Platform Engineering 101: Why DevOps is Dead (Long Live DevOps)

"You build it, you run it." It sounded great in theory. In practice, it turned developers into amateur sysadmins, drowning in YAML files and Kubernetes manifests.

Enter Platform Engineering.

The Cognitive Load Problem

Modern cloud-native architectures are complex. Expecting every product developer to master Terraform, Helm, Istio, and Prometheus is unrealistic and inefficient.

Platform Engineering is the discipline of designing and building toolchains and workflows that enable self-service capabilities for software engineering organizations in the cloud-native era.

The Internal Developer Platform (IDP)

The IDP is the product you build for your internal customers (developers). It acts as a "Golden Path" (or Paved Road).

Key Components of an IDP

1. Developer Control Plane: The interface (CLI, GUI, API) developers interact with. Example: Backstage.
2. Integration Plane: The glue that connects tools. Example: Crossplane.
3. Infrastructure Plane: The actual compute/storage. Example: AWS/EKS.

Building with Backstage

Spotify's Backstage has become the de-facto standard for IDP frontends.

# catalog-info.yaml
apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
  name: payment-service
  description: Handles credit card processing
  tags:
    - java
    - payments
spec:
  type: service
  lifecycle: production
  owner: team-payments
  system: payment-system

Treating Platform as a Product

The biggest mistake platform teams make is building what they think developers need. Instead:

1. User Research: Interview your developers.
2. MVP: Start small (e.g., a simple deployment CLI).
3. Marketing: Evangelize your platform internally.

Conclusion

DevOps isn't dead; it has evolved. Platform Engineering is the industrialization of DevOps principles, allowing organizations to scale without burning out their developers.
