If you want to break your monolith into components, services, or even functions, it is important to understand where and how to break your existing code base and architecture into smaller units to allow it to scale and perform, and to make it easy to operate. This session, a representative from Dynatrace shows how the company redefined its architecture, explains which migration capabilities its engineers built into its product, and describes how the lessons learned can benefit everyone as they fearlessly transform from monolith to serverless.
