The first area of optimization is between the member and PoP traffic in this last mile normally traverses over the public internet. How Points of Presence (PoPs) accelerate HTTP The following animation illustrates some of the advantages of leveraging a close-by PoP versus a far-away data center.įig 2. By migrating to AFD, we’re able to extend our reach to 300 PoPs, many in countries where we had no PoP presence previously. We started out by building our very own in-house CDN (Content Delivery Network) for dynamic content, spanning 19 PoPs across 10 countries. To minimize this, HTTP proxies are distributed geographically in points of presence (PoPs) closer to member last mile networks. data centers would introduce significant latency. Because of the geographic distance between some members and our data centers, sending members directly to one of our U.S.
There are hundreds of impacting parameters, but the one with the most impact is the latency between the server and the client. The three different internet “miles” that traffic flows amongĪccelerating this byte stream is complex because the disciplines involved span physical infrastructure and software stacks across the network, hardware, and application spaces. Data flows from our data centers (first mile), through the internet (middle mile), and is then handed off to the member’s ISP (last mile).įig 1.
How do Points of Presence (PoPs) accelerate traffic? The bytes that make up the LinkedIn experience are delivered to your devices from LinkedIn’s U.S. In this blog post, we’ll explain some of the technology that runs the edge, further explore the performance wins we’ve seen, and recap interesting challenges from this multi-year migration. Being on Azure has also enabled us to streamline our site operations and start redesigning our infrastructure for greater scalability. We also continue to ramp up additional LinkedIn web properties like Real-Time Bidding and the lnkd.in URL shortener.
Microsoft has continued to aggressively expand the AFD footprint to new countries, giving us quick and direct access to our members’ ISPs, which has resulted in measurable latency improvements, especially in Africa. We announced the completion of LinkedIn’s migration to Azure’s edge offering, Azure Front Door (AFD), in June of 2020 and since then we have seen numerous benefits from the switch.
