platform-engineering-lab is a production-grade monorepo that demonstrates how a modern Internal Developer Platform (IDP) can be designed and operated with Site Reliability Engineering principles at its core.
This repository brings together:
- Application Delivery — Three-tier services with scalable architecture
- CI/CD Standardization — GitHub Actions & Jenkins pipelines
- Platform Infrastructure — Kubernetes, networking, and API gateway
- Observability & Reliability — Comprehensive monitoring and recovery tooling
- Security & Compliance — Guardrails and policy enforcement
The goal is to model how platform teams enable developer velocity while preserving production stability.
| Principle | Description |
|---|---|
| Platform as a Product | Shared capabilities are opinionated, reusable, and versioned. |
| Reliability by Default | Backups, observability, and recovery are first-class citizens — not afterthoughts. |
| Separation of Concerns | Clear boundaries between application logic, platform services, and SRE controls. |
| Everything as Code | Infrastructure, pipelines, dashboards, and policies are Git-versioned. |
This repository is intentionally organized around responsibility, not tools.
These folders represent what the platform provides to application teams.
What it is: Self-contained three-tier applications (frontend, backend, database)
Platform responsibility:
- Define golden paths for application structure
- Standardize deployment and Helm patterns
What it is: CI/CD tooling and pipelines
- GitHub Actions workflows
- Jenkins pipelines and shared libraries
Platform responsibility:
- Provide reusable CI/CD templates
- Enforce consistent build, test, and deploy flows
- Enable safe and repeatable delivery
What it is: Core shared infrastructure and runtime components
Includes:
- Kubernetes primitives (namespaces, ingress, networking)
- KrakenD API Gateway configuration
- Terraform modules & environment definitions
- Ansible playbooks and roles
Platform responsibility:
- Abstract infrastructure complexity
- Provide stable, shared runtime services
- Enable multi-environment parity
What it is: Policy, secrets, and security automation
Includes:
- OPA / Kyverno policies
- Secrets management integrations
- Image and dependency scanning
Platform responsibility:
- Enforce security guardrails
- Shift security left without slowing developers
These folders represent how reliability is enforced across the platform.
What it is: Metrics, logs, dashboards, and alerting
Includes:
- Grafana dashboards
- Prometheus rules
- Loki / Tempo configurations
SRE responsibility:
- Make system behavior visible
- Detect issues early
- Enable fast diagnosis
What it is: Reliability and resilience tooling
Includes:
- Custom database backup and restore solution
- Disaster recovery scripts and runbooks
- SLOs, SLIs, and error budgets
- Chaos engineering experiments (optional)
SRE responsibility:
- Ensure recoverability
- Define and measure reliability targets
- Minimize blast radius during failures
Architecture diagrams, runbooks, onboarding guides, and standards.
Bootstrap and helper scripts — no business logic.
- How Platform Engineering and SRE complement each other
- How reliability can be designed into the platform, not bolted on
- How to scale delivery without sacrificing stability
- Platform Engineers
- Site Reliability Engineers
- Senior DevOps Engineers
- Cloud / Kubernetes Engineers
This repository is intentionally designed to reflect real-world platform team practices rather than toy examples. Every folder represents an ownership boundary and an operational responsibility.
