摘要： A scalable multi-cluster resource sharing facility. A global witness process runs on a first computing platform that communicates over one or more networks to any number of nodes situated over two or more clusters. The global witness process listens on the network for occurrences of leadership and/or resource requests from nodes of different clusters. The global witness processes a request by retrieving a resource request and a respective last known state value, comparing the last known state value to a global stored state value, then storing a new state value when the respective last known state value is equal to the stored state value. Any number of contemporaneous requests can be processed by the global witness process, however only one request can be granted. The other requestors each receive a rejection of their resource request when their proffered last known state value is not equal to the stored state value.

摘要： Methods, system, and computer program product for implementing an address translation service that uses nondenominational address handles instead of IP addresses between private cloud domain and public cloud domains. The address translation service can be implemented to enable a data-center running in a private cloud domain to communicate with the public cloud domain data-center over load balancers. In addition, the address translation service ensures that all services that need to communicate across data-centers can be reached over load balancers. As such, to avoid conflicting subnets used by a data center from the private cloud domain and the public cloud domain, services in the public cloud domain use a private cloud load balancer to connect with the services in a private cloud domain. Similarly, a public cloud load balancer is used to connect with services in the private cloud domain.
