Technology Modelling

Clustering is a physical architecture decision that we capture in the Physical Technology Layer. How you model it depends on how the clustering technology works.
Ideally, the application and information deployments are unaware of the physical nodes that make up the cluster.
To model a cluster where the application and information is deployed just to the cluster node:
  • Define a Technology Node for the cluster as a unit
  • Deploy Application Software Instances, Information Software Instances etc. to this Node as required
  • Define a sub-Technology Node for the actual physical hardware devices that are used to make up the cluster, e.g. the servers
    • Deploy the Hardware, Infrastructure Software instances as required to these sub nodes
In scenarios where the application and information instances must be manually deployed to each node in the cluster:
  • Define a Technology Node for the cluster as a unit
  • Deploy Application Software Instances, Information Software Instances etc. to this Node as required
  • Define a sub-Technology Node for the actual physical hardware devices that are used to make up the cluster, e.g. the servers
    • Deploy the Hardware, Infrastructure Software instances as required to these sub nodes
    • Deploy Application Software and Information Store instances to the sub-nodes.
