Architecture Domain

Domain · DOM09

Deep Dive: DOM09 — Architecture Domain (Solutions / Cloud / Enterprise / Domain)

Version: 1.0
Date: April 2026
Scope: Enterprise, Solution, Cloud, and Domain Architects; career pathways; certifications; frameworks; and practical skills.


Executive Summary

The Architecture domain spans the design and governance of IT systems at scale—from a single project solution (Solutions Architect) to the entire enterprise technology portfolio (Enterprise Architect). It sits at the intersection of business strategy and technical implementation. Career progression typically moves: Engineer → Solutions Architect → Enterprise Architect → Chief Architect, with lateral specializations into Security Architect, Data Architect, Cloud Architect, and Network Architect roles.

Key certifications anchor this domain:

  • TOGAF (The Open Group) — enterprise framework standard (now TOGAF 10th Edition, released April 2022)
  • Open CA (Certified Architect) — independent portfolio-based certification
  • AWS Solutions Architect Professional (SAP-C02) — cloud-focused
  • Microsoft Azure Solutions Architect Expert (AZ-305) — Azure-focused
  • GCP Professional Cloud Architect — Google Cloud
  • SAFe Architect (ARCH) — scaled agile delivery context
  • Industry-specific frameworks (BIAN for banking, TM Forum for telecom, HL7 FHIR for healthcare)

This domain has no single tech stack—instead, architects work across all domains (networking, cloud, security, data, DevOps, etc.) to compose integrated solutions.


1. What Architects Do: Role Definitions & Scope

1.1 Solutions Architect

Scope: Single project or product initiative, typically 6–18 months.

Responsibilities:

  • Translate business requirements into technical architecture
  • Design system components (compute, storage, networking, security)
  • Evaluate trade-offs: cost, scalability, availability, performance, security
  • Work directly with engineers, product managers, and stakeholders
  • Own the design through implementation and early operation

Typical Tenure: 3–7 years as solutions architect before promotion to enterprise or specialization.

Report To: VP Engineering, VP Product, or Solutions leadership.

Day-to-Life Example:

  • Morning: stakeholder meeting to clarify SLOs (service-level objectives), compliance constraints, budget.
  • Mid-day: sketch architecture diagram, evaluate 3 candidate approaches (cloud vs. on-prem, serverless vs. containers, etc.), cost modeling.
  • Afternoon: review code review patterns, security review with CISO office, negotiate with ops on runbook/monitoring strategy.

Key Skill Areas: system design, trade-off analysis, communication across silos, cost optimization, risk assessment.

1.2 Enterprise Architect

Scope: Entire technology portfolio, 3–5 year horizon, cross-business-unit alignment.

Responsibilities:

  • Define enterprise architecture standards, frameworks, and governance
  • Manage technology portfolio roadmap (what to modernize, consolidate, retire)
  • Ensure architectural consistency across solutions architects' projects
  • Lead capacity planning, vendor strategy, and major platform decisions (e.g., cloud migration)
  • Communicate with CFO, board, and business unit leaders on IT-business alignment

Typical Tenure: 5–15 years as enterprise architect; often a prerequisite for Chief Architect or CIO.

Report To: CIO, Chief Technology Officer (CTO), or VP Enterprise Architecture.

Day-to-Life Example:

  • Morning: executive steering committee meeting on cloud migration ROI and timeline.
  • Mid-day: review architectural standards document for microservices adoption; work with solutions architects to ensure compliance.
  • Afternoon: vendor evaluation for new data warehouse platform; capacity planning for next fiscal year.

Key Skill Areas: portfolio management, organizational change, strategy, governance, vendor/platform evaluation.

1.3 The Architect Elevator Metaphor (Gregor Hohpe)

Core insight: Modern architects must "ride the elevator" between the business penthouse (board room, CFO, business strategy) and the technical engine room (developers, ops, code). Neither alone is sufficient.

  • Penthouse: Understand business outcomes, ROI, competitive positioning, transformation roadmaps.
  • Engine Room: Deep technical knowledge of systems, scalability patterns, cloud platforms, deployment automation.
  • Elevator: The skill to translate between these worlds—explaining why a technology choice matters to CFO, or why a business constraint changes the architecture.

Source: The Software Architect Elevator: Redefining the Architect's Role in the Digital Enterprise by Gregor Hohpe, O'Reilly, 2020. Hohpe also served as Chief Architect at Allianz SE and technical director at Google Cloud's Office of the CTO.

1.4 Domain Architects (Specialization)

Definition: Architects who own a specific technical domain across the enterprise. Examples:

  • Security Architect — security design, compliance, zero-trust models, governance (covered separately in Security domain; key certs: CCSP, SC-100)
  • Data Architect — data warehouses, lakes, governance, MDM (master data management); certs: Snowflake Architect, Cloud Data Engineer
  • Network Architect — network topology, SD-WAN, cloud networking, hybrid connectivity; cert: CCDE, Open CA
  • Cloud Architect — cloud platform strategy, multi-cloud, migration patterns, cost optimization
  • Integration/API Architect — microservices, event-driven, API design, message buses

Domain architects report to either the enterprise architect or their own VP, and coordinate across solutions architect teams to enforce standards.


