You can license vSphere 5.5 individually or as part of vCloud Suite 5.8. You should consider the licensing and integration options that are available to you.
Some vCloud Suite components are available as standalone products that are licensed on a per-virtual machine basis. When the products are part of vCloud Suite, they are licensed on a per-CPU basis. You can run unlimited number of virtual machines on CPUs that are licensed with vCloud Suite.
You can combine the features of vSphere 5.5 with other components of vCloud Suite to leverage the full capabilities of the software-defined data center. For more information, see vCloud Suite Architecture Overview and Use Cases.
Not all features and capabilities of vSphere are available in all editions. For a comparison of feature sets in each edition, seehttp://www.vmware.com/products/vsphere/.
