Infrastructure as Code with Terraform

Managing cloud infrastructure manually is error-prone and doesn’t scale. Terraform lets you define your infrastructure in code, making it reproducible and auditable.

Why Terraform?

  • Provider agnostic — Works with AWS, Azure, GCP, and hundreds of other providers
  • Declarative — You describe what you want, Terraform figures out how to get there
  • State management — Tracks your infrastructure and plans changes before applying
  • Modular — Build reusable components

A Simple Example

resource "kubernetes_namespace" "app" {
  metadata {
    name = "my-application"
    labels = {
      managed-by = "terraform"
    }
  }
}

resource "kubernetes_deployment" "app" {
  metadata {
    name      = "my-app"
    namespace = kubernetes_namespace.app.metadata[0].name
  }

  spec {
    replicas = 3

    selector {
      match_labels = {
        app = "my-app"
      }
    }

    template {
      metadata {
        labels = {
          app = "my-app"
        }
      }

      spec {
        container {
          name  = "app"
          image = "my-app:latest"
        }
      }
    }
  }
}

Best Practices

  1. Use remote state — Store state in a shared backend (S3, GCS, etc.)
  2. Lock your state — Prevent concurrent modifications
  3. Use modules — Don’t repeat yourself
  4. Plan before apply — Always review terraform plan output
  5. Version pin providers — Avoid unexpected changes

GitOps with FluxCD: Declarative Deployments Done Right

GitOps is a paradigm where your Git repository is the single source of truth for your infrastructure and application state. FluxCD makes this practical.

What is GitOps?

GitOps applies DevOps best practices to infrastructure:

  1. Declarative — Your desired state is described in Git
  2. Versioned — Every change is tracked via Git history
  3. Automated — Changes are automatically applied
  4. Self-healing — Drift is detected and corrected

Getting Started with Kubernetes: A Practical Guide

Kubernetes has become the de facto standard for container orchestration. In this guide, we’ll walk you through the key concepts and get you up and running.

Why Kubernetes?

If you’re running containerized applications in production, you need orchestration. Kubernetes gives you:
