Kubernetes Migration from Compose: Where the Five-Service Ceiling Collapses and Latency Demands Force an Early Exit
ByTheo Brandt October 20, 2026

Container orchestration decisions made too early waste engineering hours; decisions made too late force emergency rewrites under production load. Docker Compose remains the standard starting point for multi-container applications, but its structural limits appear predictably as service counts grow. This article maps the documented inflection pattern where Compose file complexity, network mesh overhead, and latency…

Wiring Distributed Tracing from Microservices to Mainframe COBOL Batch Jobs
ByTheo Brandt October 16, 2026

Distributed tracing across the microservices-to-mainframe boundary requires bridging two fundamentally different execution models: synchronous HTTP request-response cycles and asynchronous batch job processing with no inherent caller-callee relationship. This article maps an executable path using OpenTelemetry as the unifying telemetry layer, with version-anchored configuration for each integration point. The Core Problem: Two Worlds, One Trace ID…

Your CI Pipeline Needs the Postman CLI but Your Developers Want Bruno
ByTheo Brandt October 16, 2026

API testing tools sit at the intersection of developer productivity and pipeline reliability. Two command-line options dominate the 2025-2026 landscape: the Postman CLI, backed by a mature platform ecosystem, and Bruno, a git-native open-source client gaining traction among developers who prioritize local-first workflows. This article maps the technical differences, conversion paths, and CI integration patterns…

The Hidden Rollback Cost When Terraform Cloud State Grows Past the Managed-Resource Threshold
ByTheo Brandt October 16, 2026

Infrastructure as code pricing looks predictable at small scale. A per-resource rate, multiplied by resource count, multiplied by time. But Terraform Cloud’s hourly peak-managed-resources billing model introduces a compounding effect that only becomes visible once state files grow—and the cost of reversing course rises in lockstep. This article maps the billing mechanics across Terraform Cloud’s…

EKS vs AKS vs GKE: Picking Managed Kubernetes by Cloud Footprint and Data Transfer Costs
ByTheo Brandt October 14, 2026

Choosing between Amazon EKS, Azure AKS, and Google GKE starts with understanding where each platform hides its costs. The control-plane fee is the headline everyone compares, but for most workloads, data transfer—especially cross-zone traffic—drives the larger share of the bill. This managed Kubernetes comparison breaks down the published pricing structures, flags where documentation conflicts, and…

Migrating from .env Files to a Secrets Manager Without Breaking Local Development
ByTheo Brandt October 14, 2026

.env files are the default starting point for most development teams. A single file, a handful of KEY=value lines, and your application boots. At small scale, this works. At team scale, it fails systematically: credentials leak into version control, rotation requires manual coordination across every developer’s machine, and no audit trail exists to show who…
