What is the role of the Zipped file during deployment with Microsoft Azure?

[Sneha Sabu]

script:
  - pipe: atlassian/azure-web-apps-deploy:0.2.1
    variables:
      APP_ID: $APP_ID
      PASSWORD: $PASSWORD
      TENANT_ID: $TENANT_ID
      RESOURCE_GROUP: $RESOURCE_GROUP
      NAME: 'my-site'
      ZIP_FILE: 'my-package.zip'

[Badr Eddine Zebbiche]

The role is compress the artifacts into one single zipped file for deployment.

A necessary step would be archiving the zip file itself using

script: 
  - echo "Archiving the artifacts" 
  - zip {APPL_NAME}.zip File1 File2 File3
