… — the BlueMix lessons, sovereign
The enterprise-PaaS governance the BlueMix Gen3/Gen4 diagrams model, done light + sovereign.
Account tiers (admission.py) — BlueMix entitlement/Free-Paid, as quota + backend entitlement:
- TIERS free|pro|enterprise: each sets max_concurrent/gpu_max/cost_budget AND allowed_backends
(free -> local/wasm only; pro -> +k8s/hpc/volunteer; enterprise -> all).
- AdmissionController(tiers={subject: tier}); quota_for applies the tier (explicit quotas still
override); allowed_backends(subject) feeds compute_plane.place() policy. Default tier: pro.
- free tier denies GPU work (gpu_max 0), fail-closed.
Availability-maturity grade (availability.py) — the DW-DevOps Zero-Downtime legend as a governance
artifact (like the commons' reproducible/declared grade):
- GRADES: non-managed -> needs-work -> almost-zd -> zero-downtime.
- a CapD declares policy.availability; estate_availability() reports per-capability grades + a
histogram (default non-managed). Honest grades added: compute-plane needs-work; commons /
verification / data-spheres almost-zd.
Tests: +5 tier +2 availability = 147 tools tests green. validate REQUIRED + Makefile `availability`.
Completes the three PaaS-lesson units (dev-mode #28, data-spheres #29, tiers+availability).
