Abstract

A system can maintain a first data center that comprises a virtualized overlay network and virtualized volume identifiers. The system can determine to perform a restore of data of the first data center to a second data center, the data comprising first instances of virtualized workloads. The system can transfer the data to the second data center. The system can configure the second data center with the virtualized overlay network and the virtualized volume identifiers. The system can operate the virtualized workloads on the second data center, the second instances of the virtualized workloads invoking the second instance of the virtualized overlay network and the second instance of the virtualized volume identifiers.

First claim

What is claimed is:

1. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
maintaining a first data center that comprises a first instance of a virtualized overlay network that virtualizes physical network resources and a first instance of a group of virtualized volume identifiers that virtualize a first group of physical storage volumes of the first data center;
determining to perform a restore of data of the first data center to a second data center, the data comprising first instances of a group of virtualized workloads that operate on the first data center;
transferring the data to the second data center;
based on the determining to perform the restore, configuring the second data center with a second instance of the virtualized overlay network and a second instance of the group of virtualized volume identifiers,
wherein configuring the second data center comprises associating respective virtualized volume identifiers of the group of virtualized volume identifiers from the first data center with respective second physical storage volumes of a second group of physical storage volumes of the second data center, and
wherein the configuring is performed based on information about the group of virtualized volume identifiers stored in a cloud platform that is separate from the first data center and the second data center; and

operating second instances of the group of virtualized workloads on the second data center, the second instances of the group of virtualized workloads invoking the second instance of the virtualized overlay network and the second instance of the group of virtualized volume identifiers.

2. The system of claim 1 , wherein the operations further comprise:
disconnecting the first data center from a public communications network before performing the operating of the second instances of the group of virtualized workloads on the second data center.

3. The system of claim 1 , wherein the first data center is part of a first availability zone and the second data center is part of a second availability zone, wherein a network of the first availability zone and the second availability zone comprises a stretched Layer 2 network that spans the first data center and the second data center, wherein a virtualization layer of the first availability zone and the second availability zone spans the first data center and the second data center, and wherein a high availability process utilizes a first orchestrator that is local to the first data center and a second orchestrator that is local to the second data center.

4. The system of claim 1 , wherein the first instance of the virtualized overlay network and the second instance of the virtualized overlay network present a same virtualized overlay network while referencing respective different underlying physical network resources.

5. The system of claim 1 , wherein the second data center comprises a group of compute components that lack local storage, and wherein the group of compute components boots from a group of separate physical storage volumes on which the data is stored and that are referenced by the second instance of the group of virtualized volume identifiers.

6. The system of claim 1 , wherein the cloud platform stores information about the first instance of the virtualized overlay network, and wherein the cloud platform utilizes the stored information about the first instance of the virtualized overlay network to configure the second data center.

7. The system of claim 1 , wherein the first instance of the group of virtualized volume identifiers and the second instance of the group of virtualized volume identifiers present a same virtualized group of storage volumes while referencing respective different underlying physical storage volumes.

8. A method, comprising:
determining, by a system comprising a processor, to transfer data of a first data center to a second data center, wherein the data comprises first instances of a group of virtualized workloads that operate on the first data center, and wherein the first data center comprises a first instance of a virtualized overlay network that abstracts physical network resources and a first instance of a group of virtualized volume identifiers that abstract physical storage volumes of the first data center;
transferring, by the system, the data to the second data center;
configuring, by the system, the second data center with a second instance of the virtualized overlay network and a second instance of the group of virtualized volume identifiers wherein configuring the second data center comprises associating respective virtualized volume identifiers of the group of virtualized volume identifiers from the first data center with respective second physical storage volumes of a second group of physical storage volumes of the second data center; and
operating, by the system, second instances of the group of virtualized workloads on the second data center, the second instances of the group of virtualized workloads invoking the second instance of the virtualized overlay network and the second instance of the group of virtualized volume identifiers.

9. The method of claim 8 , wherein the transferring of the data to the second data center comprises:
transferring the data from storage of a cloud platform to the second data center.

10. The method of claim 8 , wherein the transferring of the data to the second data center comprises:
transferring the data from storage of a cloud platform to a secondary storage of the second data center, and then to primary storage resources from which the virtualized workloads operate.

11. The method of claim 8 , wherein a first virtualized volume identifier of the virtualized volume identifiers references a first physical storage device of the first data center having a first physical identifier, wherein the first virtualized volume identifier references a second physical storage device of the second data center having a second physical identifier, and wherein the first physical identifier differs from the second physical identifier.

12. The method of claim 8 , wherein a first virtual network address of the virtualized overlay network references different physical network addresses on the first instance of the virtualized overlay network and on the second instance of the virtualized overlay network.

13. The method of claim 8 , wherein the data comprises virtualization management data that supports operation of the group of virtualized workloads.

14. The method of claim 8 , wherein the first instance of the group of virtualized volume identifiers that abstract physical storage volumes spoofs the physical storage volumes.

15. A non-transitory computer-readable medium comprising instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising: determining to transfer data of a first data center to a second data center, wherein the first data center comprises a first overlay network that presents an overlay and a first storage virtualization that presents virtual storage of first physical storage of the first data center; transferring the data to the second data center; configuring the second data center with a second overlay network that presents the overlay and a second storage virtualization that presents the virtual storage relative to second physical storage of the second data center, wherein configuring the second data center comprises associating respective virtualized volume identifiers of a group of vir
