At the end of the talk a developer with a little bit of native development experience could start implementing cool models like real-time image classification right away! More

Modern applications are multi-client/platform distributed applications powered by (micro) services. Once you have solved the identity problem, you will inevitably deal with the question “what is the user allowed to do?”. It is very tempting to blur the lines between identity, authorization and business logic – but this will lead to problems down the line. As part of our work for PolicyServer ( we have developed a reference architecture that brings together OpenID Connect, OAuth 2.0, tokens and claims in a healthy way that allows for future growth and separation of concerns. Come and learn how! More

Cosmos Database CRUD operations Data JSON documents NoSQL PowerShell

In this session, I will demonstrate the Bot Framework with a free version of... More

Most cloud providers have a Kubernetes Service (AKS on Azure, GKS on Google and EKS on Amazon). However, the abstraction for app development on the Kubernetes platform that supports application self-healing, scaling and so on may not be at the right level. Helm and Draft makes this a lot easier by providing a lightweight CI/CD and production-grade deployments. In this primarily demo-driven session, we will cover Kubernetes and deployments on Azure (and another cloud time permitting) with some simple examples. We will look at Helm and Draft and how they can simplify app development significantly, like app. Scaling, rollback, etc. Helm is a tool that streamlines installing and managing Kubernetes applications, like the apt/yum/homebrew for Kubernetes....

Azure Bulk Insert Data Open Rowset PaaS Offering PolyBase SQL Data Warehouse SQL database

Most companies are faced with the ever-growing big data problem. It is estimated that there will be 40 zettabytes of new data generated between 2012 to 2020. See the computer world article for details. Most of this data will be generated by sensors and machines. However, only a small portion of the data is available for users. How can IT professionals help business lines gather and process data from various sources? There have been two schools of thought on how to solve this problem. Schema on write is represented by the traditional relational database. Raw data is ingested by an extract, transform and load (ETL) process. The data is stored in tables that enforce integrity and allow for quick retrieval. Only a small portion of the total... More

With the release of SharePoint feature pack two, integrating react into SharePoint went from painful to pain free. Nonetheless, not everyone has had the opportunity to upgrade. Understanding how to set up a (relatively) modern development toolchain & pipeline in Share Point is a helpful exercise is integrating various technologies together. We will walk through examples in SharePoint 2016 without SPFx and then contrast them with the new tooling available through SPFx. More
