Business Processes, Long-Running Services and Microservices

by Jan Stenberg Follow 34 Followers on  Jun 28, 2018 2

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.

Events Should Be a First-Class Tool for Developers

by Jan Stenberg Follow 34 Followers on  Jan 29, 2018

We should use events much more often in software systems, Randy Shoup declared in a recent blog post about how events should be first-class citizens in systems. He believes we often underestimate the value of events as a tool. One example is that they can help us decouple parts of a system so that we can reason about them independently.

Event Sourcing in an Unreliable World

by Jan Stenberg Follow 34 Followers on  Nov 30, 2017

Examples of event sourced systems are often from process-oriented domains, like e-commerce, with incoming commands that generate events. But there are domains without processes that are intrinsically unreliable where we are collecting events from external event sources with transports that are unreliable, Lorenzo Nicora explained at the recent Microservices Conference µCon London 2017.

Vaughn Vernon Uses Reactive DDD to Model Uncertainty in Microservices

by Thomas Betts Follow 38 Followers on  Oct 09, 2017 6

Microservices and reactive systems bring with them uncertainty about messages arriving out of order, multiple times, or not at all. How to react to such uncertainty is a business decision, says Vaughn Vernon, and is best captured by modeling the uncertainty using concepts of Domain-Driven Design.

Selecting an Event Architecture

by Jan Stenberg Follow 34 Followers on  Aug 24, 2017

When designing a distributed system, maybe based on microservices, and you are considering an event architecture, there are several models and technologies available. When choosing how to implement the architecture the non-functional requirements are a main factor, David Dawson claims when describing different styles of event architectures in a recent blog post.

Moving from Transactions to Streams to Gain Consistency

by Jan Stenberg Follow 34 Followers on  Mar 13, 2016

With many databases in a system they are rarely independent from each other, instead pieces of the same data are stored in many of them. Using transactions to keep everything in sync is a fragile solution. Working with a stream of changes in the order they are created is a much simpler and more resilient solution, Martin Kleppmann stated in his presentation at the recent QCon London conference.