2. Certifications & Credentials

2.1 The Open Group: TOGAF (The Open Group Architecture Framework)

What It Is: Industry-standard enterprise architecture framework, defines a structured methodology (ADM, Architecture Development Method) for designing and governing enterprise IT systems.

Current Version: TOGAF 10th Edition (released April 25, 2022, officially TOGAF® Standard, 10th Edition). TOGAF 9 certifications remain valid and widely used; TOGAF 10 is the forward direction.

Key Differences: TOGAF 9 vs. TOGAF 10

  • Modularity: TOGAF 10 introduces a modular structure (Fundamental Content + Series Guides), making the framework less monolithic and easier to adopt selectively.
  • Agile Focus: TOGAF 9.2 lacks specific Agile integration guidance. TOGAF 10 includes detailed guidance on applying Agile practices alongside the ADM.
  • Modern Tech: TOGAF 10 adds explicit coverage of digital transformation, cloud computing, and microservices architecture.
  • Digital Edition: TOGAF 10 includes a digital (interactive) version with feedback mechanisms for practitioners.

3. Frameworks & Practical Methodologies

3.1 TOGAF ADM (Architecture Development Method)

The TOGAF ADM provides a structured, repeatable methodology for enterprise architecture work:

PhaseFocusDuration
A. Architecture VisionDefine scope, business objectives, architecture principles1–2 weeks
B. Business ArchitectureCapability mapping, process design, organization design2–4 weeks
C. Information Systems ArchitectureData, applications, integrations2–4 weeks
D. Technology ArchitectureInfrastructure, platforms, tools2–4 weeks
E. Opportunities & SolutionsConsolidation, migration, transformation roadmap1–2 weeks
F. Migration PlanningPhasing, dependencies, dependencies, governance1–2 weeks
G. Implementation GovernanceOversee realization, manage changeOngoing
H. Architecture Change ManagementMonitor, feedback loops, continuous improvementOngoing

Capability Mapping (Phase B): Architects define what capabilities the business needs (e.g., "real-time fraud detection," "omnichannel customer service") and map those to existing and future technology solutions. This bridges business and IT language.

3.2 Architecture Decision Records (ADRs)

What They Are: Lightweight documentation of why architectural choices were made, not just what was chosen.

Standard Format (Cognitect/Joel Parker Henderson template):

# ADR-001: Use PostgreSQL for Primary Datastore

## Status
Accepted

## Context
We need a relational database for order management and reporting. 
Evaluated: PostgreSQL, MySQL, managed database-as-a-service.

## Decision
We will use PostgreSQL (self-managed in Kubernetes, backed by persistent volumes).

## Consequences
- Positive: Rich SQL, JSONB support, cost-effective at our scale
- Negative: Ops responsibility for backup/recovery/tuning
- Risk: Skills gap in team; mitigated by hiring DBA, training

Best Practices:

  • Keep ADRs in version control (git) alongside code, in doc/adr/ or similar
  • Write in Markdown, one file per decision
  • Append-only: don't edit accepted records; if a decision changes, write a new ADR that supersedes the old one
  • Link superseding ADRs to original ones
  • Keep records short: 1–2 pages typical

Visibility: ADRs serve dual purpose: (1) documentation for future engineers, (2) forcing architects to articulate reasoning upfront, which often surfaces flaws in thinking.

3.3 Architectural Characteristics & Patterns

Modern architecture work centers on identifying and balancing non-functional requirements:

Common Architectural Characteristics:

  • Scalability — horizontal scale, elasticity, throughput
  • Availability & Resilience — uptime, fault tolerance, recovery time
  • Performance — latency, bandwidth, throughput SLOs
  • Security — confidentiality, integrity, compliance (SOC2, ISO 27001, HIPAA, PCI-DSS)
  • Cost — CapEx, OpEx, cloud spend optimization
  • Maintainability — code clarity, modularization, testability
  • Deployability — CI/CD, blue-green, canary, GitOps
  • Operational Excellence — monitoring, alerting, runbooks, incident response

Common Patterns:

  • Microservices — distributed services, independent deployment, polyglot
  • Serverless — functions-as-a-service, event-driven, managed backends
  • Event-Driven — asynchronous, decoupled, real-time
  • CQRS — Command Query Responsibility Segregation
  • Domain-Driven Design (DDD) — bounded contexts, ubiquitous language
  • API-First — REST, gRPC, GraphQL, contract-driven

Cost-of-Living Adjustment: San Francisco Bay Area, Seattle, NYC, Boston all command +20–40% premiums. Remote roles from lower-CoL regions often negotiate +10–15% above stated ranges.

4.3 Career Advancement Tactics

Deep Specialization vs. Generalization:

  • Years 0–3: Pick one cloud platform (AWS, Azure, GCP) and go deep. Specialists reach senior roles 1–2 years faster than multi-cloud generalists.
  • Years 4–7: Add a second platform or specialization (security, data, network); you're now "deep + adjacent."
  • Years 8+: Breadth becomes valuable. Principal/chief architects need portfolio-level views (when to use AWS vs. Azure, multi-cloud strategy, M&A due diligence).

