In communication with components of a cloud platform, namely a software-defined network constructed to overlay at least one public cloud network, a controller features a virtual processor and a data store. The data store includes network address translation (NAT) processing logic configured to determine whether a control plane message from tenant resources is associated with a network address overlapping condition, which represents a first network address included in the control plane message overlaps a network address range relied upon by either (a) at least one of the components of the cloud platform or (b) a component associated with other tenant resources. The NAT processing logic is further configured to alter routing data stores that maintain routing information for each of the components of the cloud platform to substitute the first network address with a first virtual network address for subsequent data message routing.

Controller-based traffic filtering and address modification

A computerized method for avoiding cross-region communications when utilizing a cloud overlay network is described. The method involves an operation of deploying one or more spoke gateways within at least a first region and a second region of a first virtual private cloud network. Thereafter, a region and a virtual private cloud network associated with a source and a destination of a communication are determined. Upon determining that the destination of the communication resides within a second virtual private cloud network, which is different than the first virtual private cloud network, the routing of the communication between the source and the destination is controlled by one or more spoke gateways solely residing within the region in which the source.

Global multi-cloud overlay network with regional preference

A controller configured to maintain a global virtual private cloud network (global VPC), which comprises a plurality of regions including a first region and a second region. The first region features at least a first workload and a first spoke subnetwork including a first set of spoke gateways. The second region features at least a second workload and a second spoke subnetwork including a second set of spoke gateways. These sets of spoke gateways are part of the cloud overlay network. Responsive to the first workload operating as a source for transmission of a first message to a first destination external to the global VPC, the logic is configured to (i) direct the first message from the first workload to a spoke gateway of the first set of spoke gateways residing withing the first region and (ii) preclude transmission of the first message to the second spoke subnetwork.

Controller for region-based management of a multi-cloud overlay network

A multi-cloud overlay network for supporting communications between a first public cloud network and a second public cloud network. The overlay network features a management virtual private network, which includes a network load balancing (NLB) component and a controller registered as a target on a port of the NLB component. The overlay network further includes one or more spoke or transit gateways and a multi-cloud access virtual private cloud (VPC) operating within the first public cloud network, and a remote cloud load balancer component operating the second public cloud network. The remote cloud load balancer component is communicatively coupled between the multi-cloud access VPC and one or more remote spoke or transit gateways. The multi-cloud access VPC includes a VPC endpoint that is assigned a private IP address and communicatively coupled to the NLB component and a virtual private network (VPN) gateway communicatively coupled to a private transport.
