In representative embodiments, multiple cloud computing infrastructures, each having its own application and management fabric, coexist with in the same cloud computing infrastructure. This results in a cloud computing infrastructure where multiple management fabrics and application fabrics coexist to offer their own services and cross platform services. Each functions independently and also communicates with each other to offer high availability and disaster recovery. One application and management infrastructure is a host to the other application and management infrastructure. The hosted infrastructure accesses underlying fabrics through the host infrastructure. A resultant system comprises a common hardware fabric, a common runtime, and a service fabric comprising services from both the host and hosted infrastructures.
