Application routing infrastructure for private-level redirect trapping and creation of NAT mapping to work with connectivity in cloud and customer networks
A computer program product, system, and computer implemented method for application-level redirect trapping and creation of NAT mapping to work with routing infrastructure for private connectivity in cloud and customer networks. The approach disclosed herein generally comprises a method of leveraging a reverse connection endpoint and IP address mapping controller to capture redirection messages from a private cloud or network (e.g., a service consumer network or a service consumer hybrid cloud). This allows at least the IP address mapping controller to manage a cloud networking infrastructure to provide for a service provider network (e.g., a public cloud) to support applications that overcome the isolation requirements of a private cloud or network to perform useful work. For example, without saddling the private cloud or network user with a heavy pre-configuration burden, the approach disclosed herein supports redirection to dynamically determined IP addresses at the private cloud or network.
1. A computer-implemented method comprising:
identifying a reverse connection endpoint (RCE) at a service consumer network;
initiating a connection with the service consumer network using the RCE;
trapping a redirection message from the service consumer network at a cloud networking infrastructure layer; and
configuring the cloud networking infrastructure layer to route corresponding communications to the service consumer network.
2. The computer-implemented method of claim 1 , wherein initiating the connection with the service consumer network using the RCE is in response to a request received from a service provider application in a service provider network.
3. The computer-implemented method of claim 1 , wherein the redirection message includes a service IP address in the service consumer network that is different from an IP address for the RCE.
4. The computer-implemented method of claim 3 , wherein configuring the cloud networking infrastructure layer to route corresponding communications to the service consumer network comprises at least updating a network address translation table to include a mapping between a mapped IP address and the service IP address.
5. The computer-implemented method of claim 4 , wherein a service provider application in a service provider network exchanges one or more messages with a service consumer application using the mapped IP address.
6. The computer-implemented method of claim 5 , wherein the mapped IP address is returned to the service provider application.
7. The computer-implemented method of claim 1 , wherein the service consumer network comprises a private cloud or network and a service provider network comprises a public cloud or network.
8. A non-transitory computer readable medium having stored thereon a sequence of instructions which, when executed by a processor causes a set of acts comprising:
identifying a reverse connection endpoint (RCE) at a service consumer network;
initiating a connection with the service consumer network using the RCE;
trapping a redirection message from the service consumer network at a cloud networking infrastructure layer; and
configuring the cloud networking infrastructure layer to route corresponding communications to the service consumer network.
9. The non-transitory computer readable medium of claim 8 , wherein initiating the connection with the service consumer network using the RCE is in response to a request received from a service provider application in a service provider network.
10. The non-transitory computer readable medium of claim 8 , wherein the redirection message includes a service IP address in the service consumer network that is different from an IP address for the RCE.
11. The non-transitory computer readable medium of claim 10 , wherein configuring the cloud networking infrastructure layer to route corresponding communications to the service consumer network comprises at least updating a network address translation table to include a mapping between a mapped IP address and the service IP address.
12. The non-transitory computer readable medium of claim 11 , wherein a service provider application in a service provider network exchanges one or more messages with a service consumer application using the mapped IP address.
13. The non-transitory computer readable medium of claim 12 , wherein the mapped IP address is returned to the service provider application.
14. The non-transitory computer readable medium of claim 8 , wherein the service consumer network comprises a private cloud or network and a service provider network comprises a public cloud or network.
15. A computing system comprising:
a memory to hold a set of instructions;
a computer processor to execute the set of instructions, which when executed cause a set of acts comprising:
identifying a reverse connection endpoint (RCE) at a service consumer network;
initiating a connection with the service consumer network using the RCE;
trapping a redirection message from the service consumer network at a cloud networking infrastructure layer; and
configuring the cloud networking infrastructure layer to route corresponding communications to the service consumer network.
16. The computing system of claim 15 , wherein initiating the connection with the service consumer network using the RCE is in response to a request received from a service provider application in a service provider network.
17. The computing system of claim 15 , wherein the redirection message includes a service IP address in the service consumer network that is different from an IP address for the RCE.
18. The computing system of claim 17 , wherein configuring the cloud networking infrastructure layer to route corresponding communications to the service consumer network comprises at least updating a network address translation table to include a mapping between a mapped IP address and the service IP address.
19. The computing system of claim 18 , wherein a service provider application in a service provider network exchanges one or more messages with a service consumer application using the mapped IP address.
20. The computing system of claim 19 , wherein the mapped IP address is returned to the service provider application.
