I'm on DigitalOcean and I have a very simple scenario for my website.Now having 3000 concurrent hits every minutes. (For example)Currently it is directly on 1 only single Apache Server.The website CAN NOT be Cached. (for some sensitive reason)Then I am thinking for simply advanced setup, like:1x Software Load Balancer (e.g, Nginx)3x Apache as Web Servers .. at behind LB.Then suddenly my simple (but BIG) questions are:Load Balancer or Web Servers. Which ones should have better CAPACITIES, in terms of BANDWIDTH and PERFOMANCE.Lets say LB redirects 1000 connections to each Web Servers. Does it mean:The LB still need to consume 3000 Traffic Bandwidth IN+OUT?Each WebServer still need to consume 1000 Traffic Bandwidth IN+OUT?LB should have big PROCESSING performance? Or, the WebServers?To be more dummy ..Something like ..Do I need to buy $80 / month for LB Droplet (and, leave $20 Droplets for WebServers)?(or) Do I need to buy $40 / month 3x WebServer Droplets (and, leave $10 Droplet for LB)?
Capacities on Load-balancer & Web Servers? Bandwidth + Performance
