Has anybody implemented RDQM HA in a Cloud infrastructure (like AWS)?
I suppose if your cloud infrastructure was just hosting VMs, it would be no different then straight up VMs. What would be the advantage?
I would think that if you want to implement MQ in the cloud, you would use the IBM Integration Pak and allow the infrastructure to manage keeping the container that hosts the Qmgr alive somewhere. |

If AWS isn't keeping the infrastructure you're paying for up, why are you paying them?

Sure AWS will reboot the VM somewhere else, so the thought of RDQM HA config on three nodes would provide faster HA take over (I suppose). The nodes could be on different zones for even more robustness. I would not think RDQM HA can be hosted across cloud regions. |

Thank you very much Morag. That is two years old but I'm sure it is still valid (I would hope on current versions).
Since then, IBM has been promoting the IBM Cloud Integration Pak on Red Hat OpenStack. The queue managers would be in containers and not on VMs. I would have to assume the Qmgr data would need to live on a persistent store so that if the container goes away and comes back, the Qmgr can be "attached" to it to resume. This is where I get a little blurry (how would that happen?).
Isn't the point of the cloud to abstract the hardware from the software? |

I would assume that once the storage has been reattached you would use addmqinf to redefine the queue manager to the "rehydrated" host.  _________________ MQ & Broker admin |

OK, maybe the container manager could be directed to run the MQ HA scripts to shutdown and start up the Qmgr. The scripts could be modified to either create (if the Qmgr does not exist on the storage) or add the Qmgr and then start it. I suppose you could also backup the Qmgr before starting it. |
