This bot is created using azure services. Here, we will create an echo bot using the Azure Bot Service and test in web chat.
A bot is an app that users interact with in a conversational way, using text, graphics (such as cards or images), or speech. Every interaction between the user and the bot generates an activity. The Bot Framework Service, which is a component of the Azure Bot Service, sends information between the user's bot-connected app (such as Facebook, Skype, etc. which we call the channel) and the bot.
An App Service plan defines a set of compute resources for a web app to run. These compute resources are analogous to the server farm in conventional web hosting.
