VM setup

For the test and qa platform, as well as for the initial pilot platform the following generic setup will be used as described below.

VM pairs

A total of 3 pairs of VMs, 6 in total is allocated.

Each pair has a distinct role in the setup:

• The LB* nodes represent the nodes that handle load balancing and https termination. LB nodes do not share any state
• The COAA* pair of nodes provide vhosts for comanage, saml aa and voot vhosts, and has a MySQL database with runs in master/master configuration. COAA nodes share state using the MySQL database.
• The TEIP* pair of nodes provide a vhost for the TEIP service and have a MySQL database which runs in master/master configuration. TEIP nodes share state trough the MySQL database

VM naming

Depending on the physical platform used, the VMs will have technical names 

lb1.{dev|test|pilot}.vopaas.geant.org

lb2.{dev|test|pilot}.vopaas.geant.org

coaa1.{dev|test|pilot}.vopaas.geant.org
