But in the spirit of trying to be helpful, I will echo the sentiments I've seen elsewhere in this thread and say your best bet will be a reasonably sized box running HAProxy fronting at least 2 boxes running nginx + your API code. Since it is highly likely you have a DB you could also run an "internal" HAproxy box fronting multiple postgres servers that are doing bidirectional data sync but that complexity ramps up QUICKLY.
