This document discusses strategies for modernizing applications and replatforming them using Project Kubernetes Service (PKS). It outlines how companies have different options for packaging and running workloads, such as using containers, microservices, serverless functions, and monolithic applications. PKS aims to provide the right runtime for each workload type. The document compares container orchestrators, application platforms, and serverless functions, noting that PKS aims to push workloads higher in the platform hierarchy for more flexibility and less enforcement of standards while lowering development complexity and improving operational efficiency. It provides recommendations for getting started with migrating workloads to PKS, such as lifting and shifting applications with minimal modernization, leveraging platform capabilities, and fully modernizing
