PoC of the distributed request telemetry

Dependencies

.NET 6

You can install it from https://dotnet.microsoft.com/en-us/download

Azure services

To increase the amount of data that OpenTelemetry can run collect and present, the repository uses a few Azure dependencies:

• ServiceBus - to send calculation requests from WebService to the Worker
• Table Storage - to store the result for given N
• SQL Database and Entity Framework - to store information about the caller of the POST /n endpoint. It doesnt bring any additional value and it was added only to generate extra traffic to external dependency.

You need to create these services and update configuration in the appsettings.json in both project, or create appsettings.local.json file with only these values to override empty strings.
