AWS Route 53 Foundations: DNS, Domain Registration, and Routing Policies

Modern cloud architectures rely on high availability, and managing how traffic reaches your applications is a critical part of that stability. This text-based course introduces you to the core principles of Domain Name System (DNS) management using AWS Route 53, giving you the skills to handle domain registration and global traffic routing with confidence. You will transition from understanding basic IP address mapping to configuring advanced routing policies that keep your applications online even during regional outages. What you'll learn: - Understand foundational DNS concepts including records, zones, and name resolution - Register and manage custom domains directly within the AWS ecosystem - Configure health checks to monitor the availability of your web applications - Implement routing policies such as failover, latency-based, and geolocation routing - Integrate Route 53 with other core AWS services for seamless traffic flow - Apply modern security best practices to protect your domain configurations Starting with basic terminology and core DNS concepts, this course guides you through structured text explanations and real-world scenarios to build your cloud networking skills. You will explore how to design resilient architectures that automatically redirect traffic away from unhealthy endpoints. This course is designed for beginners new to cloud networking, system administration, or AWS, with no prior DNS experience required. Start building more reliable and scalable cloud setups today.
