Architecture Principles and Standards Catalogue
Enterprise software architecture constitution defining foundational design principles, approved technology stacks, architectural invariants, golden paths, and technical deviation waiver rules.
Authoritative enterprise architecture principles catalog establishing build-vs-buy tenets, cloud-native standards, event-driven rules, and approved technology stacks across engineering squads.
Important Tech Document Template & Operational Notice
TinyCTO.tv Tech Document Template Notice: This template is a general educational and operational starting point. It is not legal, tax, accounting, investment, procurement, regulatory, security or certification advice. Requirements vary by jurisdiction, organization, contract and risk. Review and adapt it with qualified professionals before relying on it.
Problem Solved
Engineering squads adopt random, unvetted databases, languages, and frameworks in isolation, creating unmaintainable technology sprawl, severe security vulnerabilities, and fragmented hiring requirements.
When to Use
- •Establishing enterprise-wide architectural guidelines and approved technology choices for engineering squads
- •Conducting design reviews and gating architectural deviations before code development commences
- •Onboarding new engineering teams and establishing coherent golden paths for microservices and cloud infrastructure
When NOT to Use
- •For single low-level API interface schema definitions (use TPL-ARC-004)
- •For project delivery sprint schedules and burndown velocity tracking (use TPL-DEL-004)
5 Template Sections & Structural Outline

Architecture Principles and Standards Catalogue - Worked Case Study
Fictional Entity: Sovereign Cloud Platform Enterprise Architecture Constitution
Real-world production case study demonstrating complete operational adoption for Sovereign Cloud Platform Enterprise Architecture Constitution.
- •Codified 12 core architecture principles and an approved Technology Radar across 45 engineering squads
- •Eliminated 6 shadow databases and 4 disparate programming languages, reducing cloud licensing by $1.2M
- •Accelerated new service spin-up time from 3 weeks to 2 hours using standardized Golden Path templates
Frequently Asked Questions
What is the TOGAF standard format for documenting architecture principles?
TOGAF specifies four components for each principle: Name (clear and memorable), Statement (unambiguous declarative rule), Rationale (business and technical justification), and Consequences (operational impacts and trade-offs).
What is a "Golden Path" in platform engineering?
A Golden Path is an opinionated, well-supported, and automated path for developers to build, test, and deploy applications. It does not prevent alternative paths, but makes following company standards the fastest and easiest option.
How should an Architecture Review Board handle technology waivers?
Waivers must be granted sparingly, for a strictly defined duration (e.g. 6 months), with an explicit remediation plan to bring the system back into compliance, preventing temporary shortcuts from turning into permanent technical debt.
