Study Notes

Log Alert Rule

Azure Function App

  • Custom handlers can be used to create functions in any language or runtime by running an HTTP server process, for example Go or Rust.
  • Triggers are used to invoke functions and can have exactly one trigger.
  • Bindings provide a declarative way to connect data to your code.
  • Azure Storage events allow applications to react to events.
  • Storage (general purpose v1) does not support integration with Event Grid.

Azure Web App

  • TLS mutual authentication can be configured for the web app.
  • Client certificate can be accessed through the HttpRequest.ClientCertificate property in ASP.NET.
  • Client cert can be available through a base64 encoded value in the "X-ARR-ClientCert" request header.
  • Create a system-assigned managed identity for the application.
  • Create an access policy in Key Vault for the application identity.

Website Deployment

  • Deploy the website to an App Service that uses the Standard service tier.
  • Configure the App Service plan to automatically scale when the CPU load is high.

API Management

  • Basic gateway credentials can be used to secure access to the back-end service of an API.
  • Client cert gateway credentials cannot be used for Azure resource.
  • API back end is hosted in an Azure App Service instance, which is an Azure resource and not an HTTP(s) endpoint.

Deployment Slots

  • Auto swap can be enabled on the Production deployment slot.
  • Update the web.config file to include the applicationInitialization configuration element to specify custom initialization actions.
  • The swap operation waits for this custom warm-up to finish before swapping with the target slot.
