how systems should be shaped
spec
V.0.1.0
architecture, for me, is less about collecting tools and more about shaping systems people can operate: clear boundaries, reusable patterns, and honest tradeoffs across platforms, networking, security, and applications.
principles
1.1
platforms over projects
prefer reusable services and paved roads over isolated one-off solutions that only the original engineer understands.
1.2
ownership is an interface
define what the platform owns, what application teams own, and where responsibility is shared — ambiguity becomes outage fuel.
1.3
design for operability
observability, lifecycle, certificates, capacity, and incident learning are architectural concerns, not optional extras.
1.4
security in the path
private networking, identity, policy, and scanning should be integrated into delivery paths — not bolted on after production.
1.5
distributed systems humility
many “kubernetes problems” are dns, routing, firewall, identity, certificate, storage, or application problems wearing a cluster costume.
1.6
document the decision
option analysis and tradeoff writeups help stakeholders choose deliberately — especially for gpu, networking, and lifecycle decisions.
cross-domain troubleshooting
Application → Kubernetes → Operating System → Network → DNS → Load Balancer → Firewall → Cloud → Storage
