How did you first hear about OpenContrail and what was your initial reaction?

In the scope of eNovance service for CloudWatt, I attended a CloudWatt session on SDN and networks overview (MPLS/BGP) where the speaker also spoke about OpenContrail and gave us the pointer on the OpenContrail ebook gave me real clear and concise view of the OpenContrail project and its capabilities. It was very interesting, and I wanted to know more about it.

What made you decide to download the OpenContrail code and play around with it? Any particular driver or work initiative?

CloudWatt had studied the corporate version of OpenContrail, but the real trigger was the opening of the code with Apache2 license. OpenContrail was open, very easy to download and deploy, so, we decided to contribute to the packaging effort launched by Pedro Marques. Together with Romain V. from CloudWatt and Sylvain B., we also created a continuous integration system to builder packages, which was installed on a pool of nodes to verify the installation. This capability allowed us to quickly converge on the remaining software development and testing efforts.

What work have you done with the OpenContrail code? Tell us about it and what value it might have to others?

I worked with Pedro M. and Ted G. on the packaging of the community version of OpenContrail. We have made a lot of enhancements together and we will soon release 1.06 version which will be the first community version of OpenContrail. PPA (Personal Package Archives) has been created (ppa:contrail/ppa) to enable installation of OpenContrail with just an « apt-get » command without the need to compile all the code. Using the capabilities of a simple configuration management tool, we will be enabling very easy installation of OpenContrail by handling the packaging and management of all dependencies including those even in upstream distributions. Debian and Ubuntu will receive these packaging enhancements soon based on the normal cycle releases.

What has been your experience in working with the OpenContrail team?

OpenContrail team was very productive and dynamic, either on the mailing list or IRC, with relevant and interesting information exchanges! Regular weekly meetings on IRC has been extremely useful. I mostly worked with Pedro, and it was very interesting, we extensively used the reviews system to take advantage of the different time zones, and of course to validate each other.

What would you like to see improved with the OpenContrail code or overall community?

Maybe a continuous Integration system like the one OpenStack has, that has reviewing capabilities providing a clear view of patch set, well integrated with bug tracker, and of course pre-merge validation functionality. But I was also informed that this capability will be coming soon. A unique place for documentation would also be a good improvement similar to what OpenStack’s, as currently some of the documentation is inside a github wiki, and some other parts are on OpenContrail website.

What do you think the real value of SDN or NFV will be for you or your industry?

Cloudwatt is a cloud provider based in France and they use SDN as the backbone of their cloud solution. SDN basically allows Cloudwatt to provide virtual private networks inside the datacenter and cross-datacenters. NFV is the next step, we will soon work on service VM insertion using routing policies. In short SDN makes network easy to provision, easy to upscale.

What is your overall perception of the importance of open source in SDN/networking/technology/innovation?

There would be no Internet as we know it today without free software, both are inseparable (RFC based, open standard), Free and open software is a great vector for sustainability and development, I am very pleased that Juniper goes in this direction because it will facilitate interoperability between existing open source network solutions with high performance Juniper hardware.
