SDN event March 2017

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.

Customer identities in an Enterprise scenario

With slides and demo’s Jurgen showed us the Azure Active Directory Business 2 Consumer (AD B2C) solution from Microsoft. It differs from AD that you don’t know how many users you need in advanced and thus the costs are mainly based on the number of authentications, where AD charges for the amount of users.

The features include self-service (password reset, signup, …), usage of (social) identity providers and extensive login page customisation.

Zero-downtime applications with containers

Docker is used for highly available solutions. In the demo a docker swarm was used to host a .net core application. With a visualizer container the setup (1 master and 2 slaves) was visualised on a website.

Using blue-green / rollout scenario’s the upgrade can be performed. Tips for database scheme: support version n-1 and do an upgrade after the last n-1 version of your application is replaced.

Fun fact: presentation had to be done with webcam from laptop #1 pointed to screen of laptop #2 because the projector couldn’t handle the resolution of laptop #2. 😎

Progressive web apps and the future of the web

Progressive web apps (PWA) are defined as Reliable (offline), Fast (install/usage) and Engaging (capabilities). It uses a Service worker, which is installed from the website. The Service Worker reacts to events, retrieves data from the internet when online or from the cache when offline.
Interesting links for PWA:

The presentation was recorded and is available on youtube:

Conclusion

A lot is happening and a single developer can’t keep up with all new things. This SDN event is (again) a great way to see what’s happening and get first hand information from experts.

About erictummers

My work as a recruited developer changes almost every month. I like challenges and sharing the solutions with others. On my blog I’ll mostly post about my work, but expect an occasional home project, productivity tip and tooling review.
