Abstract

A method for dynamic allocating of a resource capacity in a cloud computing deployment is disclosed. According to the method, a resource capacity allocation of a network instance is determined and a resource capacity demand of the network instance is monitored. If the resource capacity demand exceeds a first threshold value, the resource capacity allocation of the network instance is increased by allocating additional resource capacity of a shared pool of network instances. However, if the resource capacity demand falls below a second threshold value, the resource capacity allocation of the network instance is decreased by deallocating the additional resource capacity back to the shared pool of network instances.

Claims

1. A method for dynamic allocating of a resource capacity in a cloud computing deployment, the method comprising:

determining a resource capacity allocation of a network instance;

monitoring a resource capacity demand of the network instance;

if the resource capacity demand exceeds a first threshold value, increasing the resource capacity allocation of the network instance by allocating additional resource capacity of a shared pool of network instances; and

if the resource capacity demand falls below a second threshold value, decreasing the resource capacity allocation of the network instance by deallocating the additional resource capacity back to the shared pool of network instances.

2. The method of claim 1, further comprising:

receiving an allocation request from the network instance generated during a pre-boot operation of the network instance; and

providing initial resource capacity allocation of the network instance by allocating initial resource capacity of the shared pool of network instances.

3. The method of claim 1, wherein the monitoring of the resource capacity demand of the network instance is performed by the network instance;

and

wherein the increasing or decreasing of the resource capacity allocation of the network instance is performed by a controller of the shared pool.

4. The method of claim 1, wherein the monitoring of the resource capacity demand of the network instance is performed by a controller of the shared pool;

and

wherein the increasing or decreasing of the resource capacity allocation of the network instance is performed by the controller of the shared pool.

5. The method of claim 1, wherein the shared pool of network instances includes at least a first set of network instances deployed at a first site, a second set of network instances deployed at a second site, and a third set of network instances deployed at a third site.

6. The method of claim 5, wherein each of the first site, the second site, and the third site have the same or substantially same resource capacity.

7. The method of claim 1, wherein the resource capacity demand of the network instance is monitored by measuring an incoming data traffic to the network instance.

8. The method of claim 1, wherein the resource capacity allocation is increased or decreased based on dynamic control.

9. The method of claim 1, further comprising:

creating the shared pool of network instances by generating a plurality of tokens, wherein the tokens reside at the network instances of the shared pool.

10. The method of claim 9, wherein each of the tokens indicates an association of the network instance to the shared pool of network instances.

11. The method of claim 9, wherein the shared pool of network instances is created during a pre-boot time of the network instances.

12. A system for dynamic allocating of a resource capacity in a cloud computing deployment, the system comprising at least one processor and at least one memory storing processor-executable codes, wherein the at least one processor is configured to implement the following operations upon executing the processor-executable codes:

determining a resource capacity allocation of a network instance;

monitoring a resource capacity demand of the network instance;

if the resource capacity demand exceeds a first threshold value, increasing the resource capacity allocation of the network instance by allocating additional resource capacity of a shared pool of network instances; and

if the resource capacity demand falls below a second threshold value, decreasing the resource capacity allocation of the network instance by deallocating the additional resource capacity back to the shared pool of network instances.

13. The system of claim 12, further comprising a controller of the shared pool, the controller being configured to:

receive an allocation request from the network instance generated during a pre-boot operation of the network instance; and

provide initial resource capacity allocation of the network instance by allocating initial resource capacity of the shared pool of network instances.

14. The system of claim 12, wherein the shared pool of network instances includes at least a first set of network instances deployed at a first site, a second set of network instances deployed at a second site, and a third set of network instances deployed at a third site.

15. The system of claim 14, wherein each of the first site, the second site, and the third site have the same or substantially same resource capacity.

16. The system of claim 12, wherein the resource capacity demand of the network instance is monitored by measuring an incoming data traffic to the network instance.

17. The system of claim 12, wherein the resource capacity allocation is increased or decreased based on dynamic control.

18. The system of claim 12, wherein each of the network instances includes a token indicating an association of the network instance with the shared pool of network instances.

19. The system of claim 12, wherein the shared pool of network instances is created during a pre-boot time of the network instances.

20. A non-transitory processor-readable medium having instructions stored thereon, which when executed by one or more processors, cause the one or more processors to implement a method for dynamic allocating of a resource capacity in a cloud computing deployment, the method comprising:

determining a resource capacity allocation of a network instance;

monitoring a resource capacity demand of the network instance;

if the resource capacity demand exceeds a first threshold value, increasing the resource capacity allocation of the network instance by allocating additional resource capacity of a shared pool of network instances; and

if the resource capacity demand falls below a second threshold value, decreasing the resource capacity allocation of the network instance by deallocating the additional resource capacity back to the shared pool of network instances.
