SLOs and Error Budgets: Turning Uptime Into a Number You Can Act On
Finding and fixing a bottleneck — the practical framework I wrote about earlier — answers “why is this slow.” SLOs answer a different question: how
Multi-Region Architecture Without the Complexity Tax: What You Actually Need
Platform engineering and FinOps conversations — the shift I wrote about here — eventually run into this exact question from the cost side. “We should
Secrets Management for Infrastructure as Code: SOPS vs. Vault vs. Kubernetes Secrets
Every “Infrastructure as Code” pitch runs into the same awkward question eventually: if everything is code, checked into git, reviewed and versioned — where does
Kubernetes Health Checks: Liveness, Readiness, and Startup Probes Explained
Understanding how the control plane actually schedules and tracks pods explains what a probe result feeds into. The three Kubernetes probe types get explained by
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

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
