assigning the deploying of the data to the primary storage of the second data center to the first portion of tasks;

assigning the configuring of the second data center with the second instance of the virtualized overlay network and the second instance of the group of virtualized volume identifiers to the second portion of tasks;

performing the first portion of tasks before determining to restore the first data center to the second data center; and

performing the second portion of tasks in response to determining to restore the first data center to the second data center.

2. The system of claim 1 , wherein the dividing of the tasks into the first portion of tasks and the second portion of tasks comprises:

assigning the deploying of the data to the secondary storage of the second data center to the first portion of tasks.

3. The system of claim 1 , wherein the second data center comprises compute components, and wherein the operations further comprise:

powering on the compute components in response to determining to restore the first data center to the second data center.

4. The system of claim 3 , wherein a first charge is associated with maintaining the compute components as powered off, wherein a second charge is associated with maintaining the compute components as powered on, and wherein the first charge is less than the second charge.

5. The system of claim 1 , wherein the operations further comprise:

repeatedly populating the primary storage or the secondary storage with updated data from the first data center before determining to restore the first data center to the second data center.

6. The system of claim 1 , wherein the operations further comprise:

in response to determining to restore the first data center to the second data center, determining to provision a first amount of resources for the second data center that corresponds to a used amount of resources of the first data center, wherein the used amount of resources is less than an ordered amount of resources of the first data center.

7. A method, comprising:

maintaining, by a system comprising at least one processor, a first data center that 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, the first data center storing data comprising first instances of a group of virtualized workloads that operate on the first data center;

determining, by the system, a service level agreement associated with providing a second data center as a backup to the first data center;

based on the service level agreement, dividing, by the system, tasks into a first portion of tasks to complete before determining to restore the first data center to the second data center, and a second portion of tasks to perform after determining to restore the first data center and the second data center, wherein the tasks comprise,

deploying the data to a secondary storage of the second data center, wherein the deploying of the data to a secondary storage is assigned to the first portion of tasks,

deploying the data to a primary storage of the second data center, and

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 the configuring is assigned to the second portion of tasks;

performing the first portion of tasks before determining to restore the first data center to the second data center; and

performing the second portion of tasks in response to determining to restore the first data center to the second data center.

8. The method of claim 7 , wherein deploying the data to the storage of the second data center comprises:

deploying, by the system, the data to a primary storage of the second data center in response to determining to restore the first data center to the second data center.

9. The method of claim 7 , wherein the operations further comprise:

in response to determining that a configuration of the first data center has changed, updating, by the system, the configuring of the second data center.

10. The method of claim 7 , wherein the operations further comprise:

in response to determining that a first amount of resources deployed at the first data center has changed by a first amount, changing, by the system, a second amount of resources deployed at the second data center by a second amount that corresponds to the first amount.

11. The method of claim 7 , further comprising:

activating, by the system, the second instance of the virtualized overlay network and the second instance of the group of virtualized volume identifiers in response to determining to restore the first data center to the second data center.

12. The method of claim 11 , wherein a first charge is associated with maintaining the second instance of the virtualized overlay network and the second instance of the group of virtualized volume identifiers as inactive, wherein a second charge is associated with maintaining the second instance of the virtualized overlay network and the second instance of the group of virtualized volume identifiers as active, wherein the first charge is less than the second charge, and wherein a cost value of a cost data structure is determined as a function of a first measure of inactivity of the second instance of the virtualized overlay network and the second instance of the group of virtualized volume identifiers, and a second measure of activity of the second instance of the virtualized overlay network and the second instance of the group of virtualized volume identifiers.

13. The method of claim 7 , wherein the service level agreement indicates a recovery time objective of restoring the first data center to the second data center.

14. A non-transitory computer-readable medium comprising instructions that, in response to execution, cause a system comprising at least one processor to perform operations, comprising:

determining a service level agreement associated with providing a second data center as a backup to a first data center, wherein the first data center comprises a first instance of a virtualized overlay and a first instance of a group of virtualized volume identifiers that abstract physical storage volumes;

based on the service level agreement, dividing, by the system, tasks into a first portion of tasks to complete before determining to restore the first data center to the second data center, and a second portion of tasks to perform after determining to restore the first data center and the second data center, wherein the dividing comprises,

assigning deploying the data to a secondary storage of the second data center to the first portion of tasks, and

assigning 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 to the second portion of tasks;
