Reference solutions for ai-infra-principal-architect-learning.
This repository is the answer key for an unusual kind of curriculum. A principal architect operates above the level where solutions look like code. The deliverables here are investment theses, coalition plans, standards positions, and modernization sequences — written artifacts a senior leader would defend in an executive review or an industry working group.
If you came looking for runnable code, see the architect or senior- architect tracks. This one is deliberately upstream of those.
Module-level SOLUTION.md design-rationale docs for all 5 modules (mod-601 org-wide-architecture, mod-602 industry-standards, mod-603 multi-year-investment, mod-604 stakeholder-coalition, mod-605 tech-debt-modernization). Each doc explains what the strategic deliverables (case study, strategy memo, stakeholder map, roadmap, presentation) should actually look like at the principal-architect level, with common failure modes and the why behind the rubric. Audit score: 45 → 55.

| Module | Discipline |
|---|---|
| mod-601-org-wide-architecture | Architecture that survives across business units and through reorganizations. |
| mod-602-industry-standards | Engaging with — and shaping — standards bodies, open-source consortia, and regulatory dialogue. |
| mod-603-multi-year-investment | Capital-allocation reasoning for technology investments with 3-10 year arcs. |
| mod-604-stakeholder-coalition | Building and sustaining the cross-functional coalitions that turn strategy into adoption. |
| mod-605-tech-debt-modernization | Sequencing the modernization of legacy systems without crashing the business. |
Each module contains five exercise-level solutions. The shape of a
"solution" here is a strategic position document, a decision rationale,
an influence plan, a failure-mode analysis, or a success-criteria
scorecard — see SOLUTION_OVERVIEW.md.
These are the load-bearing ideas the track returns to repeatedly:
- Strategy is what survives stakeholder rotation. A strategy that depends on a specific executive sponsor is not a strategy; it is a project. Deliverables are written to outlive the people who commissioned them.
- Standards engagement is leverage, not vanity. Influencing industry standards (CNCF, MLCommons, NIST AI RMF) shifts the playing field for every competitor.
- Tech-debt modernization is sequenced by blast radius. The job is not "rip and replace"; it is sequencing — what can change first because it fails small, what must change later because it fails large.
- Aspiring to the role: read in module order; spend the most time
in
mod-603andmod-604. - Already a principal architect: skim and steal the templates; the value is concentrated in the anti-pattern sections.
- Executive evaluating "do we need a principal architect?": read
mod-601andmod-603only. If your org has neither of those disciplines staffed elsewhere, you need a principal architect.
See LEARNING_GUIDE.md for a structured reading
plan.
- Senior Architect track (recommended).
- Alternative path: Principal Engineer track for technical principals.
The track produces artifacts of this shape:
- Three- to five-year AI infrastructure investment thesis aligned to a measurable business strategy.
- Technology evaluation framework adopted as a standard across an engineering org.
- Architecture governance model (review boards, ADRs, technical standards) for an enterprise.
- Executive-level technical strategy briefings.
- Multi-million-dollar cost-optimization programs.
- Organization-wide technology migrations executed with zero business disruption.

contributions in the form of additional case studies, alternative
templates, and corrections — but not "runnable code" PRs (wrong
track).
