-* Webserver: Holds one or more webserver instances that represent the public facing part of the architecture. Only instances running in this tier should have a public IP assigned.
36
-* Database: Instances handling all operations related to persistence. Must be reachable by the "Instance" and "Balancer+Group" tier.
37
-* Instances: Space where all instances, that are not grouped, live.
38
-* Balancer+Group: Analytics instances grouped and managed by an Elastic Load Balancer. A group is just a term describing multiple instances replicating from one master instance. The word "group" does in this context not refer to the so called "Placement Groups".
