GitOps with ArgoCD: How the Reconciliation Loop Actually Decides to Sync
ArgoCD showed up as one piece of the best-of-breed stack I wrote about replacing an all-in-one platform with, without ever explaining what it’s actually doing
Autoscaling Beyond CPU: Custom Metrics, Queue Depth, and Predictive Scaling
I’ve written before about what adding more instances doesn’t actually fix — this is the narrower question of what should trigger adding them in the
Choosing Between REST, gRPC, and Event-Driven APIs for Service Communication
Picking service boundaries is one problem — I’ve covered that separately when writing about bounded contexts and communication between services. What actually crosses those boundaries
Designing a CI Pipeline for Monorepos: Caching, Affected Projects, and Build Times
Building a CI/CD pipeline from commit to production is one problem for a single project. A monorepo’s CI pipeline usually starts out simple the same
Terraform State Files Explained: Locking, Drift, and What’s Actually in Them
The .tfstate file is the part of Terraform that gets glossed over in most getting-started guides, right up until it’s the reason a deploy breaks
Structured Logging Done Right: JSON Logs, Correlation IDs, and the Fields That Matter
I touched on structured logs briefly while writing about Node.js observability in production, as one ingredient among several. It deserves its own post, because “Add
Idempotent Bash: Writing Scripts You Can Safely Run Twice
I’ve written about what bash setup scripts turn into once they grow up into real automation, and about a self-healing script I actually run —
The Strangler Fig Pattern: Migrating a Legacy System Without a Big-Bang Rewrite
I’ve written a monolith-to-microservices playbook before that mostly stayed at the level of architecture decisions — bounded contexts, service boundaries, the stuff of diagrams. The
Ansible Idempotency in Practice: What -vvv Actually Shows You
I’ve written before about Ansible as part of a broader IaC toolchain without ever digging into this specific property on its own — worth fixing
