Are you sure you need such a setup? IMHO the bottleneck usually is the 4D database server which unfortunately still is single threaded. If your 4D database fits on a SSD, that alone could be enough to handle much higher loads without slowing down. If you serve big amounts of static content, aka. pictures, movies, pdfs etc. simply putting your A4D webserver behind an apache proxy and letting apache serve the static content will help in this scenario. If you do a lot of 4D/A4D calculations to generate your content, then 4D clients as web servers might be necessary, but as you mentioned you need a load balancer. Don't have experience in this scenario. Anyhow for all scenarios above a single powerful machine running ESXi or Xen or other hypervisor might be cheaper/easier to maintain/more flexible than several individual servers. You didn't mention, which country you prefer your servers to be hosted. While the internet works world wide, choosing a provider geographically close to your customers can be beneficial.
