Modernizing Traditional Apps with a Docker is a great way to start your containerization strategy and to prove to your leadership there is value. MetLife has outlined the early stages of their journey at past DockerCons, but have now moved past the POC stage and are in the process of transforming our technology portfolio globally. We are driving change on multiple levels in many ways, and now we've created a long-term strategy outlining how we will reach our technology goals using containers. At MetLife, we realized that once a PoC is complete, incorporating an entire application portfolio can be challenging: Where do you focus for the largest benefit to the organization? How and what do I spend the savings on if I want to ensure maximum value? How should people & processes change to align to match our transformation goals? In this session you’ll hear more about how MetLife has built their strategy to go forward, and you’ll learn how Docker's strategic approach to containerization and transformation can be applied in your company, too. A proof of concept is a great way to see if your traditional applications are worth Dockerizing. However, getting that first application into production in an enterprise can pose many challenges, both technical and organizational. In this talk, I will take you through the journey starting with high-level decisions such as what applications and components to Dockerize and methodology, then move on to more detailed decisions such as what components to put in images, configuration management, and version control. I will also cover how this impacts the development pipeline and strategies for operationalizing and scaling out the application onboarding process.
