Abstract

Some demonstrative embodiments of the invention include, for example, devices, systems and methods of operating one or more virtual logical sites. A method may include, for example, running on a server at least one first virtual machine implementing at least part of a first virtual logical site, and at least one second virtual machine implementing at least part of a second virtual logical site interchangeable with the first virtual logical site. Other embodiments are described and claimed.

Claims

1. A computing system comprising:

one or more servers to run at least first and second interchangeable virtual logical sites,

wherein a server of said one or more servers is to run at least one first virtual machine implementing at least part of said first virtual logical site and at least one second virtual machine implementing at least part of said second virtual logical site.

2. The computing system of claim 1, wherein said first and second virtual machines are interchangeable.

3. The computing system of claim 1, wherein said first virtual machine is a substantial clone of said second virtual machine.

4. The computing system of claim 1, wherein said first virtual machine implements a service of a type different than a service type implemented by said second virtual machine.

5. The computing system f claim 1, wherein said first and second virtual logical sites are substantial clones.

6. The computing system of claim 1 comprising at least one virtualization manager to allocate one or more physical resources of said server between said first and second virtual machines based on a traffic load of traffic intended for said first and second virtual logical sites.

7. The computing system of claim 1, comprising at least one synchronization manager to synchronize between corresponding virtual machines of said first and second virtual logical sites.

8. The computing system of claim 1, wherein when a change-over operation is to be performed said one or more servers are to:

route production traffic to said second virtual logical site;

modify said first virtual logical site to generate a modified first virtual logical site; and

route said production traffic to said modified first virtual logical site and to said second virtual logical site.

9. The computing system of claim 8, wherein said one or more servers are to operate said modified first virtual logical site in a testing environment.

10. The computing system of claim 8, wherein said server is to allocate one or more physical resources of said server between said first and second virtual machines during said change over operation.

11. The computing system of claim 8, wherein said one or more servers are to:

route said production traffic to said modified first virtual logical site;

modify said second virtual logical site to generate a modified second virtual logical site; and

route said production traffic to said modified first and second virtual logical sites.

12. The computing system of claim 1, wherein said at least one first virtual machine comprises a plurality of first virtual machines implementing a first plurality of services of said first virtual logical site, and

wherein said at least one second virtual machine comprises a plurality of second virtual machines implementing a second plurality of services of said second virtual logical site.

13. The computing system of claim 1 comprising a dispatcher to dispatch traffic to said first and second virtual logical sites via a single entry point.

14. A method comprising:

running on a server at least one first virtual machine implementing at least part of a first virtual logical site, and at least one second virtual machine implementing at least part of a second virtual logical site interchangeable with said first virtual logical site.

15. The method of claim 14, wherein said first and second virtual machines are interchangeable.

16. The method of claim 14, wherein said first virtual machine is a substantial clone of said second virtual machine.

17. The method of claim 14, wherein said first and second virtual logical sites are substantial clones.

18. The method of claim 14 comprising running said first and second virtual logical sites on a set of one or more servers including said server.

19. The method of claim 14 comprising allocating one or more physical resources of said server between said first and second virtual machines based on a traffic load of traffic intended for said first and second virtual logical sites.

20. The method of claim 14 comprising synchronizing between said first and second virtual logical sites.

21. The method of claim 14 comprising performing a change-over operation including:

routing production traffic to said second virtual logical site;

modifying said first virtual logical site to generate a modified first virtual logical site; and

routing said production traffic to said modified first virtual logical site and said second virtual logical site.

22. The method of claim 21 comprising allocating one or more physical resources of said server between said first and second virtual machines during said change over operation.

23. The method of claim 21 comprising:

routing said production traffic to said modified first virtual logical site;

modifying said second virtual logical site to generate a modified second virtual logical site; and

routing said production traffic back to said modified first and second virtual logical sites.

24. The method of claim 21 comprising operating said modified first virtual logical site in a testing environment.

25. The method of claim 14, wherein running said at least one first virtual machine comprises running on said server a plurality of first virtual machines implementing a first plurality of services of said first virtual logical site, and

wherein running said at least one second virtual machine comprises running on said server a plurality of second virtual machines implementing a second plurality of services of said second virtual logical site.

26. A server to run at least one first virtual machine implementing at least part of a first virtual logical site and at least one second virtual machine implementing at least part of a second virtual logical site interchangeable with said first virtual logical site.

27. The server of claim 26, wherein said first and second virtual machines are interchangeable.

28. The server of claim 26, wherein said first virtual machine is a substantial clone of said second virtual machine.

29. The server of claim 26, wherein said first and second virtual machines implement at least one different service.

30. The server of claim 26, wherein when a change-over operation is to be performed said server is to modify said first virtual machine.

31. The server of claim 30, wherein said server is to allocate one or more physical resources of said server between said first and second virtual machines during said change over operation.

32. The server of claim 26, wherein said at least one first virtual machine comprises a plurality of first virtual machines implementing a first plurality of services of said first virtual logical site, and

wherein said at least one second virtual machine comprises a plurality of second virtual machines implementing a second plurality of services of said second virtual logical site.

33. A computer program product comprising a computer-useable medium including a computer-readable program, wherein the computer-readable program when executed on at least one computer causes the computer to:

run at least one first virtual machine implementing at least part of a first virtual logical site, and at least one second virtual machine implementing at least part of a second virtual logical site interchangeable with said first virtual logical site.

34. The computer program product of claim 33, wherein said computer-readable program causes said at least one computer to allocate one or more physical resources of said computer between said first and second virtual machines based on a traffic load of traffic intended for said first and second virtual logical sites.

35. The computer program product of claim 33, wherein said computer-readable program causes said at least one computer to perform a change-over operation including:
