Capture one design rule you would reuse when reviewing an AI workload, assistant, or operating model.
Executive note
The Core Idea
SRE and platform engineering both grew from the need to operate software reliably at speed. SRE focuses on reliability engineering and service health. Platform engineering focuses on reusable internal platforms that make good delivery patterns easier for teams.
They are not replacements for DevOps. They are ways to make DevOps practical at enterprise scale.
Section 2 of 7
Plain-English Vocabulary
- SRE: Site Reliability Engineering, a discipline that applies engineering to operations and reliability.
- SLO: Service Level Objective, a target for acceptable reliability.
- Error budget: the amount of unreliability a service can tolerate before reliability work should take priority.
- Platform engineering: building internal platforms, templates, pipelines, and golden paths.
- Golden path: a recommended, supported way to build and run a common type of workload.

Realistic Scenario
Several teams deploy services to Kubernetes, but each team invents its own logging, secrets, ingress, deployment, and monitoring pattern. Delivery slows down because every team solves the same problems differently.
A platform team provides approved templates, GitOps patterns, gateways, observability, identity integration, and deployment pipelines. SRE practices define reliability expectations and incident response. Product teams still own their services, but they build on stronger foundations.

Why It Matters
As cloud adoption grows, complexity moves from hardware management to platform and service management. SRE helps decide how reliable a service needs to be. Platform engineering helps teams reach that standard without rebuilding the same controls.

Common Misunderstandings
- SRE is not only production support.
- Platform engineering is not a ticket desk for infrastructure.
- Golden paths are not meant to block innovation; they reduce repetitive design work.
- Reliability is a business decision, not only an engineering preference.

Recommended Practices
- Define reliability expectations in language business and IT both understand.
- Use platforms to standardize common controls.
- Keep product teams accountable for their runtime behavior.
- Measure adoption and friction, not only platform availability.

How To Talk About This With IT
Ask: "Which reliability target does this service need, and which platform golden path helps us reach it with less custom work?"
