Data is the buzzword these days: organizations want to be data driven. They create a lot of data, want to create value out of this data and want the data fast and available 24/7. Therefore the IT architecture needs to be flexible, scalable, resilient, responsive and message (data) driven.
This is where an Event Driven Architecture (EDA) can help and in the next 4 blogs I want to guide you in this event journey.
This first blog will be about events in general and how they can be utilized on all kinds of levels within an organization. In the second blog I will talk about a reference architecture that organizations can use as a starting point. It explains which capabilities are relevant in such an architecture. In the third blog I will describe some principles and guidelines that you can use within an event driven architecture. In the last blog I will explain how an organization can become event driven. I will take you through a maturity model and the steps that you can take to get to a level that your organization needs to reach its business goals.
One of my hobbies is photography and when I bought my first camera it was a compact camera. I soon realized and experienced that I needed a reflex camera (SLR), because the resolution, speed and quality was far more better. I did not realize it until I really used the product. The again after a few years I noticed that I did not use my camera a lot. Why was that? Because the camera was pretty big and unpractical to take with me all the time. Then I read about a system camera, which has the advantage of being small, but still has the possibility to switch lenses. I never regretted my choices, because at the time it seemed to be the best choice. Today there are a lot of camera’s with lots of possibilities and specifications. Which one to pick? This depends on a lot of factors. What do you want to photograph with the camera. What type of photographs do you want to take, for example portret-, landscape-, sport- or street photography.

Op 15 november 2018 hebben we met SynTouch het Landelijk Architectuur Congres bezocht in de Brabanthallen in Den Bosch. Dit jaar was het thema “Paradoxen in Architectuur”. En dit jaar konden we een feestje vieren, want het LAC bestaat 20 jaar !
Normaal gesproken is het beeld van een architect saai, oubollig en werken vanuit een ivoren toren. Kijken of hier langzaam verandering in gaat komen en zelfs sexy gaat worden. Of blijkt dit toch nog steeds een paradox?

Event Driven Architecture helps with decoupling applications
Think about the names used for events
Let Publisher publish and filter within subscribers
Use meta data within event headers
Use standardization on entities within Event, so that the Event is a first citizen data object
There is a lot of hype around Microservices and the use of events for implementing the choreography pattern. However this is nice for companies like Netflix and Twitter, but there are a lot of organisations still struggling with files and ESB like products. Also my current client uses an ESB namely the Oracle SOA Suite 12c for integrations. We cannot just throw away this ESB, but we can make use of the event mechanism built in. This blog describes the way we use the EDN (Event Delivery Network) component, that is used within SOA composites to throw events and to subscribe on events.

A lot of applications have integration possibilities, so do cloud applications. The question I got from a customer is whether to have a point-to-point integration with Cloud applications or to go through their ESB solution. This blog describes some considerations.
On the 22 and 23rd of March I went to the ‘Microservices Conference 2018, MicroXchg’ in Berlin. This blog post is a short recap of my experience of this conference, this year held for the 4th time.
My goal was to learn more about the Microservices world, to fill my toolset of possible architecture solutions and of course to see Berlin a bit. Furthermore, I interviewed Chris Richardson about Microservices and his upcoming book on Patterns. This interview is added to this blog as well.

Veel productiebedrijven met productielocaties waar de producten daadwerkelijk gemaakt worden, hebben moeite om de business-systemen aan te sluiten op de productievloer-systemen. Op kantoor worden sales orders ontvangen. Deze worden doorgestuurd naar de planningsafdeling. En uiteindelijk worden de productieorders verstuurd naar de productievloer. Deze supplychain omvat dan plan-source-make-deliver.

Testability is one of the underestimated qualities of software. This is also the case for WSO2 ESB projects. However, it is important to design the integrations for testability. This starts with the way you setup the proxies. This blog gives some guidelines which you can use to design for testability.
