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.

#1 about 2 min

Tracing the evolution of modern microservices architecture

An introduction to the progression of distributed software architecture.

#2 about 5 min

Understanding the challenges of synchronous microservice integration

How HTTP synchronous calls between services face latency spikes and cascading failures.

#3 about 2 min

Decoupling microservices with asynchronous messaging queues

Migrating to an asynchronous message-driven architecture to protect high-latency core systems.

#4 about 6 min

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.

#6 about 3 min

Pushing data streams into isolated read models

Using the CQRS pattern to push state changes into service-specific persistent projections.

Managing trade-offs and latency in eventual consistency

How to handle eventual divergence, eventual variance, and eventual latency in distributed read models.

#8 about 5 min

Optimizing system scalability and real-time push capabilities

Utilizing reactive pipelines and GraphQL subscriptions for autonomous services and push-based frontend updates.

#9 about 2 min

Integrating legacy monoliths with change data capture

Capturing database log events to decouple reactive services from legacy system constraints.

#10 about 6 min

Maximizing data throughput via distributed stream sharding

Partitioning event topics to enable infinite processing scalability with localized projections.

#11 about 4 min

Weighing architectural complexity against system scalability options
