I personally use Apache with mod_wsgi, in multi-processes mode (from 1 to 16, based on vCPU count). I know it's probably not the most "modern" option, but I know it, it works pretty well and I didn't notice any problem (I use a PostgreSQL ZODB with RelStorage and SQLAlchemy together). I also used GUnicorn for a while, but only for async-based applications...
