Hi
We must be able to use WMQ from Microsoft Azure PaaS and are looking for solutions. I have posted a PMR but also want feedback/thoughts/experiences from the community
In our current setup we have WMQ Servers deployed on a corporate network accessible from Internet with server connection channels using SSL so "normal" applications can use WMQ Client to connect/send/receive
messages.
With Microsoft Azure PaaS (Worker Role and Web Role) we cannot install WMQ Client as with the standard WMQ Client installation package.
Azure Service bus have capabilities to use AMQP but WMQ doesn't support that which is a pity.
Have you any experience with Azure PaaS and WMQ integrations?
Do you have any suggestions on solutions?
The application to be deployed in Azure can include DLLs to be used but to my knowledge WMQ doesn't support WMQ Client DLLs to be picked as files and included with the application.
- Is it even doable?
- Have you seen any instruction/documentation on it?
Regards
Joacim

Not being at all Azure-aware, what is the technical reason that WMQ cannot be installed please?

| Sorry for my ignorance, but there is no a .NET-based MQ client (without platform-dependent components), as it exists for Java? |

Jeff, it could be a good news for this Azure question, because they simple use this component without any installation error...  |

I have heard a guy making an installation by bundle the MSI package in the app. When they start the service it checks if WMQ Client is installed and if not it executes a silent install. SSL certificate locations etc are looked up in runtime.
So can be done but with tricks and likely not very robust.
Since services can be moved in the PaaS to provide high quality of service (availability, scalability etc) and that means the installation will execute several times (takes time and risk for failure).

Jeff; please enlighten me 
What component/libs are you thinking of?
To my knowledge there is no similar way as for Java (JMS libs/Resource adapter) but I would be very happy if I am wrong.

Look up the concept of a managed library in .NET. Be aware that there are some limitations to using a managed library...

Can I just check/ Is the problem that you are having that you would like to be able to bundle the "Websphere Classes for .NET" [1] with you Azure PaaS web worker but you cannot. Is that because [1] contains some native code that does not run on Azure.
I have not tried this myself. Have you tried to extract the libraries out of [1] and bundle them with your Azure App? (Not implying this would be supported just want to understand if you have tried it and found it not to work). My understanding (2nd hand) is that these classes are not pure DLR managed code but include some DLLs. Is that what is causing the problem?

Thanks. Yes, checked it out but unfortunately its limitation of not supporting SSL is an issue since we use that for all external WMQ connections (as mentioned in first post).
Potentially if we could have Azure configured with VPN to our internal WMQ, then maybe it can be an option.

It is so clumsy. Java implementation contains (almost) all the features so I don't really understand why .NET implemenation ignored SSL support. |

Hi Rob,
Yes, if we could extract the necessary files from WMQ Client and bundle them as part of the application that will be deployed on Azure as Web Role or Worker Role; that would probably do the trick. You mention support and yes that is essential for us as a large enterprise to run solutions supported by our vendors (e.g. IBM and MS). Then of course we don't have 100% supported solutions but we must avoid them as long as possible.
Therefore we have not tried this trick ...unless we get a confirmation/guidance from IBM. That's why I have posted a PMR but also wanted this thread to discuss the challenge (for other to learn from) and eventually get ideas for a solution that works and doesn't violate the support
Regards
Joacim
