Practical articles on Terraform, AWS architecture, infrastructure visualization, and DevOps workflows.
How AWS IAM actually works — principals, policy types (identity-based, resource-based, SCPs, permission boundaries), evaluation order, trust policies, Terraform patterns for instance profiles and IRSA, and how to debug access denied errors.
Read more →How Docker networking works across all four network drivers — bridge vs host vs overlay vs macvlan. Covers user-defined networks, the embedded DNS resolver at 127.0.0.11, port publishing iptables mechanics, Compose multi-network isolation, and debugging tools.
Read more →The difference between resource requests (scheduling guarantee) and limits (runtime ceiling), why CPU throttles but memory OOM-kills, how QoS classes (Guaranteed/Burstable/BestEffort) affect eviction order, and how to set LimitRange, ResourceQuota, HPA, and VPA.
Read more →The four OpenGitOps principles, pull-based vs push-based model, app repo vs config repo pattern, ArgoCD's Application CRD and app-of-apps pattern, Flux's GitRepository/Kustomization/HelmRelease CRDs, and an honest comparison of when GitOps helps vs adds friction.
Read more →How to write a well-structured Terraform module (main.tf/variables.tf/outputs.tf/versions.tf), when to extract a module vs keep code flat, version pinning with ~> X.Y, Terratest Go testing, the built-in terraform test framework (1.6+), and generating docs with terraform-docs.
Read more →How Kubernetes networking actually works at each layer — from the flat pod network guarantee to ClusterIP/NodePort/LoadBalancer services, Ingress controllers, and NetworkPolicy rules. Includes debugging steps for the most common failures.
Read more →An honest comparison of the three dominant IaC approaches. Covers deployment engine differences, state management, abstraction models, multi-cloud support, and which tool fits which team situation — including hybrid approaches.
Read more →Everything you need to know about Terraform state — the state file format, remote backends, locking, drift detection, importing existing resources, workspaces, and recovering from corruption or accidental deletion.
Read more →Stop switching context. Install the InfraSketch MCP server and ask your AI editor to diagram Terraform or Kubernetes code — it returns a shareable URL and embed snippet without leaving the editor.
Read more →Run npx infrasketch . in any IaC repo and get an interactive architecture diagram in the browser — no install, no copy-paste, no credentials. Works with Terraform, OpenTofu, Kubernetes, Pulumi, and more.
Read more →Add one script tag and drop <infra-sketch src="./main.tf"> anywhere on your docs, blog, or GitHub Pages site. The diagram loads live from a public IaC URL — no iframe boilerplate, no upload.
Read more →Add one step to your workflow and every Terraform, Kubernetes, or Bicep PR gets an architecture diagram comment automatically — free, no secrets needed, 2-minute setup.
Read more →How Checkov works, which CIS Benchmarks and security frameworks it covers, how to run it, how to interpret and remediate common findings (S3, EC2, RDS, IAM, Kubernetes), and how to integrate it into a CI/CD pipeline with GitHub Actions and SARIF output.
Read more →How Infracost estimates cloud costs from Terraform before you deploy, what it can and can't estimate, usage files for Lambda and DynamoDB, integrating cost diffs into pull requests with GitHub Actions, and common cost optimization patterns (NAT Gateway, right-sizing, gp3 storage).
Read more →Paste Terraform HCL and get an architecture diagram in seconds. AWS, GCP, and Azure resources auto-detected, grouped by layer, with official cloud icons. VPC containment, reference arrows, export to PNG/SVG/draw.io. Free, no login.
Read more →Paste Azure Bicep or ARM JSON templates and get an architecture diagram in seconds. VNet containment, subnet placement, 40+ Azure resource types with official icons. Free, no login.
Read more →Pulumi TypeScript and Python support with 95+ resource types across AWS, GCP, and Azure. Kubernetes YAML support with 16 resource kinds, namespace grouping, and selector-based connections.
Read article →Paste Pulumi TypeScript or Python code and get an architecture diagram in seconds. VPC containment, subnet grouping, multi-cloud (AWS, GCP, Azure). 95+ resource types. Free, no login.
Read more →Paste Kubernetes YAML manifests and get a topology diagram with namespace grouping, Ingress→Service connections, selector-based wiring, and ConfigMap/Secret references. Free, no login.
Read more →Run cdk synth, paste the JSON output, get a full architecture diagram. VPC containment, subnet lanes, official AWS icons. Free, no login.
Read more →Turn CloudFormation YAML or JSON into architecture diagrams in seconds. Supports !Ref, !GetAtt, VPC containment, subnet grouping, and 30+ AWS resource types. Free, no login.
Read more →Interactive drag-and-drop diagram editor with live connection updates, full GCP support across 23 resource types, four new AWS networking resources, data zone visualization, toast notifications, and a round of UI polish.
Read article →A practical comparison of every method for creating AWS architecture diagrams — from manual drawing tools to automated generators. Includes tool comparison, best practices, and when to use each approach.
Read article →Your Terraform codebase has grown to thousands of lines across dozens of files. But can you actually see what it builds? Here are five practical approaches to visualize Terraform infrastructure.
Read article →Cloudcraft costs $49/month. Draw.io is free. InfraSketch generates diagrams from code. Which one should you actually use? An honest comparison based on real-world usage.
Read article →Docker Compose files grow complex fast. Learn how to generate architecture diagrams from your docker-compose.yml to understand and document your container architecture.
Read article →A visual guide to AWS VPC architecture, from a single public subnet to a production-grade multi-AZ setup with private subnets, NAT gateways, and load balancers. Every pattern shown with Terraform code and diagrams.
