Hi,
The VM from my blog is a bit outdated, but it contains a guide how you can integrate Virgo (and other projects) into CF. What you get currently is support for all Virgo artifacts and auto-staging of Spring modules and the ability to update Virgo's version.
I think Virgo's integration in CF can be used for productive application. The question here is what do you need from the infrastructure (IaaS), the platform (PaaS) or do you want to build a cloud based software solution (SaaS).
To be productive in my opinion you need to have provisioning of VMs that can be turned into DEA nodes and perhaps elasticity (scale-in/out) in case your application supports multiple instances.
The provisioning as you may know was not part of CF offering, although the now BOSH solves part of the problem. Another part however is to find a hosting infrastructure (Amazon, OpenStack, OpenShift, Cloud Foundry, RackSpace....) or to build a cloud yourself.
If you don't need these IaaS features than you can probably live with several VMs hosing Virgo instances.
Since Virgo is not supported by cloudfoundry.com or other CF based hostings, so you'll have to host it yourself. You can use your own hardware or existing IaaS to build CF based PaaS.
Regards,
Hristo Iliev

Hi
I have to confess that I haven't deployed a Virgo app on Cloud Foundry myself yet, but you might want to take a look at the recent support we added for "standalone" apps, which essentially lets you deploy any JVM, Ruby, Node etc app and specify startup/run commands and variables. AIUI Virgo can launch from the command line so this should work, assuming you add the correct JAVA_OPTIONS in the manifest.yml file.
There's a great blog post detailing this new support.
See "Cloud Foundry improves support for background processing" on our blog at cloudfoundry.com
Do let us know if you have any further questions. We have an IRC channel on freenode #cloudfoundry and often respond to that hashtag on Twitter, too.

Hi,
Great work here! I am new to Cloud Foundary, but have spent some time on Virgo. From the discussions above, it looks like there are two options to get Virgo working in Cloud Foundry:
- Use the Virgo integration done by Hristo Iliev.
- Run Virgo as a standalone app, as in Andy's email.
I haven't tried these options, but any comments on my questions below would be appreciated very much. Assuming I have 2 apps A & B to run in Virgo, with A consuming the OSGi services published by B.
- If using option #1, would the OSGi service published by B still work for A? If I scale A to have 10 instance and B still has 1 instance, how could they pair up?
- If using option #2, I believe app A & B and the OSGi services will work. But will I lose the capability of deploying new app (such as through the Virgo admin console) to a running instance of Virgo, since it apparently conflicts with the way vmc update an app (which is Virgo plus all apps in it)? If it still works for 1 instance, how about if I scale up the instances of Virgo to 10?
Best Wishes,
Ruoyun

Hi Ruoyun,
If you want to scale your application to more than one VM/instance/process then its best to provide remote API (REST, JMX, remote OSGi services). I personally recommend REST as a way to achieve statefulness. Remote API is needed to scale your applications and to enable features like discovery, failover, etc.
Both options (#1 and #2) will case update not only to your application but Virgo as well, so there is no real difference there. However since option #2 is better suited for application servers I would recommend to go in this direction.
As for OSGi services - they are not much different than what ordinary (one instance/VM/process) Virgo provides. The cloud case enables you to have more than one instance/VM/process, hence my recommendation to have remote API.
Regards,
Hristo Iliev

Hi, Hristo Iliev,
Thank you very much for the quick response. Looks like OSGi make things harder if I want to scale the deployment of a single app (run many instances of it).
Currently I have quite a number of apps running on Virgo, and new apps could be developed and added to a running Virgo server. I will give a try on option #2, which is basically scaling at app server level (run many instances of Virgo). My concern, however, is I probably can't add a new app directly to a Virgo instance running on the Cloud, as the other instances would be out of sync. I have to deploy new app locally to a local Virgo, then push the whole stack (Virgo plus all apps deployed within it) to cloud. Does it make senses?
Best Wishes,
Ruoyun

It seems you just need to provide your local Virgo instance and push it together with your application.
