Abstract

Embodiments relate to systems and methods for reclassifying a set of virtual machines in a cloud-based network. The systems and methods can analyze virtual machine data to determine performance metrics associated with the set of virtual machines, as well as target data to determine a set of target machines to which the set of virtual machines can be reassigned or reclassified. In embodiments, benefits of reassigning any of the set of virtual machines to any of the set of target virtual machines can be determined. Based on the benefits, the systems and methods can reassign or reclassify appropriate virtual machines to appropriate target virtual machines.

Claims

1. A method comprising:

analyzing, by a processor, program code of a first virtual machine to determine an operation of the first virtual machine during a first time period;

analyzing the operation of the first virtual machine;

simulating, in view of the operation of the first virtual machine during the first time period, an operation of the first virtual machine during a second time period that is subsequent to the first time period;

determining, in view of a simulation of the operation of the first virtual machine during the second time period, whether a resource of a target virtual machine supports a virtual machine configuration of the first virtual machine as simulated with respect to the second time period;

in view of a determination that the resources of a target virtual machine supports the virtual machine configuration of the first virtual machine as simulated with respect to the second time period,

terminating the first virtual machine,

instantiating the target virtual machine with the virtual machine configuration, and

migrating operations associated with the first virtual machine to the target virtual machine; and

in view of a determination that one or more resources of the target virtual machine do not support the virtual machine configuration of the first virtual machine as simulated with respect to the second time period, instantiating a new virtual machine with the virtual machine configuration.

2. The method of claim 1, further comprising:

reassigning the first virtual machine to the target virtual machine.

3. The method of claim 1, wherein the target virtual machine is in a cloud network.

4. The method of claim 1, further comprising:

generating a reassignment recommendation to reassign the first virtual machine to the target virtual machine; and

providing the reassignment recommendation to an administrator.

5. The method of claim 1, wherein the determining is further in view of a metric of the first virtual machine.

6. The method of claim 5, wherein the virtual machine configuration improves the metric.

7. A system comprising:

a memory; and

a processor, operatively coupled to the memory, to;

analyze program code of a first virtual machine to determine an operation of the first virtual machine during a first time period;

simulate, in view of the operation of the first virtual machine during the first time period, an operation of the first virtual machine during a second time period that is subsequent to the first time period;

determine, in view of a simulation of the operation of the first virtual machine during the second time period, whether a resource of a target virtual machine supports a virtual machine configuration of the first virtual machine as simulated with respect to the second time period, wherein the target virtual machine is in a cloud network;

in view of a determination that the resource of a target virtual machine supports the virtual machine configuration of the first virtual machine as simulated with respect to the second time period,

terminate the first virtual machine,

instantiate the target virtual machine with the virtual machine configuration, and

migrate operations associated with the first virtual machine to the target virtual machine; and

in view of a determination that one or more resources of the target virtual machine do not support the virtual machine configuration of the first virtual machine as simulated with respect to the second time period, instantiate a new virtual machine with the virtual machine configuration.

8. The system of claim 7, wherein the processor is further to analyze the operation of the first virtual machine.

9. The system of claim 7, wherein the processor is further to

reassign the first virtual machine to the target virtual machine.

generate a reassignment recommendation to reassign the first virtual machine to the target virtual machine; and

provide the reassignment recommendation to an administrator.

11. The system of claim 7, wherein to determine whether a resource of a target virtual machine supports a virtual machine configuration of the first virtual machine as simulated with respect to the second time period is further in view of a metric of the first virtual machine.

12. The system of claim 11, wherein the virtual machine configuration improves the metric.

13. A system comprising:

a memory; and

a processor, operatively coupled to the memory, to;

analyze program code of a first virtual machine to determine an operation of the first virtual machine during a first time period;

simulate, in view of the operation of the first virtual machine during the first time period, an operation of the first virtual machine during a second time period that is subsequent to the first time period;

determine, in view of a simulation of the operation of the first virtual machine during the second time period, whether a resource of a target virtual machine supports a virtual machine configuration of the first virtual machine as simulated with respect to the second time period;
