Configure your vRealize Business for Cloud installation for scalability in accordance with VMware guidelines.
vRealize Business for Cloud can scale up to 20,000 virtual machines across ten VMware vCenter Server instances. The first synchronization of the inventory data collection takes approximately three hours to synchronize 20,000 virtual machines across three VMwarevCenter Server instances. Synchronization of statistics from VMware vCenter Server takes approximately one hour for 20,000 virtual machines. By default, the cost calculation job runs every day and takes approximately two hours for each run for 20,000 virtual machines.
In vRealize Business for Cloud 1.0, the default virtual appliance configuration can support up to 20,000 virtual machines. Increasing the limits of the virtual appliance beyond its default configuration does not increase the number of virtual machines that it can support.
