Abstract
A method and a device for duplicating a data center having an original public address space and an original private address space are proposed. The method comprises the steps of copying the data center for providing at least two copied data centers; to each of the copied data centers, allocating a new public address space and the original private address space of the data center; and providing an address translation component which is configured to re-address traffic such that traffic directed to an address of the original public address space is directed to a corresponding address of one of the new public address spaces of the copied data centers.

A method for duplicating a data center (1) having an original public address space and an original private address space, the method comprising:
- copying (201) the data center (1) for providing at least two copied data centers (11, 12),
- to each of the copied data centers (11, 12), allocating (202) a new public address space and the original private address space of the data center (1), and
- providing (203) an address translation component (40) which is configured to re-address traffic such that traffic directed to an address of the original public address space is directed to a corresponding address of one of the new public address spaces of the copied data centers (11, 12).
A device (70) for duplicating a data center (1) having an original public address space and an original private address space, the device (70) comprising:
- a copying entity (71) which is configured to copy the data center (1) such that at least two copied data centers (11, 12) are provided,
- an allocating entity (72) which is configured to allocate, to each of the copied data centers (11, 12), a new public address space and the original private address space of the data center (1), and
- a providing entity (73) for providing an address translation component (40) which is configured to re-address traffic such that traffic directed to an address of the original public address space is directed to a corresponding address of one of the new public address spaces of the copied data centers (11, 12).
A system (50) for substituting a data center (1) having an original public address space and an original private address space, the system (50) comprising:
- at least two copied data centers (11, 12), wherein each of the copied data centers (11, 12) has a new public address space and the original private address space of the data center (1), and
- an address translation component (40) which is configured to re-address traffic such that traffic directed to an address of the original public address space is directed to a corresponding address of one of the new public address spaces of the copied data centers (11, 12).
