Observability as Code with Terraform
A technical how-to advocating "Observability as Code": storing dashboards, alerts, and SLOs in Git and managing them with Terraform. The article explains benefits (clear ownership, auto-updates, drift detection, PR review for alerts), provides provider examples (Datadog, Grafana, Prometheus, New Relic), shows Terraform code and a reusable module that generates dashboards, alerts, SLOs, Slack bindings and a PagerDuty policy, and proposes a practical migration timeline (week-by-week, then months). The author highlights human and process challenges (migrating click-ops dashboards, changing engineer habits, blocking UI edits) and warns against over-engineering dashboard modules.
Practical guidance on managing observability artifacts with infrastructure-as-code (Terraform) helps engineering teams reduce configuration drift and improve reliability, but it is a best-practice article rather than a major platform policy or product release.

Key Takeaways & Evidence Grounding
- Author recommends storing every dashboard, alert, and SLO definition in Git and managing them with Terraform alongside service code.
- Tooling examples list Datadog, Grafana, Prometheus (YAML + ArgoCD), and New Relic as provider approaches for observability-as-code.
- Example module call claims to create: 3 dashboards, 8 alerts, 2 SLOs, a Slack channel binding, and a PagerDuty escalation policy for a service.
- Benefits called out include clear ownership via CODEOWNERS, automatic updates through Terraform refactors, drift detection via terraform plan, and PR review for alert changes.
- A suggested migration strategy: convert one service in week 1, add alerts/SLOs week 2, delete UI versions week 3, create module week 4, roll out to 10 services by month 2, require module for new services by month 3.

Untangling 47,000 Lines of Terraform Without Downtime
A DevOps engineer inherited a 47,000-line Terraform monolith with a single state file and numerous operational hazards. The post documents a pragmatic, low-risk refactor: visualise dependencies, perform targeted state surgery with terraform state mv, split the state into domain-layer files (foundation, security, data, compute, edge), and wire components via terraform_remote_state. It also covers incremental modularization using a Strangler Fig pattern, hardening CI/CD (plan-on-PR, plan artifacts, manual production approval), removing secrets from code/state via AWS Secrets Manager and encrypted S3 backends, and implementing scheduled drift detection. The author provides a 12-week playbook (triage, split, modularize, harden) and concrete examples that reduced terraform plan time from 14 minutes to 45 seconds while avoiding downtime.
Monitoring & Observability Primer: Prometheus and Grafana
An educational technical article introducing observability for cloud-native systems. It explains why observability matters as infrastructure becomes distributed, defines the three pillars (metrics, logs, traces), and describes why metrics are typically implemented first. The piece presents Prometheus (an open-source, CNCF-maintained monitoring and alerting system originally from SoundCloud) and Grafana (visualization platform) as a common monitoring stack, outlines Prometheus components (server, exporters, Alertmanager, time-series storage), and gives step-by-step development and Kubernetes deployment examples (Docker run commands, Helm install kube-prometheus-stack). The article also surveys common monitoring, logging, and tracing tools and previews a Part Two focused on logging and tracing technologies.
Terraform & CloudFormation: An IaC How‑To Journey
A first‑person technical walkthrough explaining why and how the author moved from manual console clicks to Infrastructure as Code (IaC) using Terraform and AWS CloudFormation. The article compares Terraform (cloud‑agnostic, HCL-based) and CloudFormation (AWS‑native, JSON/YAML), shows example implementations for provisioning an S3 static website (with recommended practices), and lists common pitfalls and fixes — e.g., avoiding hardcoded credentials, preferring bucket policies over ACLs, using remote state with locking for Terraform, and reviewing CloudFormation change sets. The author frames IaC benefits as reproducibility, version control, teamwork safety, and faster onboarding, and provides concrete code examples and operational best practices.
