Build Stuff 2017

.NET developers today enjoy a bountiful source of platforms, tools at their disposal. With Xamarin they can target all the major mobile platforms and Azure providing cross cutting features for mobile developers and the necessary scale to support any degree of mobile clients.
In this session we will take Xamarin Forms, Azure App Services and SignalR to create a full blown Messenger app in just 60 minutes.

The buzz is all around Cloud Native: continuous deployment and easy scaling of your server side code. You have heard about Docker and Microservices, but what are 12-factor apps? The Twelve-Factor App methodology (https://12factor.net​/), was created by engineers with experience of delivering apps on Heroku, and is a "recipe for success" when authoring code for cloud native senarios.

In this presentation we will look at what a Twelve-Factor App is, and demonstrate how to meet the requirements when creating .NET applications. We will show examples using ASP.NET Core, Brighter and Darker of authoring code to meet these requirements, and show its deployment to containers using Docker.

By the end of this talk you will know enough to be able to approach another pillar of Cloud Native.

AWS Lambda has changed the way we deploy and run software, but this new serverless paradigm has created new challenges to old problems - how do you test a cloud-hosted function locally? How do you monitor them? What about logging and config management? And how do we start migrating from existing architectures?

In this talk Yan will discuss solutions to these challenges by drawing from real-world experience running Lambda in production and migrating from an existing monolithic architecture.

Cloud networking runs at seemingly improbable scale - millions of networks from different tenants flow, sometimes with tens of thousands of instances per network - all on the same physical substrate. Often the performance requirements are huge - expensive GPU-intensive compute jobs must be fed with data in order to keep them efficient. It is plainly clear that traditional networking technology is not behind this - so what is? In this talk we'll look at the building blocks of cloud networking - from hypervisors to switches - from first principles, show how the building blocks fit together, and how this maps onto various cloud network offerings.

The revolution of cloud computing has bootstrapped a transformation of harnessing IT as we know it. The power and potential of cloud computing has never been clearer. If you're resisting it because of security concerns, you risk being left behind, missing out on the most disruptive and innovative periods in technology so far. Emerging with cloud computing is a second revolutionizing philosophy. The one of DevOps and Continuous Delivery. In contrast to the old ways of ensuring that our software is available, stable and secure, we no longer have the time to let it block progress and speed. Security is not only failing to protect, it's also hindering the organization’s productivity. Because if security blocks progress and speed, it will be ignored and marginalized.

The last year we have migrated all customer facing applications from internal hosting to the cloud at Norwegian Railways (NSB). We have also created a handful of new services and split up many of the legacy ones. Our main focus has been to enable fast flow of features into production while preserving world-class availability, stability, and last but not least security. In this talk I will share with you our experiences and choices made along the way. Furthermore I will show you our tooling, technology choices and explain our process adaptations. Participants should have some experience with software development and/or administration of public cloud computing. There will be code. The audience should agree that security is important.
