Method and apparatus for rapid disaster recovery preparation in a cloud network
Various embodiments provide a method and apparatus of providing a rapid disaster recovery preparation in cloud networks that proactively detects disaster events and rapidly allocates cloud resources. Rapid disaster recovery preparation may shorten the recovery time objective (RTO) by proactively growing capacity on the recovery application(s)/resource(s) before the surge of recovery traffic hits the recovery application(s)/resource(s). Furthermore, rapid disaster recovery preparation may shorten RTO by growing capacity more rapidly than during “normal operation” where the capacity is increased by modest growth after the load has exceeded a utilization threshold for a period of time.
1. An apparatus for providing rapid disaster recovery preparation, the apparatus comprising:
a data storage; and
a processor communicatively coupled to the data storage, the processor being configured to:
monitor network metrics from a first network resource;

wherein the monitored network metrics comprise exogenous sensor information.
2. The apparatus of claim 1 , wherein the monitored network metrics comprise a monitored traffic flow, the monitored traffic flow comprising one or more traffic flow values.
3. The apparatus of claim 2 , wherein the determination that a disaster condition has occurred is based on a detection that the monitored traffic flow has been interrupted.
4. The apparatus of claim 2 , wherein the determination that a disaster condition has occurred is based on a detection that the monitored traffic flow has abnormal traffic patterns.
5. The apparatus of claim 1 , wherein the determination that a disaster condition has occurred is based on a confidence level.
6. The apparatus of claim 1 , wherein the determination that a disaster condition has occurred comprises further configuring the processor to:
determine a disaster severity level.
7. The apparatus of claim 1 , wherein the processor is further configured to:
analyze a plurality of network resources;
determine a disaster recovery recommendation based on the plurality of network resources; and
select the third network resource based on the disaster recovery recommendation.
8. The apparatus of claim 7 , wherein the processor is further configured to:
select the third network resource based on the disaster recovery recommendation.
9. The apparatus of claim 7 , wherein the processor is further configured to:
create the disaster warning alert message based on the disaster recovery recommendation.
10. An apparatus for providing rapid disaster recovery preparation, the apparatus comprising:
a data storage; and
a processor communicatively coupled to the data storage, the processor being configured to:
receive a disaster warning alert message; and
perform a rapid elastic growth operation, the rapid elastic growth operation comprising: a growth of network resource prior to exceeding a utilization threshold;
wherein the rapid elastic growth operation further comprises a growth rate that is greater than twice a normal growth rate of resource allocated when the utilization threshold is exceeded.
11. The apparatus of claim 10 , wherein the rapid elastic growth operation further comprises a growth rate based on the received disaster warning alert message.
12. The apparatus of claim 10 , wherein the processor is further configured to:
monitor a traffic load;
determine that a disaster condition does not exist based on the monitored traffic load; and
in response to the determination that the disaster condition does not exist, perform an elastic shrinkage operation, the elastic shrinkage operation releasing at least a portion of the growth of network resources.
13. A recovery system for providing rapid disaster recovery preparation, the system comprising:
at least one network resource;
a plurality of data centers, the plurality of data centers comprising a disaster-impacted data center and a recovery data center;
a resource monitor apparatus communicatively coupled to the at least one network resource and the plurality of data centers, the resource monitor apparatus being configured to:
receive network metrics from the at least one network resource;
determine that a disaster condition has occurred that potentially impacts availability of the disaster-impacted data center, the determination being based on the received network metrics; and
send a disaster warning alert message to the recovery data center; and
the recovery data center being configured to:
receive the disaster warning alert message; and
perform a rapid elastic growth operation, the rapid elastic growth operation comprising: a growth of network resource prior to exceeding a utilization threshold;
wherein the rapid elastic growth operation further comprises a growth rate that is greater than twice a normal growth rate of resource allocated when the utilization threshold is exceeded.

determining, by the processor in cooperation with the data storage, that a disaster condition has occurred that impacts availability of a second network resource based on the received network metrics; and
sending, by the processor in cooperation with the data storage, a disaster warning alert message to a third network resource;
wherein the first, second and third network resources are different resources; and
wherein the network metrics comprise exogenous sensor information.
16. The method of claim 15 , wherein the received network metrics comprise a monitored traffic flow, the monitored traffic flow comprising one or more traffic flow values.
