If you were to sneak-peek into AxonIQ’s internal chat, you’d quickly notice that the following comic from xkcd.com pops up once in a while in quite a few channels. This comic serves as a constant reminder that no matter how many times we explain something, there will always be more…

Author: Ben Wilcock I’m not a big fan of TV murder mysteries for two reasons. The first is that you must watch for hours (sometimes weeks) before the killer’s fatal mistake gets revealed. The second is that the ending is often predictable. …

Here, there’s a legal requirement to deliver services and information into the hands of citizens, all day, every day, all year round. In a conventional organization, this would be difficult enough. …

In my previous Blog on running a containerized Axon Server, I spent just a little bit of text on the challenges of using a single StatefulSet scaled to the number of nodes we want in the cluster. Also, I completely skipped the subject of using Helm to manage the deployment…

CQRS/ES are patterns and to be more specific they are Application Design patterns and their implementation spans across 3 main Architectural areas (*). Structural i.e. Reliability/Availability/Scalability/Robustness and Continuity Operational i.e. Maintainability/Configurability/Portability/Upgradeability and Extensibility Cross-Cutting i.e. Security/Privacy/Supportability and Usability To help pinpoint the exact implementation areas, let us look at two…

So your organization is toying with the idea of using Event Sourcing, the benefits look promising but you can’t seem to shake off the nagging doubt of that one aspect of adoption — Eventual Consistency because of its alignment with CQRS. Your organization’s systems have always been following the principle…

The Command Query Responsibility Separation(CQRS) and Event Sourcing (ES) patterns advocate the building of applications by treating it as a System of Events plus State rather than just as a System of State.
