Abstract

A system, method, and computer program product are provided for upgrading software associated with an operational distributed, state-full system. In operation, an upgrade system identifies a software upgrade to perform to software associated with a distributed, state-full system. The upgrade system identifies a storage to allocate for performing the software upgrade. The upgrade system identifies one or more customer groups to utilize the software upgrade. The upgrade system identifies a temporary process failure group to utilize for real-time testing of the software upgrade, based on the identified one or more customer groups. The upgrade system removes responsibilities of event servers currently serving the one or more customer groups and moves the one or more customer groups to utilize the software upgrade operating on the temporary process failure group. Further, the upgrade system monitors operation of the software upgrade utilized by the one or more customer groups operating on the temporary process failure group to determine whether there are any issues associated with the software upgrade.

Claims

1. A method, comprising:

identifying, by an upgrade system, a software upgrade to perform to software associated with a distributed, state-full system;

identifying, by the upgrade system, a storage to allocate for performing the software upgrade;

identifying, by the upgrade system, one or more customer groups to utilize the software upgrade;

creating, by the upgrade system, a temporary process failure group comprised of a plurality of processes raised within the storage for use in real-time testing of the software upgrade, based on the identified one or more customer groups;

removing, by the upgrade system, responsibilities of event servers currently serving the one or more customer groups and moving the one or more customer groups to utilize the software upgrade operating on the temporary process failure group, by assigning the one or more customer groups to the plurality of processes in the temporary process failure group;

monitoring, by the upgrade system, operation of the software upgrade utilized by the one or more customer groups operating on the temporary process failure group to determine issues associated with the software upgrade; and

dismissing, by the upgrade system, the temporary process failure group once it is determined that there are not any issues associated with the software upgrade such that the software upgrade is fully implemented to the distributed, state-full system.

2. The method of claim 1, further comprising identifying, by the upgrade system, additional customer groups to utilize the software upgrade.

3. The method of claim 2, further comprising removing, by the upgrade system, responsibilities of event servers currently serving the additional customer groups and moving the additional customer groups to utilize the software upgrade.

4. The method of claim 1, wherein the storage to allocate for performing the software upgrade includes a portion of existing storage being utilized in association with the software associated with the distributed, state-full system.

5. The method of claim 1, wherein the storage to allocate for performing the software upgrade includes new storage.

6. The method of claim 1, wherein a state and context of the one or more customer groups are stored as part of the processing environment of the temporary process failure group.

7. The method of claim 6, wherein when monitoring of the operation of the software upgrade indicates a failure of the software upgrade, rolling back the one or more customer groups to use of the event servers, wherein the rolling back is performed from a persistent layer using a current state.

8. The method of claim 1, wherein upon failure of one of the processes in the process failure group, a failover process is chosen by the upgrade system from the temporary process failure group.

9. A computer program product embodied on a non-transitory computer readable medium, comprising computer code for:

identifying, by an upgrade system, a software upgrade to perform to software associated with a distributed, state-full system;

identifying, by the upgrade system, a storage to allocate for performing the software upgrade;

identifying, by the upgrade system, one or more customer groups to utilize the software upgrade;

creating, by the upgrade system, a temporary process failure group comprised of a plurality of processes raised within the storage for use in real-time testing of the software upgrade, based on the identified one or more customer groups;

removing, by the upgrade system, responsibilities of event servers currently serving the one or more customer groups and moving the one or more customer groups to utilize the software upgrade operating on the temporary process failure group, by assigning the one or more customer groups to the plurality of processes in the temporary process failure group;

monitoring, by the upgrade system, operation of the software upgrade utilized by the one or more customer groups operating on the temporary process failure group to determine whether there are any issues associated with the software upgrade; and

dismissing, by the upgrade system, the temporary process failure group once it is determined that there are not any issues associated with the software upgrade such that the software upgrade is fully implemented to the distributed, state-full system.

10. The computer program product of claim 9, further comprising computer code for identifying, by the upgrade system, additional customer groups to utilize the software upgrade.

11. The computer program product of claim 10, further comprising computer code for removing, by the upgrade system, responsibilities of event servers currently serving the additional customer groups and moving the additional customer groups to utilize the software upgrade.

12. The computer program product of claim 9, wherein the storage to allocate for performing the software upgrade includes a portion of existing storage being utilized in association with the software associated with the distributed, state-full system.

13. The computer program product of claim 9, wherein the storage to allocate for performing the software upgrade includes new storage.

14. An upgrade system for implementing a method comprising:

identifying, by the upgrade system, a software upgrade to perform to software associated with a distributed, state-full system;

identifying, by the upgrade system, a storage to allocate for performing the software upgrade;

identifying, by the upgrade system, one or more customer groups to utilize the software upgrade;

creating, by the upgrade system, a temporary process failure group comprised of a plurality of processes raised within the storage for use in real-time testing of the software upgrade, based on the identified one or more customer groups;

removing, by the upgrade system, responsibilities of event servers currently serving the one or more customer groups and moving the one or more customer groups to utilize the software upgrade operating on the temporary process failure group, by assigning the one or more customer groups to the plurality of processes in the temporary process failure group;

monitoring, by the upgrade system, operation of the software upgrade utilized by the one or more customer groups operating on the temporary process failure group to determine whether there are any issues associated with the software upgrade; and

dismissing, by the upgrade system, the temporary process failure group once it is determined that there are not any issues associated with the software upgrade such that the software upgrade is fully implemented to the distributed, state-full system.

15. The upgrade system of claim 14, further comprising identifying, by the upgrade system, additional customer groups to utilize the software upgrade.

16. The upgrade system of claim 15, further comprising removing, by the upgrade system, responsibilities of event servers currently serving the additional customer groups and moving the additional customer groups to utilize the software upgrade.

17. The upgrade system of claim 14, wherein the storage to allocate for performing the software upgrade includes a portion of existing storage being utilized in association with the software associated with the distributed, state-full system.
