The Importance of Event-First Thinking
For global businesses to meet today’s architectural challenges with constant change and extreme scale, we need to go back to the basic principles of system design. The common element in the problems we face is the notion of events driving both actions and reactions, Neil Avery writes in a series of blog posts describing why events are so important and the advantages of an event-first approach .

Are Frameworks Good or Bad, or Both?
Preferring frameworks or libraries is somewhat controversial, Frans van Buul, Evangelist at AxonIQ, the company behind Axon Framework, writes in a recent blog post. Many argue in the favour of libraries but Van Buul thinks that a framework can be very valuable when building business applications. He believes this to be especially true for applications based on CQRS, DDD and event sourcing.

Experiences Moving from Microservices to Workflows at Jet.com
The Order Management System (OMS) at Jet was originally developed using a collection of microservices orchestrating tasks. As the company grew, the challenges with this architecture also grew until they decided to build a new workflow-based platform. In a blog post, James Novino at Jet describes the challenges with their old system and an overview of the new platform.

Russ Miles: Ignored Architects and Chaos Engineering
At the recent Event-Driven Microservices Conference in Amsterdam, Russ Miles claimed that the biggest challenge for an architect is that you get ignored. You have great ideas like event-driven microservices, but the reaction too often is that it sounds good, but that it’s overly complicated for the needs at hand.

Designing Microservice Architectures the Right Way: Michael Bryzek's Lessons Learned at QCon NY
At QCon New York 2018, Michael Bryzek discussed how to design microservice architectures “the right way”. Key takeaways included: engineers should design schema first for all APIs and events, as this allows the automated code generation of boilerplate code; and investment should be made in automation, such as deployment and dependency management.

QCon NY: Jonas Bonér on Designing Events-First Microservices
Events-first domain driven design (DDD) and event streaming are critical in developing a resilient and scalable microservices architecture. Jonas Bonér from LightBend engineering team spoke at QCon New York 2018 Conference last week about the events-first design.

Experiences from Building an Event-Sourced System with Kafka Streams
At the recent JEEConf conference in Kiev, Amitay Horwitz described how he and his team implemented an event-sourced invoice system, the challenges they experienced after running in production for 2 ½ years, and how they implemented a new design using Kafka Streams. The new design is still under assessment, but they do heavily use Kafka in production.

Business Processes, Long-Running Services and Microservices
During recent years domain events are increasingly being discussed, but we should be discussing commands just as much, Martin Schimak explained at the recent DDD eXchange 2018 conference, where he covered events, command and long-running services in a microservices world, and how process managers and similar tooling can help in running core business logic.
