AWS
The following diagram shows the architecture of the clusters setup in AWS.
The setup of clusters in AWS follow the general guidelines of other OpenShift installations, with the following caveats.
The setup of OpenShift clusters in AWS uses as much of the standard AWS infrastructure as possible, and follows some best practices recommended by Red Hat. |
Network
The network is divided into two main sections in a VPC:
-
Public subnet
-
Private subnet
Availability Zones
AWS supports three (3) availability zones per region. OpenShift clusters in AWS might be replicated across either one (1) or (3) zones, depending on the availability or cost requirements.
Load Balancers
There are two (2) kinds of load balancers:
-
Master LB
-
App LB
All load balancers are ELB instances provided by AWS.
From the perspective of mungg-provision-aws, all three LBs are equal. |
