For more information about autoscaling, see Autoscaling best practices.įor other scalability topics, see the Azure Architecture Center Performance efficiency checklist. As a result, you can use the standard App Service autoscaling features to automatically scale the number of instances running your bot, which allows your bot to keep up with demand. The bots used in this scenario are hosted on Azure App Service. Bots can send a message when something has changed in a document or a work item is closed.Īlthough monitoring isn't implemented in this example scenario, a bot's app service can utilize Azure Monitor services to monitor its availability and performance. By helping anticipate possible next steps, bots make it much easier for people to a complete task flow. Bots can deliver an exact match to a query or a group of related matches to help with disambiguation. Organizations can utilize bots for mobile and desktop users. This means that all traffic that goes to a bot, and responses from the bot, must route through a corporate firewall, as with any other web app. InfoSec policy commonly requires that all incoming traffic to web apps go through a corporate firewall. One of the key requirements for the bot to work is that it must expose a publicly accessible HTTPS endpoint. A key component of a bot is the web app, which contains the core logic and interface that users communicate with. After they're developed, you can deploy them to Azure. You can develop bots by using a variety of languages, such as C#, JavaScript, and Python. The Microsoft Bot Framework and Azure Bot Services give you an easy-to-use set of tools for creating and managing these bots. This example doesn't make use of an App Service Environment to reduce costs, but the sample architecture could support it, with modifications.īots allow Teams users to interact with web services through text, interactive cards, and task modules.

An App Service Environment can provide a fully isolated and dedicated environment for securely running App Service apps at high scale.

Virtual network integration connects the app service to the virtual network, ensuring that outbound traffic from the bot app service passes through the firewall. This way, the app service can be accessed only through the firewall.Īzure Private Link service for inbound access to the bot app service over an Azure private endpoint.

The app service has a registered custom domain that points to the IP address of the firewall.

The Virtual Network Integration Subnet and the Private Endpoint Subnet are associated with the route table, ensuring that any traffic passing through them is routed through the firewall.īot Service consists of the bot app service plan, app service, and bot channels registration. The default route with the 0.0.0.0/0 address prefix instructs Azure to route traffic that isn't within the address prefix of any other route to the subnet where the Azure Firewall instance is deployed. It ensures that traffic coming to and from the bot passes through the firewall. Route table defines the routes that traffic takes within the virtual network. The Azure Firewall instance is placed in its own subnet. Ordinarily, a firewall is placed in its own virtual network, which is a common pattern for hub and spoke architectures, but this simplified example deploys all services and resources into a single virtual network. Private Endpoint Subnet (10.0.3.0/24), which is used to route traffic from the firewall to the bot's private endpoint.Īzure Firewall exposes a single public IP address that clients can use to communicate with the underlying bot services. Virtual Network Integration Subnet (10.0.2.0/24), which is used to route traffic from the bot's private endpoint to the firewall.

The virtual network in this example uses the address space of 10.0.0.0/16, and contains three subnets for use by the scenario's required components: DataflowĪzure Virtual Network enables communications between Azure resources. Architectureĭownload a Visio file of this architecture. At the same time, it enables channels in the Teams client to communicate with the bot through an IP that's exposed through an Azure Firewall instance. This example scenario helps secure the connection to a Microsoft Teams channel bot's web app by using Azure Private Link and Azure Private Endpoint.
