In the course Monolith to Microservices at Scale on Udacity, you will learn the principles and best practices of designing microservices architectures. You will explore different designs and strategies for dividing applications into microservices. Additionally, you will gain hands-on experience with containers using Docker, building and running container images, and storing them in a container registry. The course also covers automating the application development lifecycle, including understanding the benefits of continuous integration and continuous deployment (CI/CD) and using tools like Travis to build CI/CD pipelines. You will learn about orchestration with Kubernetes, configuring and launching auto-scaling, self-healing Kubernetes clusters, and deploying microservices using Kubernetes. The course also delves into best practices and design patterns for Kubernetes in production, such as implementing service registration and discovery, configuring scaling and self-healing, securing microservices, and implementing monitoring and logging for microservices deployment. Finally, you will apply your knowledge in a course project where you will refactor an existing application into a microservice architecture, build a CI/CD process that automatically deploys Docker images to a Kubernetes cluster, and configure the cluster to address common challenges related to scale and security.
