AWS Developer: Application Observability and Troubleshooting

Building cloud applications is only half the battle; knowing how to monitor, debug, and optimize them in production is what separates beginners from professionals. This text-based course guides you through the essential AWS tools and modern observability practices needed to keep your applications running smoothly. Through clear, written explanations and practical configurations, you will transition from guessing why an error occurred to pinpointing issues in real time. You will master the fundamentals of cloud monitoring, structured logging, and distributed tracing to build highly resilient systems. What you'll learn: 1. Understand core observability concepts, including metrics, logs, and traces. 2. Configure AWS CloudWatch to collect, analyze, and alarm on critical application metrics. 3. Implement distributed tracing with AWS X-Ray to track requests across microservices. 4. Apply structured logging practices to make your application logs searchable and actionable. 5. Troubleshoot common cloud application failures and performance bottlenecks systematically. 6. Set up automated alerts to detect and resolve production issues before they impact users. The course begins with foundational definitions of cloud monitoring and observability before diving into step-by-step configuration guides. You will explore practical scenarios, learn how to read trace maps, and establish robust logging standards for modern cloud environments. This course is designed for beginner cloud developers, software engineers, and system administrators looking to build reliable AWS applications. No prior monitoring experience is required, though a basic understanding of cloud concepts is helpful.
