It looks like, if you had a high-bandwidth site that was low in other overhead, it would be cheaper (about half the price, actually) to serve the site on a bunch of $5 or $10/month servers with a load balancer, rather than using a single, large container.
Is structuring a site to take advantage of the cheaper bandwidth a violation of the TOS? Would it be unneighborly? I can see it taking up too many IP addresses, but what other technical issues might it cause?
Problem is that if your load balancer is also a $5 or $10/month server, you only have 1TB or 2TB outbound bandwidth. Unfortunately it seems to me that you cannot use the sum of all of your droplets bandwidth on one of your droplets (which is your load balancer).
