Channel 9

IoT Plug and Play is now in public preview (https://aka.ms/IoTShow/IoTpnp). In this episode you will see the new Azure IoT Central experience with native support for IoT Plug and Play. Azure IoT Central has drastically simplified the task of building IoT solutions by eliminating the need for any cloud side development. With IoT Plug and Play solution builders can explore a range of Azure IoT Certified Plug and Play devices; pick the devices that best fit their solution needs and build a production grade solution within days without having to write a single line of embedded code, drastically cutting down the time to market and costs.

In this session we show how to use the Blockchain Developer extension for VS Code to generate Logic Apps and Flows to publish ledger events to a DB. For more information head over to: https://aka.ms/bcvscode Follow @CH9 Follow @MSFTBlockchain

Saurya Das joins Scott Hanselman to show how multiple node pools for Azure Kubernetes Service (AKS) enable you to use different virtual machine sizes in a node pool supporting a variety of workloads in a single AKS cluster. For example, an e-commerce website can have a node pool for a billing service and another for a machine learning-based recommendation service, each with GPUs.

Jacob Jedryszek joins Scott Hanselman to talk about about using Cognitive Services with Azure Search with your mobile and web apps. Skip hiring search experts who know what an inverted index is. Don't worry about distributed systems expertise to scale your service to handle large amount of data. And forget about setting up, owning and managing the infrastructure. Let Azure Search do it all for you.

When a live site issue or outage occurs, quickly determining the root cause is critical. Standard monitoring solutions might alert you to a problem. They might even indicate which component is failing. But this alert won't always immediately explain the failure's cause. You know your site worked five minutes ago, and now it's broken. What changed in the last five minutes? This is the question that Application Change Analysis is designed to answer in Azure Monitor.
