Azure Bot Service offers two Bot creation/hosting offerings you can choose from (Web App Bot and Functions Bot) and the Bot Channels Registration offering that enables you to host your bot wherever you like.

Apart from the above pricing, you also pay for resources consumed as described below.

For the Bot creation plans, your bot will be powered by Azure App Services and follows the App Services pricing model.

  • For a Functions Bot, the Azure Bot Service will run on Azure Functions in consumption mode.
  • For a Web App Bot, the Azure Bot Service will run as standard Azure Web App.
  • For a Bot Channels Registration, no App service will be provisioned.

As a part of creating your bot, Azure Bot Service will optionally provision an instance of Application Insights using the Basic tier and will appear in your Azure subscription. Azure Bot Service will then be configured to send diagnostic events and other telemetry for your bot and is used to power the analytics page. Learn more about Bot Service analytics.

During bot creation, you will choose an Azure Bot Service template most appropriate for your scenario. Depending on which template you use for your Bot, Azure Bot Service may need to provision an instance of the Cognitive Service Language Understanding Intelligent Service (LUIS) or QnA Maker. Both are created using free or trial tiers and will appear in your Azure subscription.

FAQ

  • Bots communicate with the Bot Service channels by sending Activity objects to the channel endpoint via HTTP POST and by Activity objects being sent to the Bot’s endpoint via HTTP POST. Each of these Activity POSTs is a message.

  • The Bot Service provides protocols and API’s through which you can connect your Bot to the services where your customers are. A channel represents the service you wish to reach your users on, such as Skype, Microsoft Teams or Facebook.

  • Standard channels include Microsoft first-party services (such as Skype, Cortana and Microsoft Teams) and services with publicly available Bot API’s (such as Facebook and Slack). Please refer to the Bot Service documentation for the complete list.

  • The premium channels allow your bot to reliably communicate with users within your own application or on your website. These channels allow you to customise the client experience for your users by customising the open source DirectLine and Web Chat clients. Please refer to the Bot Service documentation for details.
