Over the last couple of years the engineering team at Mendix has grown fast. Over the last 1.5 years the team has almost doubled and we are still looking for bright minds. There is a lot that can and will go wrong if you grow this fast. Here are my four…

A couple of weeks ago we had Mendix World, our global community event. I really enjoyed the event! It was inspiring to talk with so many of our users, customers, and partners, and to just feel the vibe. If you missed it you can get a glimpse of the…

Platform-as-a-Service (PaaS) is hot! Why? Because the year started with a lot of link-bait articles declaring PaaS dead. That’s a clear sign, right? More seriously, the expected size of the public PaaS market will be $14 billion by 2017. That’s about 10…
OpenStack doesn't have business value itself. It needs additional services like PaaS or even better Model-Driven PaaS to become relevant for the business.

Platform-as-a-Service (PaaS) is all about abstraction and automation. Abstracting away from underlying technology layers by automation. That’s basically what is happening on each layer of a cloud architecture, from hardware to IaaS, to foundational PaaS,…

Software is eating the world! Every company is becoming a software company. If companies don’t, they cease to exist. Just imagine: you are a thermostat maker and suddenly you have Google as a competitor (via its Nest acquisition). This is just one of the…

Microservices definitely have relevance in this context. I didn't mention it because it basically is orthogonal on the architecture stack I sketched. However, approaching your architecture with these cloud layers in mind help a lot in enabling a microservices architecture.

In my opinion microservices are necessary to scale your app landscape without loosing autonomy (of teams and components) and adaptability.

"I work for a PaaS company" I answered him. "Ah, okay, great", and he moved to another subject. It was a cold winter day on a hipster cloud conference. He wasn't the only one that directly knew what my company did. Most people there knew the difference between Infrastructure-as-a-Service (IaaS), ...
