Explore resilient architecture principles in this 50-minute Devoxx conference talk by Matt Stine. Learn how modern approaches enhance system resilience through observability, well-known patterns, and chaos engineering. Discover techniques for creating resilient systems using Spring Boot, Spring Cloud, Spring Retry, Netflix Hystrix, and Chaos Engineering. Gain insights into measuring success, enhancing observability with golden signals and tools like Actuator and Zipkin, and implementing resilient patterns such as retries, bulkheads, and circuit breakers. Understand the importance of embracing chaos through practices like Game Day Exercises and Chaos Monkey. Benefit from Stine's extensive experience in enterprise IT and cloud-native application architectures as he guides you through the evolution from mistake prevention to resilience in system design.
