This document discusses Spring Cloud and Docker/Kubernetes for building cloud native applications. It provides an overview of Spring technologies like Spring Boot and Spring Cloud and how they can be used to develop microservices. It then discusses how to containerize services using Docker and deploy them on Kubernetes. The document outlines the steps in a cloud native journey from initial monolith application to containerized microservices deployed with Kubernetes using technologies like Spring Cloud.
