What is Cloud Computing?
What is cloud computing? It may seem odd for me to be asking that question today given “the cloud” has been around for years and it absolutely dominates the information technology landscape. I actually addressed this question in a blog post I wrote two years ago. At the time, many people I encountered were struggling with the term and the litany of differing and disparate ‘expert’ views didn’t help this situation. My article focused on the definition developed by Peter Mell and Tim Grance at the National Institute of Standards and Technology (NIST), “The NIST Definition of Cloud Computing”, NIST Special Publication 800-145.
In the two years since I wrote my post, cloud adoption has continued to grow and there is no end in sight. Though the potential benefits of cloud computing are off-the-chart, this incredible information technology advance poses new threats in my quest to help eliminate the “us and them” divide between IT organizations and the businesses they serve. In my last post, I talked about the onset of “Shadow IT” - IT systems and IT solutions built and used inside organizations without organizational approval. Cloud-based applications and services represent one of the primary Shadow-IT conventions. Many business units are in danger of undermining their enterprise goals by making unilateral and potentially harmful information technology decisions. This is tragic because sound cloud computing decisions could realize phenomenal potential for almost every organization. I also find it ironic because one of the themes of my latest presentation and workshop, “Ensuring Cloud Computing Success,” is how IT and the business can use cloud computing as a catalyst to act as “one.”
