as per you mentioned, you can not use the use case i mentioned. you need to have a load balancer for split the load between web servers,
this can be only be done based on the server capacity. based on requests server handling.
Internet speed you need on a server-side that is based on hosting provider - so better buy an easy flex plan with AWS or any other provider based on the requirement so you can dynamically increase the capacity ( example, seasonal sale you need mode bandwidth and compute, and rest not)
