Testing an Azure Function on a staged environment using deployment slots

In general, every application needs pre-production environments, such as staging, and beta, in order to review functionalities before publishing them for the end users.

Though the pre-production environments are great and help multiple stakeholders to validate the application's functionality against business requirements, there are some pain points in managing and maintaining them. The following are a few of them:

  • We would need to create and use a separate environment for our pre-production environments.
  • Once everything is reviewed in pre-production and the IT Ops team gets the go-ahead, there would be a bit of downtime in the production environment while deploying the code base of new functionalities.

All of the preceding limitations can be covered in Azure Functions, using a feature called slots...
