GPUaaS Review Portal

A fact-based review surface for the Core42 GPUaaS platform. Curated for product, architecture, operations, security, and developer teams.

Every claim on this site is traceable to code (cmd/, packages/), contract (openapi.draft.yaml, asyncapi.draft.yaml), schema (db_schema_v1.sql), runbook (doc/operations/runbooks/), or RCA (doc/rca/). No roadmap, no aspirational content — only what exists today and what has been formally designed.

Pick your entry point

Product

PRD, personas, user journeys, UX information architecture, V3 redesign status.

Architecture

As-built C4, domain ownership, allocation lifecycle, outbox & events, GPU slice internals.

Developers

Repo layout, coding/test patterns, contract workflow, CI gates, quick-start.

Operations

Runbook index, observability, incident severity, lab topology, local-dev setup.

Security & Governance

Threat model, governance precedence, audit & compliance, sanitize-first rules.

What exists today

Fact dashboard: binaries, packages, SKUs, contracts, runbooks, RCAs.

Status legend

Every detail page carries one or more of these badges so reviewers instantly know what level of evidence backs the page.

Implemented Backed by code in cmd/ or packages/. Callable today.

Contract Defined in openapi.draft.yaml or asyncapi.draft.yaml.

Designed A spec exists in doc/ but is not yet end-to-end in code.

Decided Decision recorded; implementation may be partial.

Runbook Has an operational runbook.

RCA Documented post-incident analysis.

Deprecated Being retired.

What the platform is

Core42 GPUaaS is a contract-first GPU cloud control plane. Users discover GPU capacity, provision allocations (full bare-metal nodes or GPU slice VMs), open browser terminals or SSH into them, run platform apps (Jupyter, vLLM, Slurm, RKE2), and pay per usage. Admins manage inventory, audit, and refunds.
