This conference talk from SREcon25 Americas explores how to hijack service discovery mechanisms to effectively simulate dependency degradation. Presented by Abdulrahman Alhamali from Shopify, learn about the challenges services face when dependencies degrade through slowdowns, bandwidth limitations, or complete outages. Discover how to proactively test resilience mechanisms like circuit breaking, bulkheading, and graceful degradation without waiting for actual incidents. The presentation introduces innovative approaches to streamline traffic forwarding for simulation purposes by manipulating service discovery, offering alternatives to traditional proxy-based solutions. Perfect for SREs and developers looking to enhance system reliability through practical testing methodologies.
