The world becomes a virtual reality and things like bots are gaining more and more popularity. Organizations start to use them to intelligently transform business processes such as customer services, helpdesks and information retrieval. We will learn how we can leverage our existing skills in Azure to build intelligent creatures. We'll see how we can create a unique mix of services and frameworks like Microsoft Bot Framework, Azure Functions, Azure App Service, Node.js, Language Understanding Intelligent Service(LUIS) and Cognitive Services to accomplish our goals. The session shows at a glance the different integration options with services such as Skype, Microsoft Teams, Slack, Messenger and many others.
