You've learned how to deploy a web application built with Angular 8 and ASP.NET Core 3.0 on Microsoft Azure, leveraging Twilio Programmable Video for robust video chat functionality. You can host your app in a fully managed enterprise-grade cloud platform, deploy configuration settings securely, and take advantage of continuous deployment features provided by Visual Studio and Azure. The process involves publishing the code from Visual Studio, adding Twilio configuration credentials to Azure through the Azure Portal, and configuring the app for production use. After publishing, you can test your video chat application functionality in a browser, allowing users to join rooms and engage in live video conversations.
