizations are made possible by using a highly distributed infrastructure. Here are some ways: 1. Reduce transport-layer overhead. 2. Find better routes. 3. Prefetch embedded content. 4. Assemble pages at the edge. 5. Use compression and delta encoding. 6. Offload computations to the edge.
