Multiple Cloud Foundation instances can be managed together by grouping them into a federation, such that each member can view information about the entire federation and the individual instances within it. Federation members can view inventory across the Cloud Foundation instances in the federation as well as the available and used aggregate capacity (CPU, memory, and storage). This allows you to maintain control over the different sites and ensure that they are operating with the right degree of freedom and meeting compliance regulations for your industry. It also simplifies patch management by showing the number of patches available across sites in the global view.
