Multiple enterprises (tenants) consuming resources in a public Cloud
shares the physical infrastructure of one or more DCs out of which
the Cloud resources are serviced. Hence one of the major features
that has to be supported in public Cloud DCs is multitenant
isolation, which is realized via various DC isolation technologies,
such as VLAN or VxLAN. In a hybrid Cloud environment where a public
Cloud (more specifically off-premises public Cloud resources acquired
by a tenant ) becomes an _extension_ of a tenant intranet or private
Cloud, the multitenant isolation capability has to be extended beyond
the public Cloud DCs. The multitenant isolation _domain_ has to span
end-to-end from the tenant network or on-premises resources via the
MAN/WAN and the public Cloud DC networks to tenant off-premises
resources. While multitenant isolationI isolates one tenant from
another (inter-hybrid Cloud isolation), an enterprise may desire
controlled connectivity to a hybrid Cloud from another Cloud or
network or tenant or select resources. In addition, there may be
need for controlling direct reachability of resources within a hybrid
Cloud itself (intra-hybrid Cloud). The tenant network may be
connected to the public Cloud (DCs) over the Internet or a private
IP/MPLS MAN/WAN owned or operated by a service provider, which also
may support PPVPN (Provider Provided VPN) service, such as the L3
MPLS VPN. In this work we consider the latter type of network and
describe a framework for supporting inter-hybrid Cloud multitenant
isolation, inter-hybrid Cloud connectivity and intra-hybrid Cloud
reachability.
