actually whats wrong with bare metal servers?

  Nothing, if you have a need for a single big app that can consume the full system. Makes redundancy more complex as you cannot move the app if there is a failure. Requires clustering, SLB type design.

    i'm thinking a cluster of bare metal servers is rather simpler than a cluster of containers on top of the same number of bare metal servers?

      What are you trying to do is the key here. Lets say you have some web servers and you also have some applications (games). The load on the games depends on the number of users, how popular it is. If you have a a few racks of servers that are all 100% the same that you can bring up the containers on demand. Have web containers. Have game containers on demand based on load. Bare metal is really for something where you have a reason to consume all the HW, lets say for a DB you want to keep all the set in memory, then bare metal in a cluster with a big box that has lots of RAM. Like I said it is all really use case dependent. The trend today in the target scale systems is load on demand via, VM or container. Also if you use containers with a routing protocol on the server they can move and update the network as they move.
