 NOTE: For testing, you can use alternatives to Nginx such as https://learn.microsoft.com/en-us/azure/developer/dev-tunnels/overview[Azure Dev Tunnels] or https://ngrok.com/[Ngrok], but using Nginx makes it easy to collect additional telemetry and monitor its status by using Elastic's native Nginx integration. While this example uses cloud infrastructure, it could also be replicated locally without an internet connection.
