Create an environment for deploying and developing applications using Terraform and Kubernetes with Infrastructure as Code (IaC) principles on Hetzner Cloud. Create a suitable design that will ensure the application's high availability. Establish automated staged application deployment using a continuous delivery pipeline utilizing ArgoCD. Use self-healing infrastructure for applications with health checks, automatic failover, and restarts. Create appropriate automated scaling. Implement monitoring solutions to allow real-time system observability and logging. Discuss possible security concerns in implemented IaaC. Employ automated tools to analyze infrastructure to detect vulnerabilities and miscofigurations as part of a CI pipeline.
