The videos of all the OW2Con2011 have been published to the OW2 Youtube channel. My talk about Petals BPM and The Cloud is also available.
You are right, I need to smile more, be less tired and have a demo of the BPM editor working on low resolution displays… BTW, the demo of the DSB Monitoring & Management console used to deploy and monitor BPEL process works.

I was in Paris last week for the OW2 annual conference and I gave a talk called “Petals BPM and the Cloud” during the Open Cloud Summit Session (wow what a name!). This talk was about showing that we have things running and ready to be published in the Cloud. As I said during my talk, difficulty is not to provide the SaaS layer, pushing a Web app to the Cloud is not so hard (and not so interesting). The interesting part is about building the PaaS layer. In the current case, the PaaS will provide “Integration as a Service”, or how we can use Petals Service Bus, to provide ways to integrate, orchestrate, manage and monitoring business services.
My son is an open source fan
So let’s go back on my talk, where I planned to show things working… Unfortunately, I was not able to show anything due to some low resolution problems and this was really a shame; next time I will prepare a video in case of something like that happens. I am going to record these videos this week to show that we have interesting things under development : We can create business processes with Petals BPM and deploy them on the service bus in order to execute and monitor the process itself in a distributed way.
While waiting these videos, here are the slides of my talk. There are sort of ‘zen’ slides so the talk I gave was really important to understand all… So come and see me next time, or just send me comments.
For the other parts of the conference, as usual, there were really interesting presentations and discussions around OW2, open source and Cloud. One fun thing which I learnt was that OW2-Jonas is used in MS Azure Cloud solution as support of J2EE apps (can I also inform that Microsoft was a big sponsor of OW2Con? Yes, really, they gave money for an open source conference, that’s fun). Well, there were so many interesting things and I can not list all here. But open source is really something companies should have a look if they do not did it already, they will be surprised to see how active and professional is the community behind it.

This year again, I submitted a talk proposal to the OW2 annual conference and it has just been approved by the OW2 management office.
While last year I spoke about some conceptual things around the Distributed Service Bus and the Cloud, this year I will go one step further with some live demonstrations not only dealing with service bus stuff, but also with some BPM tools and the Cloud stack we actively develop in the research team at PetalsLink. Here is my talk proposal:
All the services are moving to the Cloud, so are business processes. In this talk, we will show how to create collaborative business processes using an open source SaaS BPMN Editor. But designing business processes is not enough, why not running them in the Cloud? We will see that we can rely on a completely Cloud-aware SOA software infrastructure combining several open sources solutions such as a Service Bus and IaaS framework. The resulting ‘Cloud Service Bus’ allows the integration of in-house services in order to benefit from Cloud-based features such as elasticity, load balancing, service clustering and migration. This Cloud Service Bus will serve as the runtime basis of the business processes producing a Petals Cloud Stack solution. All in the Cloud, all open source!
I really hope to have time to work on some cool things to add more foggy-cloudy stuff and have things running on a real cloud infrastructure. I have many ideas in my mind these days and it is really really really cool.
Oh and I will also talk a bit about what we are currently building in the Play FP7 project. We have to show things in two weeks at the European Commission and these things are really interesting to share with OW2 attendees and staff.
BTW, I think that there is some free beer social event this year at OW2Con, see you there of course!

I spent one hour playing with the [Play Framework](http://playframework.org) and WebSockets in order to push some (SOAP) messages received on some Web services hosted by the Play application to the clients browser.
The result is really amazing: We can simply push these SOAP messages to clients in less than 100 lines of code. There are some problems with some messages lost due to some conception problems but which are not Play ones. In fact, the current prototype just send the messages to all the clients but what should be done is creating streams per client with some ID to identify them…
The source code is available on GitHub at [https://github.com/chamerling/play-soap-websockets](https://github.com/chamerling/play-soap-websockets)

