Microsoft yesterday announced the preview releases of two new Azure PaaS services for Azure Stack TP2. It includes Azure App Service (Web Apps, API apps, and Mobile apps) and updated versions of SQL/ MySQL database. After deployment, you can build web and mobile applications between Azure and Azure Stack, enabled by true hybrid cloud consistency.
Microsoft has also streamlined the deployment experience. You can download the bits here. If you have already deployed Azure Stack, you will need to redeploy TP2 using the updated bits above before deploying the Azure PaaS services.
