Introduction to Kubernetes: Transitioning from Monoliths to Microservices

As applications grow, traditional monolithic architectures become difficult to scale, update, and maintain. Transitioning to microservices solves these problems, but managing dozens of independent services introduces a brand new set of infrastructure challenges. This text-based course guides you through the evolution of software architecture and shows you how Kubernetes simplifies container orchestration for modern applications. You will start by learning the foundational concepts of software architecture, comparing monolithic systems with microservices, and understanding why containerization is essential. By the end of this course, you will understand how to design, deploy, and manage scalable applications using Kubernetes. What you'll learn: 1. Understand the core differences between monolithic and microservice architectures. 2. Learn containerization fundamentals and how containers isolate application environments. 3. Explore Kubernetes architecture, including nodes, control planes, and pods. 4. Configure declarative deployment files to manage application state and scaling. 5. Apply basic service discovery and load balancing within a cluster. 6. Discover modern microservices patterns, including basic observability and GitOps workflows. Through clear written explanations and practical configuration examples, you will follow a logical path from basic architectural theory to deploying your first containerized services. This course is designed for software developers, system administrators, and aspiring DevOps engineers who are new to container orchestration. No prior experience with Kubernetes is required, though a basic familiarity with command-line interfaces is helpful.
