Cloud Native Application Architecture is a comprehensive course on Udacity that covers the fundamentals of building and deploying cloud-native applications. Students will learn how to structure, package, and release an application to a Kubernetes cluster using an automated CI/CD pipeline. The course starts with applying good development practices and packaging the application with Docker. Students will then explore Kubernetes resources and learn how to deploy the application using k3s. The course also covers template configuration managers like Helm for parameterizing Kubernetes declarative manifests. Towards the end, students will learn about Continuous Integration and Continuous Delivery (CI/CD) using GitHub Actions and ArgoCD to automate the release process. Additionally, the course includes modules on refactoring microservices, observability in distributed systems, and microservices security. Overall, this course provides a comprehensive understanding of cloud-native application architecture and equips students with the necessary skills to build and deploy scalable and secure applications.
