🚀 IDP Portal – Internal Developer Platform (Backstage-based)

An enterprise-grade Internal Developer Platform (IDP) built on Backstage (CNCF).
It provides self-service infrastructure & application provisioning with guardrails, observability, compliance, and incident automation baked in.

---

🔹 Key Features

• Self-Service Developer Portal

  • Backstage Scaffolder templates for microservices & infra
  • GitHub repo + CI/CD pipeline auto-generated
  • ArgoCD GitOps-driven deployments

• Guardrails (Shift-Left Governance)

  • OPA/Kyverno policies (no public S3, restricted instances, mandatory labels)
  • Infracost cost estimates before provisioning
  • Approval workflows (Slack, Jira integration)
  • Quotas & resource limits (per team)

• Observability (SRE-first)

  • Prometheus + Grafana + Loki + Tempo stack
  • Golden Signals dashboards auto-provisioned per service
  • SLO Burn-rate alerts (Google SRE best practice)
  • Alertmanager routes to PagerDuty + Slack + Jira

• Compliance & FinOps

  • Cloud Custodian scans (S3, EC2, tags, cost controls)
  • Continuous compliance reporting under compliance/scans/

• Incident Automation

  • PagerDuty escalation policies
  • Slack bot creates incident channels
  • Jira tickets auto-created for tracking

🔹 Setup Instructions

See full guide: docs/setup_guide.md

Quick start:

# Deploy Backstage
cd infra/helm-charts/backstage
helm upgrade --install backstage . -n idp-system --create-namespace -f values.yaml

# Deploy Observability
cd infra/helm-charts/observability
helm upgrade --install observability . -n monitoring --create-namespace -f values.yaml

# Provision Infra
cd infra/terraform/vpc
terraform init && terraform apply

🔹 Documentation

• Architecture Decision Notes
• Workflow Diagram + PlantUML
• Setup Guide
• Plugins Guide
• SRE Guardrails

---

🔹 Extensibility

• Add new Scaffolder templates for ML workloads, data pipelines, serverless apps.
• Extend Guardrails with additional OPA/Kyverno policies.
• Add multi-cloud Terraform modules (Azure, GCP).
• Integrate custom observability dashboards per team.

---

🔹 Roadmap

• ✅ Phase 1: MVP (Backstage + ArgoCD + Helm + Terraform)
• ✅ Phase 2: Guardrails (OPA, Infracost, Approvals, Quotas)
• ✅ Phase 3: Observability, Compliance, Incident Automation
• ⏳ Phase 4: Advanced plugins (ML Ops, GitOps insights, Chaos Engineering)

---

🔹 Summary

This IDP empowers developers to self-serve infra & apps while enterprises maintain control, cost visibility, compliance, and reliability.
Built on open-source CNCF projects, it’s future-proof, cloud-agnostic, and SRE-first by design.
