Hey otterley, thanks for your comment! The homogeneous server recommendation is based on experience running tens of thousands of containers (mixed application and database containers) in production. In that case, when you have lots more containers than you have servers, it makes sense to allow a system which can automatically distribute the load across those machines to do so, and getting the scheduling right for that automatic load distribution is easier with relatively (although not necessarily exactly) homogeneous machines. Of course, every deployment is different, and I'm not categorically saying "never have dedicated database hardware", just "clustering with automatic load balancing is easier with homogeneous hardware". :)
