A CIO’s Guide to Cloud Application Migration Robert Christiansen Best practices for building your Minimum Viable Cloud and preparing for large-scale application migration. Do you want to be in the data center business? We didn’t think so and you’re not alone. Most CIOs have a deep desire to get out of the data center business. Corporate leadership, understanding the benefits of public cloud, are directing IT to reduce costs. Therefore, many IT executives are turning to public cloud as a model for reduced total cost of ownership (TCO). This requires a significant migration of application workloads out of data centers and into public clouds. Our experience points to an average TCO savings of 40% year-over-year, achieved through what we call Migration @ Scale - moving application workloads to public cloud providers using a factory model. We’ll discuss the specifics of this factory approach later on in this guide. A successful cloud program requires a basic change of mindset. It groups have traditionally approached big projects as if they were launching a rocket: make or acquire the components, install them, test everything, put it all on a launch pad and send it off. With cloud adoption, this approach presents too many opportunities to get it wrong. It also traps IT in the ‘Tyranny of How’, paralyzed by analysis, evaluation, preparation, planning, strategizing and a host of issues that get in the way of actually doing something meaningful. There is, however, a fundamental concept that is proven to break the old thinking paradigm. We call it the MVC, or Minimum Viable Cloud, built on the same premise as the MVP, or Minimum Viable Product, from the book, The Lean Startup. In the MVC we teach clients how to iterate their cloud program to prepare for Migration @ Scale. Iteration can be a hard concept to embrace, requiring IT execs to abandon their waterfall model of data center management. In the new model, infrastructure is code. The public cloud lets you use software to create the data center. Whether it is Chef, CloudFormation, Puppet or Ansible, software 70 | THE DOPPLER | FALL 2016
