Multi-tenant environment with overlapping address space

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computing device to cause the computing device to:

• receive a communication from a first tenant of a multi-tenant computing environment over a first dedicated communication network, the communication being transmitted to a first globally unique internet protocol (IP) address in a first dedicated environment in a service provider environment, the first dedicated environment being dedicated to the first tenant;
• receive a communication from a second tenant of the multi-tenant computing environment over a second dedicated communication network, the communication from the second tenant being transmitted to the first globally unique IP address in a second dedicated environment in the service provider environment, the second dedicated environment being dedicated to the second tenant;
• network address translate the first globally unique IP address, to which the communication from the first tenant was transmitted, to a first non-globally unique IP address that is locally unique in the service provider environment;
• network address translate the first globally unique IP address, to which the communication from the second tenant was transmitted, to a second non-globally unique IP address that is locally unique in the service provider environment;
• provide the communication from the first tenant access to a shared resource in the service provider environment using the first non-globally unique IP address;
• and
• provide the communication from the second tenant access to the shared resource using the second non-globally unique IP address.

A system comprising:

• a processor, a computer readable memory, and a computer readable storage medium;
• program instructions to receive a communication from a first tenant of a multi-tenant computing environment over a first dedicated communication network, the communication being transmitted to a first globally unique internet protocol (IP) address in a first dedicated environment in a service provider environment, the first dedicated environment being dedicated to the first tenant;
• program instructions to receive a communication from a second tenant of the multi-tenant computing environment over a second dedicated communication network, the communication from the second tenant being transmitted to the first globally unique IP address in a second dedicated environment in the service provider environment, the second dedicated environment being dedicated to the second tenant;
• program instructions to network address translate the first globally unique IP address, to which the communication from the first tenant was transmitted, to a first non-globally unique IP address that is locally unique in the service provider environment;
• program instructions to network address translate the first globally unique IP address, to which the communication from the second tenant was transmitted, to a second non-globally unique IP address that is locally unique in the service provider environment;
• program instructions to provide the communication from the first tenant access to a shared resource in the service provider environment using the first non-globally unique IP address;
• and
• program instructions to provide the communication from the second tenant access to the shared resource using the second non-globally unique IP address,
• wherein the program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory.
