If your next software development project is going to be successful, be it a simple Java EE deployment or a full-scale role out of a private cloud initiative based on OpenStack, a tremendous amount of code has to be written. The sad state of affairs enterprise organizations need to reckon with is that there is no way all that code can be written by the internal development team.

So what's an organization to do? According to Jim Zemlin, executive director of the Linux Foundation, successful organizations reach out to the open source community. "There is too much software to be written for any one organization to write this software on its own," Zemlin said. "Open source allows businesses to focus on only the most important aspects of their technology stacks; only the things that truly differentiate the organization."

Dr. Stephan Lenz, IT infrastructure manager at BMW Group, has firsthand experience with the benefits both virtualization and open source software can bring to an organization. BMW was far ahead of the curve in recognizing the benefits of a highly virtualized, containerized type of infrastructure. But by about 2011, because changes to traditional development and deployment processes were providing only marginal improvements, the company was looking for new ways to build efficiencies into its IT stack. "We could not become more cost efficient with conventional methods, and we would lose our competitive advantage if we did not do something new," Lenz said. "The new thing that we saw on the market was cloud."

The dangers of in-house development In-house projects were developed to provide a virtualized, cloud-based system that made BMW's global data centers more productive. "In about 2011, we developed a piece of software internally and we called it our own internal cloud," Lenz said. "It worked perfectly. We got new efficiencies. Everything was great. And then we ran into trouble. Things wouldn't always go like we thought." Of course, BMW is an automobile manufacturer and not in the business of data center development. It's more than understandable that their internally built systems simply couldn't deal with every single corner case that arose. And that's where OpenStack came in. After some due diligence and evaluation, BMW realized that this open source piece of software could perform many of the key virtualization and automation tasks they needed, while at the same time removing the need for every line of code to be developed, managed, tested and maintained in-house.

The benefits of open source initiatives The two big advantages OpenStack provided BMW? "First, we have an API and a data model to describe cloud and virtual instances that will become industry standards," Lenz said. This allows large organizations like BMW to go forward with confidence, so that development will be stable and tool chains and code will not have to change as the industry evolves. And the second key benefit is the fact that OpenStack is open source and free. "Nobody earns money on the growth of our company. Nobody comes with unexpected license fees, and we have experienced that a lot." The BMW experience underscores the reality that in many cases, turning to open source initiatives can provide significant benefits to an organization and help unburden IT departments from having to maintain internal software projects that can rival even the biggest Apache projects in terms of size and complexity. There is always a need for customization, but blending a good deal of open source software with a temperate mix of internal development is what most organizations are discovering to be the magic ratio.
