Explore patterns for scaling and operating large-scale distributed systems with microservices and databases in this 40-minute Devoxx conference talk. Learn how to handle distributed transactions, scale data beyond a single data center, manage eventual consistency, and migrate data and schemas without downtime. Discover solutions to challenges faced when microservices and large-scale operations intersect with databases. Gain insights from Wix.com's experience operating hundreds of microservices and managing petabytes of data across multiple datacenters and clouds. Examine topics such as universal architecture, replication conflicts, future toggles, consistent trade-offs, and separating read/write services. Adapt these patterns to improve data handling in your own large-scale distributed systems.
