AWS Cluster Prep: Configuring Availability Zones and SSH Keys

Setting up a production-ready Kubernetes cluster requires a rock-solid infrastructure foundation. Before deploying a single container, you must design your network for high availability and secure your cloud access. This text-based course guides you through the essential prerequisites of cluster setup on AWS, focusing on resilient Availability Zone (AZ) distribution and secure SSH key infrastructure. You will transition from understanding basic cloud concepts to planning robust, production-grade access controls and network layouts. What you'll learn: - Understand the core concepts of high availability, fault domains, and AWS Availability Zones. - Design a multi-AZ subnet architecture to ensure your Kubernetes nodes survive infrastructure outages. - Create and manage secure SSH key pairs, using modern algorithms like ED25519 for robust authentication. - Configure secure access control lists and security groups to protect your cluster nodes. - Explore modern alternative access methods, including AWS Systems Manager Session Manager for passwordless entry. - Apply infrastructure-as-code principles conceptually to plan your cluster network layout. You will start with foundational cloud resilience concepts before moving step-by-step through key generation, region planning, and network isolation strategies. This course is designed for beginners in cloud engineering and DevOps, requiring no prior Kubernetes experience—just a basic familiarity with cloud concepts.
