Case study

Cloud Delivery Platform

Standardized infrastructure and deployment workflows across cloud and on-prem environments.

Technologies
  • AWS
  • GCP
  • Terraform
  • GitLab CI
  • CI/CD
Focus areas
  • Reusable deployment pipelines
  • Infrastructure automation
  • Standardization
  • Developer enablement

Problem

Delivery patterns varied from project to project and environment to environment. Pipelines were implemented differently each time, CI/CD logic was repeated across repositories, and cloud and on-prem targets each needed their own deployment steps.

That made infrastructure changes harder to keep consistent and left more room for configuration drift and deployment mistakes. Teams needed DevOps support for patterns that should have been reusable, while deployments still had to stay reliable across different application requirements.

Approach

I focused on reusable building blocks rather than one rigid pipeline for every project. Shared CI/CD patterns standardized the common deployment stages, while leaving room for project-specific configuration where it was needed.

Reusable Terraform modules covered common infrastructure components, with every change version-controlled and repeatable. Platform logic was kept separate from application-specific configuration, so AWS, GCP and on-prem deployments could follow the same overall delivery model.

The aim was self-service: teams could use established patterns instead of needing custom DevOps work for every deployment, and the shared patterns kept evolving as more projects adopted them.

Architecture

Application and infrastructure changes start in version control. Pipelines validate and build each change, then run the relevant infrastructure and deployment steps: Terraform provisions infrastructure reproducibly where it applies, and deployment stages deliver workloads into the target environment.

The implementation differs between AWS, GCP and on-prem, but the workflow follows the same pattern everywhere: source change, automated validation, infrastructure and deployment, then delivery. Reusable pipeline templates and Terraform modules provide the common foundation.

High-level architecture

  1. Source

    • Application code
    • Infrastructure code
  2. Validation & Build

    • CI checks
    • Build / package
    • Deployment configuration
  3. Infrastructure & Deployment

    • Terraform modules
    • Reusable pipeline logic
  4. Targets

    • AWS
    • GCP
    • On-prem

Across every stage

  • Version control
  • Shared templates
  • Automation
Simplified, high-level view. Components are intentionally generic.

Outcome

Repeated, project-specific deployment work gave way to a more consistent delivery model across projects and environments. Deployments became more repeatable and infrastructure changes more consistent.

CI/CD and Terraform patterns were reused across projects, less duplicated pipeline logic made the setup easier to maintain, and developers had direct access to established deployment workflows. New deployment targets could be supported without rebuilding the delivery process from scratch.

Responsibilities
  • Designed and standardized deployment workflows across cloud and on-prem environments
  • Built reusable CI/CD pipeline patterns
  • Created and maintained reusable Terraform modules
  • Automated infrastructure provisioning and application delivery
  • Supported teams adopting the shared deployment patterns
  • Troubleshot and improved deployment workflows across environments
  • Maintained the shared delivery tooling as requirements evolved
Lessons & considerations
  • Standardization versus flexibility: shared pipelines should remove repeated work without blocking legitimate project-specific needs, and teams still need enough control over their own deployments.
  • Reuse versus complexity: reusable Terraform modules and CI templates only help if teams can understand and adopt them, so they had to stay simple.
  • Consistent, not identical: AWS, GCP and on-prem systems deploy differently, so the aim was a consistent delivery experience rather than identical implementation.
