The Rise of Reactive Microservices

David Leitner

Every architecture buys options but demands payment in complexity. Stop slicing services by data objects with brittle synchronous APIs. Learn when to actually transition to reactive microservices.

Slicing software services along customer journey boundaries

Why organizing microservices by entities creates communication bottlenecks and slows down feature delivery.

#5 about 5 min

Bridging the customer journey and entity data mismatch

Addressing shared data dependencies across user flows by clarifying data ownership instead of caching.
