Tags web-development app-development cicd devops how-to

The article details a two-part CI/CD Pipeline Architecture Framework designed to guide teams from basic automation to a mature development platform. The first part, the “Golden Path,” is a linear, six-stage workflow that forms the essential, reliable backbone: Code Commit (with branching strategy), Automated Build (ensuring environment parity), Automated Testing (using a test pyramid), Staging Deployment (mirroring production via IaC), Production Deployment (with health checks and rollback), and Monitoring & Feedback (closing the loop with observability). By Kamil Chmielewski.

What you will learn:

  • A robust CI/CD pipeline requires both a reliable core workflow (“Golden Path”) and strategic enhancements (“Pipeline Pillars”).
  • The Golden Path’s six stages (Commit, Build, Test, Stage, Deploy, Monitor) must be automated, repeatable, and provide fast feedback.
  • The seven Pipeline Pillars (e.g., Feature Flags, Advanced Testing, Security) are modular capabilities that address specific scaling and operational challenges.
  • Implementation is progressive: master the foundational Golden Path first, then selectively adopt pillars based on team needs.
  • Pipeline success should be measured using developer experience metrics and business outcomes (e.g., deployment frequency, lead time).
  • The CI/CD pipeline should be treated as an internal product, with developers as the primary customers.
  • Practical checklists are provided for each Golden Path step and Pipeline Pillar to guide implementation.
  • The framework aims to create a platform that enables high-velocity, reliable software delivery without sacrificing security or developer productivity.

This article provides exceptional value as a comprehensive, structured guide. It successfully synthesizes established DevOps principles into a clear, actionable framework. While not introducing novel concepts, its significant contribution is the practical “Golden Path + Pillars” model and accompanying checklists, which offer teams a clear roadmap for incremental maturity. It represents a highly effective compilation of best practices for platform engineering. Great read!

How to find and remove unused Azure Data Factory Pipelines

Categories

Tags web-development app-development devops azure big-data

A 20-line PowerShell snippet scans every subscription, flags ADF factories that haven’t executed a pipeline in 30 days, and hands you a clean-up hit-list in seconds. By Dieter Gobeyn.

This blog post provides overview of:

  • Zero-run ADF factories still accrue IR, logging, and governance costs.
  • “Unused” = no pipeline execution in last 30 days (configurable).
  • One self-contained PowerShell script; read-only, no extra modules.
  • Iterates all subscriptions, outputs table with subscription, RG, name, tags.
  • Safe for Reader roles; can be scheduled in Azure Automation.
  • Extend script to pipeline-level or different time windows as needed.
  • Clean-up decisions remain manual—pair output with tagging/owner process.

Stale ADF pipelines bloat your tenant: they burn IR capacity, inflate log ingestion, confuse engineers, and widen the blast-radius of a security breach. Gobeyn’s post supplies a single, self-contained PowerShell script that enumerates every subscription, queries the ADF activity log for runs in the last 30 days, and returns a table of “zero-run” factories together with resource-group, subscription, and tags. Run it, eyeball the list, delete or disable—no external tools, no cost, no excuses. Perfect for FinOps squads, SREs, and data-platform owners who need a quick hygiene win before the next funding review. Nice one!
