Building Resilient Microservices with Polly and Fault-Tolerant Patterns

Modern distributed systems are bound to face network glitches, transient faults, and downstream service outages. To build reliable software, your applications must be designed to withstand these failures gracefully without crashing. This text-only course guides you through the foundational concepts of application resiliency and error management in microservices. You will learn how to safeguard your event-driven architectures against unexpected disruptions using industry-standard patterns and the Polly library. What you'll learn: - Understand core resiliency concepts, including transient faults, cascading failures, and redundancy. - Implement essential resiliency patterns such as retries, circuit breakers, fallbacks, and bulkhead isolation. - Configure Polly policies and modern resilient pipelines to handle API and message broker failures. - Apply error-handling strategies tailored for event-driven microservices and asynchronous message processing. - Integrate observability and telemetry to monitor system health and detect failures early. The course begins with foundational definitions of system availability and fault tolerance before progressing to practical configuration of Polly policies. You will explore structured, text-based scenarios that demonstrate how to protect your services from real-world network instability. Designed for backend developers and software engineers new to distributed systems, this course requires only basic programming knowledge and no prior experience with resiliency frameworks. Start reading today to build microservices that remain stable and responsive under any conditions.