I am using GitHub more and more: for personal open source projects (https://github.com/chamerling), for research projects (Play for now https://github.com/organizations/play-project), for organizations (OW2 will start using it soon at least for mirroring https://github.com/organizations/ow2, and we use it for the Java USer Group we created in Montpellier https://github.com/organizations/Jug-Montpellier).
This is a really nice tool and not only one other fashion tool. There are tons of interesting features and thousands mature and interesting projects are already there.
I remember a discussion almost one year ago where someone in my company was saying that git was not ready for industry. To be honest, I was not using git at this moment and did not have time to look at it, so my opinion was… no opinion. But what I can say today is that, after some months of use and with all the work GitHub guys did and with all the projects which migrated to this platform, it is probably more than ready to be widely used by all (not only GitHub, but git too).
So to come back to the main goal of this article, I was asking on twitter some days ago, what is the best tool to use to publish GitHub gists?
Vous utilisez quoi comme client pour faire vos gist@github sur OSX?—
Christophe Hamerling (@chamerling) August 17, 2011
Even if I got some retweets, I did not have any answers (probably since I do not have any impact on Twitter or maybe my followers are not GitHub users…). So I asked it to GitHub and the first answer is just what I need: A command line tool written in Ruby (which is published by the GitHub CEO itself) and which is named gist. Using it is sooooo simple, just launch your terminal (I still use it everyday for many things) and the gist command will do the rest. As a result, you will get the gist link you can send to your peers. Sharing a gist just take 3 seconds…
And you what are you using to gist? or even are you using Git?

PetalsLink ce n’est pas juste Petals ESB. C’est aussi toute une collection d’outils complémentaires pour créer une véritable pile Open Source. Bertand Escudié, Président de PetalsLink, donne un aperçu de notre vision dans cette vidéo tournée lors de SolutionsLinux 2011.
Tant qu’on y est, PetalsLink s’agrandit et cherche des consultants pour développer le business sur Paris. Des postes en R&D sont aussi ouverts sur Toulouse.

Comme le reste des talks proposés par la communauté OW2 à OSCON 2011, le mien a aussi été rejeté. Pourtant le titre sonnait bien “Cloud Service Bus – a public, private and hybrid cloud integration approach for SOA” .Bizarre… Serait ce parce que nous ne sommes pas sponsor de la conf, parce que nous sommes mauvais, ou pire bon mais Français? Ah non c’est le Cloud, c’est has-been. Dommage, j’avais des choses presque intéressantes à raconter, vous en pensez quoi?
Oh!?
Gartner predicts that by 2012 20% of businesses will own no IT assets. A key aspect of this trend is the move towards cloud-enabled services. Open source solutions are key enablers of this trend. This talk will explore how a fully open sourceSOA-based solution can use the Cloud to open and extend enterprise software infrastructure.
The attendee will first learn how a Cloud-aware SOA software infrastructure can be built combining an Enterprise Service Bus [http://petals.ow2.org] and a Cloud infrastructure framework [http://opennebula.org]. This creates a ‘Cloud Service Bus’ which will allow the integration of in-house services in order to benefit from Cloud-based features such as elasticity, load balancing, service clustering and migration. Then, the talk will go one step further: by using the Cloud framework capabilities, the Cloud Service Bus can be extended to a hybrid approach combining both public and private Clouds. This shows the attendee how to bring the advantages of modern cloud based solutions to legacy enterprise applications while keeping sensitive data and services inside the enterprise. A Cloud-based SOA solution needs to be governed, monitored and managed in a totally transparent way akin to a traditional SOA solution; throughout the presentation the talk will show how the Cloud Service Bus approach does not break the SOA paradigm.
This work is part of the Open Source Cloudware Initiative launched by the OW2 Consortium [http://www.ow2.org/view/Cloud/] and uses research work from the SOA4All [http://soa4all.eu] and Play [http://play-project.eu] European Commission Cordis FP7 research projects.
A suivre, en vrai, autre part…
