The SDN – Software Development Network – is a special interest group for dutch developers. Four times a year they organise an event where people present and talk about their passion.
As a member of the SDN you are aware of the latest developments. You are part of a network of professional developers who assist each other in word and deed. This means there is a technical helpdesk at your fingertips so you can book considerable time savings in solving problems.

Here are the talks I attended.
The Things Network
The things network offers a solution for IoT network communication. In the demo / presentation an arduino is used to send an alert when “the machine” has stopped. The alert is send over the things network to azure and a return message resets “the machine”.
Communication path: board > gateway > the things network > azure webjob (bridge) > IoT hub > stream analytics > Event hub > azure function (sends the reset) > IoT Hub > bridge > the things network > gateway > board > led turns on 🙂
Design your system for Black Friday
Make use of the infrastructure like reverse proxy, caching and message queues. Optimise for read or write, use less layers and do proactive monitoring.
Continuous delivery in practice
All developers at snelstart (50) use the same branch. Every checkin can potentially go to production. With toggles features can be enabled or disabled for certain customers.
Every environment (OTAP) must be the same. Same platform, same amount of data. This way deployment to production will not introduce new problems.
Because of the speed the build, deployment and tests are automated. Tooling used is Azure, TFS, Octopus deploy and some test automation tools. Every checkin triggers a build and then a release and tests. When build / deployment / test fails the process is abandoned. A new checkin must be done to fix the problem.
This talk was mainly about nservicebus and the domain driven architecture. Nice to know there are dutch people working at Particular today.
