Resistance, cost, and uncertainty are significant challenges associated with large-scale technical cloud migration strategies and execution. To overcome these obstacles, organizations need to unblock common challenges, understand app dependencies and assessing costs, leverage their cloud and tech providers, and adopt a strategic advisory partnership approach. A successful cloud migration involves three stages: planning, migration, and running, which require defining the work involved in moving applications to the cloud, leveraging real-time data and tracking resource usage, and optimizing work environments to reduce time and cost. The Nimbus app, built on New Relic One, provides an actionable, real-time user interface to track workloads through key stages of planning, migration, and running in the cloud, enabling organizations to accelerate and de-risk their cloud optimization journey.
