IBM's approach to open technology
For several years, IBM has been recognized as a leader in open technology, from its early work with Apache to its current work across all layers of the cloud stack and application development. This recognition comes on the back of tireless collaboration with fellow industry leaders and clients alike. The case for open is clear: Projects that are managed under open governance have been found to be more successful, have a longer life, and are less risky than proprietary projects. The most successful projects are those that ensure interoperability and portability, and address various other enterprise needs such as security, scalability, and accessibility. IBM isn't just an open source consumer; it is also an ardent contributor to several projects, including Eclipse, Linux, OpenStack, Cloud Foundry, Node.js, Docker, Hyperledger, and many more. The company's ongoing commitment to open technology is viewed as a means to form the very foundation of enterprise systems and solutions.

Changing the mindset to get the most out of cloud, Part 3: Our top 11 lessons learned
Although it's widely agreed that cloud computing has tremendous potential, very few cloud projects actually deliver the expected results in full. In most cases, this underachievement is due to a lack of understanding of cloud and how it can reduce technical costs. This three-part series focuses on what it takes to make an IT solution that can maximize the benefits of cloud by adopting cloud best practices in the areas of application design, development processes, and IT management processes. In Part 1, we explored how cloud solutions are different from traditional web applications. In Part 2, you saw how cloud-ready applications can foster true agile development. In this final installment, we show you how to adapt your development process to leverage the full potential of cloud, based on lessons learned in a real development project here at IBM.

Reader favorites: Top 5 cloud computing tutorials for 2015
As you may have noticed, much of the cloud computing content we've published on developerWorks this year has focused on IBM Bluemix. Indeed, I've already posted a list of our top 5 Bluemix tutorials for 2015. But there's a whole lot more to developing for cloud than that one (very powerful) product. That's why I've pulled together this separate list: top 5 developerWorks tutorials published in 2015 that focus on cloud topics other than Bluemix. I chose these based on developerWorks traffic data for 2015 to date -- that's right, these are your favorites for the year.
