- Assignees: VMWARE, INC. (Palo Alto, CA, US)
- Claim: 1. A method of operating a virtual network for a particular entity over a set of two or more public cloud datacenters, the method comprising: defining a larger, first virtual network over a larger, first set of the public cloud datacenters; defining, for the particular entity, a smaller, second virtual network over a smaller, second set of the public cloud datacenters that does not include all the public cloud datacenters in the first set; using the second virtual network to forward a first set of data messages associated with external machines of the particular entity outside of any public cloud datacenters; and based on a detected condition, using the first virtual network to forward a second set of data messages associated with the external machines of the particular entity through at least part of the traversal of the second set of data messages through the public cloud datacenters.
- Claim: 2. The method of claim 1 , wherein the first virtual network is a shared virtual network used by multiple entities, while the second virtual network is a dedicated virtual network used by the particular entity.
- Claim: 3. The method of claim 1 , wherein defining the larger, first virtual network comprises deploying and configuring a first set of forwarding elements in the larger, first set of the public cloud datacenters; defining the smaller, second virtual network comprises deploying and configuring a second set of forwarding elements in the smaller, second set of the public cloud datacenters; using the second virtual network comprises using forwarding elements in the second set to forward the first set of data messages; using the first virtual network comprises using forwarding elements in the first set to forward the second set of data messages.
- Claim: 4. The method of claim 3 , wherein the forwarding elements in the first set of forwarding elements are shared forwarding elements that are used to forward data message flows for multiple entities, while the forwarding elements in the second set of forwarding elements are dedicated forwarding elements that are used to forward data message flows for the particular entity.
- Claim: 5. The method of claim 1 , wherein a first set of forwarding elements in the first set of public cloud datacenters implement the first virtual network and a second set of forwarding elements in the second set of public cloud datacenters implement the second virtual network, and the detected condition is congestion at a particular forwarding element used to implement the second virtual network.
- Claim: 6. The method of claim 5 further comprising collecting statistics regarding data message flows processed by the second set of forwarding elements; based on the collected statistics, determining that a particular forwarding element in the second set of forwarding elements is congested; wherein using the first virtual network comprises redirecting a set of the data message flows away from the particular forwarding element to a forwarding element in a first set of forwarding elements.
- Claim: 7. The method of claim 6 , wherein redirecting the set of the data message flows comprises configuring a load balancer to redirect the set of the data message flows away from the particular forwarding element to the forwarding element in a first set of forwarding elements.
- Claim: 8. The method of claim 7 , wherein configuring the load balancer comprises configuring the load balancer to redirect 1 out of N new data message flows away from the particular forwarding element, wherein N is an integer.
- Claim: 9. The method of claim 6 , wherein collecting statistics comprises: generating, at the forwarding elements, statistics regarding data message flows that the forwarding elements process; collecting, at a controller, the generated statistics from the forwarding elements.
- Claim: 10. The method of claim 1 further comprising before defining the second virtual network, receiving an identification of the second set of the public cloud datacenters from the entity as the set of public cloud datacenters over which the second virtual network should be defined.
- Claim: 11. The method of claim 1 , wherein the first virtual network is administered by a virtual network provider (VNP) that deploys multiple different virtual networks for multiple different entities of a plurality of public cloud datacenters.
- Claim: 12. The method of claim 11 , wherein the first virtual network is for the VNP to manage all a set of virtual networks deployed for a set of entities by the VNP.
- Claim: 13. The method of claim 1 further comprising defining first and second sets of paths through the first and second virtual networks based on first and second sets of path-defining criteria, wherein the first set of path defining criteria for the first virtual network is different than the second set of path defining criteria for the second virtual network.
- Claim: 14. The method of claim 1 further comprising deploying and configuring forwarding elements in a plurality of public cloud datacenters in order to define the first and second virtual networks, wherein at least one forwarding element for the first virtual network is deployed and configured in a public cloud in which a forwarding element for the second virtual network cannot be deployed.
- Claim: 15. The method of claim 1 further comprising: collecting statistics regarding the second set of data messages that are forwarded through the first virtual network; generating a bill, based on the collected statistics, for the particular entity to pay in order to account for the particular entity's usage of the first virtual network.
- Claim: 16. A system for operating a virtual network for a particular entity over a set of two or more public cloud datacenters, the system comprising: a first set of managed forwarding elements deployed in a first set of public cloud datacenters (PCDs) to define a first virtual network across the first PCD set; a second set of managed forwarding elements deployed in a second set of PCDs to define a second virtual network across the second PCD set, the second PCD set not including all PCDs in the first PCD set, the second virtual network used to forward a first set of data messages associated with external machines of the particular entity outside of the public cloud datacenters; and a set of servers to detect a condition and in response to use the first virtual network to forward a second set of data messages associated with at least one external machine of the particular entity for at least part of the second set of data messages' traversal through the PCDs.
- Claim: 17. The system of claim 16 , wherein the first virtual network is a shared virtual network used by multiple entities, while the second virtual network is a dedicated virtual network used by the particular entity.
- Claim: 18. The system of claim 16 , wherein the forwarding elements in the first set of forwarding elements are shared forwarding elements that are used to forward data message flows for multiple entities, while the forwarding elements in the second set of forwarding elements are dedicated forwarding elements that are used to forward data message flows for the particular entity.
- Claim: 19. The system of claim 16 , wherein the detected condition is congestion at a particular forwarding element used to implement the second virtual network.
- Claim: 20. The system of claim 16 , wherein the second set of the PCDs are identified by the entity as the set of PCDs over which the second virtual network should be defined.
