Abstract

The present disclosure is directed to systems and method for providing a virtual appliance. One or more application delivery controller appliances intermediary to a plurality of clients and a plurality of servers perform a plurality of application delivery control functions on network traffic communicated between the plurality of clients and the plurality of servers. A virtual application delivery controller is deployed on a device intermediary to the plurality of clients and the plurality of servers. The virtual application delivery controller executing on the device performs one or more of the plurality of application delivery control functions on network traffic communicated between the plurality of clients and the plurality of servers.

Claims

1. A method for deploying a virtual application delivery controller, the method comprising:

(a) performing, by one or more application delivery controller appliances intermediary to a plurality of clients and a plurality of servers, a plurality of application delivery control functions on network traffic communicated between the plurality of clients and the plurality of servers;

(b) deploying a virtual application delivery controller on a device intermediary to the plurality of clients and the plurality of servers; and

(c) performing, by the virtual application delivery controller executing on the device, one or more of the plurality of application delivery control functions on network traffic communicated between the plurality of clients and the plurality of servers.

2. The method of claim 1, wherein step (b) further comprises deploying the virtual application delivery controller in a virtualized environment provided by the device.

3. The method of claim 1, wherein step (b) further comprises deploying the virtual application delivery controller to execute on a virtual machine provided by the device.

4. The method of claim 1, wherein step (b) further comprises deploying the virtual application delivery controller to execute as a virtual machine on the device.

5. The method of claim 1, wherein step (b) further comprises requesting a cloud service to execute the virtual application delivery controller on resources provided by the cloud service.

6. The method of claim 1, wherein step (b) further comprises installing the virtual application delivery controller to execute in a non-virtualized environment of the device.

7. The method of claim 1, wherein step (b) further comprises determining, by a centralized command center to deploy the virtual application delivery controller.

8. The method of claim 1, wherein step (b) further comprises configuring for deployment the one or more of the plurality of application delivery control functions for the virtual application delivery controller.

9. The method of claim 1, wherein step (c) further comprises performing, by the virtual application delivery controller, the one or more of the plurality of application delivery control functions on a first portion of network traffic concurrently to the one or more application delivery controller appliances performing the plurality of application delivery control functions on a second portion of network traffic.

10. The method of claim 1, wherein step (c) further comprises performing, by the virtual application delivery controller, a first application delivery control function on a first portion of network traffic subsequent to an application delivery controller appliance performing a second application delivery control function on the first portion of network traffic.

11. A method for managing a plurality of application delivery controllers of an application delivery network, the method comprising:

(a) monitoring, by an application delivery fabric (ADF) manager executing on a device, an application delivery fabric (ADF) network comprising a deployment of a plurality of application delivery controllers intermediary to a plurality of a clients and a plurality of servers;

(b) determining, by the ADF manager responsive to monitoring, that an operational or performance characteristic of the ADF network fails a corresponding threshold; and

(c) dynamically deploying, by the ADF manager responsive to the determination, a virtual application delivery controller as part of the ADF network.

12. The method of claim 11, wherein step (a) further comprises establishing, by the ADF manager, one or more application delivery controller appliances as part of the ADF network.

13. The method of claim 11, wherein step (a) further comprises establishing, by the ADF manager, one or more virtual application delivery controllers as part of the ADF network.

14. The method of claim 11, wherein step (b) further comprises determining, by the ADF manager responsive to monitoring, that a number of users of the plurality of application delivery controllers exceeds a threshold.

15. The method of claim 11, wherein step (b) further comprises determining, by the ADF manager responsive to monitoring, that a number of connections of the plurality of application delivery controllers exceeds a threshold.

16. The method of claim 11, wherein step (b) further comprises determining, by the ADF manager responsive to monitoring, that response times of servers via the plurality of application delivery controllers exceeds a threshold.

17. The method of claim 11, wherein step (b) further comprises determining, by the ADF manager responsive to monitoring, that one of a bandwidth or transmission rates via the plurality of application delivery controllers exceeds a threshold.

18. The method of claim 11, wherein step (c) further comprises dynamically deploying the virtual application delivery controller via a cloud service.

19. The method of claim 11, further comprising undeploying a virtual application delivery controller from the ADF network responsive to monitoring.
