Part IIa – Scaling & Updating Spring Contact App & vPostgres with vFabric Application Director
In part three of this 4-part series, we take the previously deployed application and initiate a scale out and update using vFabric Application Director 5.0. We start with a button called "scale out" and add more nodes to the application-tier cluster, then click update. The new nodes come online automatically. Then, we change the WAR file values to 2.0 version of this app and make a minor update script modification. For more information on Application director see: www.vmware.com
