Juniper, Mirantis Offer Software-Defined Networking Tools for OpenStack Clouds

Mirantis, one of the movers and shakers on the OpenStack scene, and Juniper Networks have announced an expanded engineering partnership focused on an open-source software-defined networking (SDN) fabric to deploy OpenStack clouds at scale. Mirantis’ OpenStack distribution will now support and interoperate with Juniper Contrail Networking, an SDN solution for enterprise and service provider customers. Mirantis OpenStack also supports and interoperates with OpenContrail, an open source SDN solution.

Notably, this news immediately follows the announcement that Juniper Networks and Canonical have expanded their existing  partnership and will oversee co-development of a carrier-grade, OpenStack software solution as part of Contrail Cloud. Juniper is quietly stringing together a formidable OpenStack-centric strategy.

Fedora Seeks a Diversity Advisor

The Fedora project is looking for somebody to become its diversity advisor. “The Fedora Diversity Advisor will lead initiatives to assess and promote equality and inclusion within the Fedora contributor and user communities, and will develop project strategy on diversity issues. The Diversity Advisor will also be the point of contact for Fedora’s participation in third-party outreach programs and events.” You have to get to the bottom of the announcement to read that this is a volunteer position, though they hope to change that someday.

Open Source Works, Just Ask Facebook

FACEBOOK LIKES TO share its toys. Over the years, the company has released the source code and designs formany of its internal projects, allowing the rest of the world to use them, modify them, and build on them—all for free.

Plenty of companies are now releasing open source projects in the hopes that other companies will help improve their software, but Facebook stands out because its projects actually end up being used by so many others. A startup called Datastax built an entire company to support users of Facebook’s database Cassandra, and now even Apple is exploring the use of Facebook’s ambitious server designs in its data centers.

So it’s no surprise that one of Facebook’s newest open source projects, Presto, is winning over outside companies too.

Intel VP Mauri Whalen: “If You’re not Collaborating, Development Will Happen Without You.”

Editor’s Note: This article is paid for by Intel as a platinum-level sponsor of the Linux Foundation’s Collaboration Summit conference and was written by Linux.com.

Mauri WhalenIntel has been a leader in the Linux kernel community for almost two decades – and was named the no. 1 corporate contributor to the kernel for 2014, according to the recent Who Writes Linux report. The company’s influence also extends into the broader open source community, where Intel stands out as a model for how to effectively engage in projects and incorporate open source strategy into product development.

As enterprises increasingly turn to open source practices to remain competitive in the global economy, they often cite Intel’s long-standing open source program as a goal for their own efforts. When it comes to navigating open source communities, license compliance, developer recruitment, and other challenges specific to open source participation, Intel has the process dialed in – and for good reason.

“Open source is a strategic advantage for us,” said Mauri Whalen, Intel vice president and director of Core System Development in Intel’s Open Source Technology Center. “To take advantage of strategy and innovation that happens in the community is very important.”

Why Intel Invests in Open Source

First and foremost, participating in open source communities allows Intel to optimize its silicon to the many ways that customers use it, Whalen said. By working with users across open source communities, Intel can develop features that allow its customers’ software to take full advantage of the CPUs, chipsets and other Intel hardware.

Being deeply involved in open source also gives Intel early visibility into new and innovative projects and features, she said. Intel can move quickly to ensure its own software and hardware enable these new trends and stay on the leading edge of technology.

“Everybody is building products based on open source, and if you’re not out in the communities and not out collaborating all of this software is going to go on without you,” Whalen said. “Your code isn’t going to get out there, and you won’t take advantage of what others are doing that might make your software even better on your hardware.”

When Intel releases its own code and contributes to upstream projects, it allows Intel customers to get to market faster and with less cost by using code that Intel has already created – another strategic advantage for Intel.

“They don’t have to recreate the wheel because of the work done by open source developers at Intel,” Whalen said. “That part of the development is already done and the cost is sunk. When they have the code, they can maintain it, which is an advantage for the customer.”

Intel investment in open source development stretches back to the early 90s and continues today through participation in several Linux Foundation collaborative projects such as the Yocto Project, OpenDaylight, and Iotivity – and continues to prove an effective strategy. Companies just getting started in open source can learn from Intel’s lead.

Advice for companies new to open source

It’s been more than 15 years since Intel created its first Linux-based consumer device. The company has learned a lot about open source software and collaborative development since then.

But those just getting started don’t have the luxury of waiting 15 years to learn about open source. Today’s market demands a fast education.

Whalen’s advice for companies that are just starting to participate in open source? Take the time to learn how open source development works. Learn how to participate in a community and be a good community member, and then contribute, she said.

Start by networking with developers and other companies already doing open source in your industry, she advises. Talk to the people working on projects you’ll be contributing to.

“One of the best ways to do this is by attending conferences,” Whalen said. “The Linux community puts on so many conferences through the Linux Foundation, for example. You can get a wealth of information by going to these events and seeing what other people are doing and how they’re using open source to their advantage.”

Other suggestions: Ask how you will benefit from contributing to a community. Learn about how open source licenses work. Find and learn the best development tools and methods.

“I always find people in the community are extremely receptive to talking about how we should be working together,” Whalen said.

If you don’t have time to do the research yourself and you have the means, hire someone experienced in open source development to lead your efforts, she said.

“Open source is a collaborative environment,” she said. “Learn from others.”
