The Nexus of Forces (cloud computing, social, mobile, and information) is a major challenge for IT strategy. I believe culture is the key for capturing the benefits of cloud computing, social business practices, mobile and information processing.  Gartner identifies five core principles for a nexus-enabled application architecture:

These principles evolve to developing cloud-first applications, which require a cultural transformation of the enterprise to be successful. Cloud-first application architectures embody collaboration, for services to be effectively utilized they need to be shared. For enterprise culture, this means InnerSourcing. Lines of business sharing value they create for others to use and build on. Establishing a collaborative culture also leads to a continuously planning one, which will only tighten alignment across enterprise layers and drive successful innovation.
