[Verse 1] When traffic comes flooding to your website door One server alone can't handle much more That's when you need a traffic cop so wise A load balancer to distribute the prize [Chorus] Balance the load, spread it around Layer Four and Seven, both are sound Round Robin, Weighted, Least Connections too Health checks keep your servers running true Balance the load, that's what we do [Verse 2] Layer Four looks at the network frame IP addresses and ports are the game It's fast and simple, routes by connection No peek inside for content inspection [Chorus] Balance the load, spread it around Layer Four and Seven, both are sound Round Robin, Weighted, Least Connections too Health checks keep your servers running true Balance the load, that's what we do [Verse 3] Layer Seven reads the HTTP request Looks at URLs and headers for the best Smart routing based on what's inside Sticky sessions keep users tied [Bridge] Round Robin goes one by one in line Weighted gives more to servers that shine Least Connections finds the one that's free Random picks one randomly [Verse 4] Health checks ping your servers every minute If one goes down, take it out of the limit Only healthy servers get the flow Keep your users happy, let performance grow [Chorus] Balance the load, spread it around Layer Four and Seven, both are sound Round Robin, Weighted, Least Connections too Health checks keep your servers running true Balance the load, that's what we do [Outro] From single server to a farming fleet Load balancing makes your system complete Traffic flows smooth, no bottleneck blues Balance the load, you just can't lose
