Most applications don’t fail because of code — they fail because of infrastructure. In this video, I explain how modern DevOps practices evolved from manual server management to fully automated, self-healing systems using Infrastructure as Code (IaC) and GitOps. I also demonstrate a real-world cloud-native DevOps system that I built using Terraform, Kubernetes (k3s), and ArgoCD. 🔹 What you will learn: • Evolution of infrastructure (Manual → Cloud → Containers → IaC → GitOps) • What Infrastructure as Code (Terraform) solves • What GitOps is and how ArgoCD works • Push vs Pull deployment model • How modern DevOps systems are designed 🔹 Project Implementation: • 3-repository architecture (App, Infra, Kubernetes) • Dual pipelines (Application CI + Infrastructure pipeline) • Terraform provisioning on AWS (VPC, EC2, IAM) • Modular & variable-based infrastructure design • Security best practices (Private subnets, Security Groups, NAT Gateway) • Secrets management using AWS Secrets Manager • Cost estimation using Infracost • Security scanning using tfsec • Kubernetes deployment with GitOps (ArgoCD) • End-to-end automated workflow 🔹 Key Takeaways: • CI/CD alone is not enough • GitOps ensures system consistency • Declarative systems are more reliable • Real challenge lies in system integration 📌 Project / Article: https://www.linkedin.com/posts/lakshit175_devops-terraform-gitops-ugcPost-7450455693549244416-HOn1?utm_source=share&utm_medium=member_desktop&rcm=ACoAADwtIK8B3VHRUCeJMudoSk8HQHcgmx30TUQ 🔗 Connect with me: https://www.linkedin.com/in/lakshit175/ https://github.com/Lukky175 #DevOps #Terraform #GitOps #Kubernetes #CloudComputing #AWS #ArgoCD #CI_CD
