Zero Data Loss at Scale

Learn how to achieve zero data loss in large-scale distributed systems through this conference talk from Conf42 SRE 2025. Explore the fundamentals of microservice architecture and asynchronous systems before diving into the specific challenges that distributed systems present for data integrity. Discover the critical impact these challenges have on Site Reliability Engineering practices and understand comprehensive strategies for preventing data loss at scale. Master advanced recovery techniques and learn to design robust distributed acknowledgement protocols that ensure message delivery reliability. Examine standardization approaches for message formats that enhance system interoperability and reduce failure points. Analyze performance optimization strategies while understanding the crucial trade-offs between consistency and performance in distributed environments. Apply these concepts through a detailed case study that demonstrates real-world implementation of zero data loss architectures, concluding with key takeaways for implementing these practices in your own systems.
