Requirements

The application components must meet the following requirements:

Corporate website

• The site must be migrated to Azure App Service.

• Costs must be minimized when hosting in Azure.

• Applications must automatically scale independent of the compute resources.

• All code changes must be validated by internal staff before release to production.

• File transfer speeds must improve, and webpage-load performance must increase.

• All site settings must be centrally stored, secured without using secrets, and encrypted at rest and in transit.

• A queue-based load leveling pattern must be implemented by using Azure Service Bus queues to support high volumes of website agricultural production resource requests.

Farms

• Farmers must authenticate to applications by using Microsoft Entra ID.

Distributors

• The company must track a custom telemetry value with each API call and monitor performance of all APIs.

• API telemetry values must be charted to evaluate variations and trends for resource data.

Internal staff

• App and API updates must be validated before release to production.

• Staff must be able to select a link to direct them back to the production app when validating an app or API update.

• Staff profile photos and email must be displayed on the website once they authenticate to applications by using their Microsoft Entra ID.