Visibility & Communication:

  • Architect's work is invisible unless communicated. Present at all-hands, write decision docs, blog internally, give lunch-and-learns.
  • Attend industry conferences (O'Reilly Software Architecture, QCon, GOTO, domain-specific conferences).
  • Publish externally (technical blog, conference talk) to build credibility for next role (CTO office, chief architect, board advisor).

Build a Portfolio:

  • Document 3–5 significant architectural decisions, impacts (cost savings, reliability improvements, faster time-to-market), and lessons learned.
  • For Open CA, a documented portfolio is the requirement; start building this early.

6. Cross-Domain & Emerging Trends

6.1 Architecture + Cloud Adoption

Modern architecture nearly always intersects with cloud strategy. Key patterns:

  • Lift-and-Shift (rehost): Move apps as-is to cloud. Quick, but misses optimization.
  • Re-Platform (managed services): Refactor for cloud databases, caching, etc. Moderate effort, good ROI.
  • Re-Architect (cloud-native): Microservices, containers, serverless, event-driven. High effort, long-term advantage.
  • Retire or Replace (rationalization): Sunset legacy systems; replace with SaaS.

Architects own the "6R" strategy decision and manage the roadmap. Cloud platform architects (AWS, Azure, GCP) are increasingly specialized roles.

6.2 Architecture + AI/ML

Emerging concern: Generative AI (LLMs) and ML models introduce new architectural requirements:

  • Model Serving — inference endpoints, batch processing, edge deployment
  • Data Pipelines — feature engineering, training data management
  • Governance & Bias — model versioning, explainability, compliance
  • Cost — GPU/TPU provisioning, inference cost optimization
  • Safety/Guardrails — prompt injection, hallucination mitigation

New specialization: AI/ML Architect, bridging data science and infrastructure.

6.3 Architecture + DevOps / Site Reliability

Modern architects design for operational excellence:

  • Observability — metrics, logs, traces; architects define SLI/SLO/SLA contracts
  • Infrastructure-as-Code (IaC) — Terraform, CloudFormation; architects own the IaC strategy
  • Continuous Delivery — architects ensure architecture supports deployment frequency
  • Chaos Engineering — architects define failure modes and resilience testing strategy

Key credential overlap: SRE Engineer (Google) / Site Reliability Professional certifications; increasingly architects need hands-on SRE knowledge.

6.4 Architecture + Security

Zero-trust, least-privilege, defense-in-depth are now architectural non-negotiables, not just security concerns. Architects work closely with Security Architects (CCSP, SC-100 certified).


7. Real-World Example: Solutions Architecture Project

Scenario: A SaaS company is migrating from monolith (on-premise datacenter) to microservices on AWS. Solutions Architect's role:

Phase 1: Architecture Vision (Week 1–2)

  • Stakeholder interviews: product, eng, ops, finance
  • Define architectural characteristics: scalability (10x user growth in 2 years), cost (50% reduction), reliability (99.95% uptime)
  • Set constraints: team size (20 engineers), budget ($2M/year), timeline (12 months)

Phase 2: Solution Design (Week 3–6)

  • Service decomposition: identify 8 core microservices (user, order, payment, inventory, notification, billing, analytics, admin)
  • Technology choices: ECS Fargate (vs. EKS), RDS Aurora (vs. DynamoDB), S3 + CloudFront, SQS for async, Lambda for scheduled jobs
  • Trade-off analysis:
    • Serverless (Lambda everywhere): Lower ops cost, but cold starts + vendor lock-in. Decision: reject for core services, use for edge cases.
    • Managed databases (Aurora, ElastiCache): Higher cost, lower ops burden. Decision: accept for reliability SLO.
  • Cost estimate: $80K/month baseline, auto-scaling to $180K/month at peak.

Phase 3: Governance & ADRs (Week 7–8)

  • Write ADRs for key decisions: ECS Fargate over Kubernetes, Aurora over Cosmos DB, blue-green deployments vs. canary
  • Define architectural standards: API versioning (semantic), logging format (JSON), monitoring (CloudWatch + Datadog), security (TLS 1.3, mTLS internal)

Phase 4: Implementation Handoff (Week 9+)

  • Review with engineering team; answer design questions
  • Work with ops on monitoring, alerting, runbooks, disaster recovery procedures
  • Review early PRs for architectural compliance
  • Attend weekly architecture review meetings; identify deviations early

Outcome: Microservices live in 12 months; 40% cost reduction (better than budget), 99.98% uptime (exceeds target), 50% faster feature deployment. Architect's work cited in company blog, becomes basis for promotion to principal architect role.


8. Distinctions & Overlaps with Other Domains

Architecture vs. Other IT Domains

DomainFocusOverlap with Architecture
Software EngineeringCode quality, testing, deliveryArchitects set design constraints (patterns, style guides); engineers implement
CloudPlatform services, optimizationCloud architect is specialization within architecture domain
DevOps/SREDeployment, observability, reliabilityArchitects design for deployability/observability; DevOps engineers execute
SecurityRisk, compliance, threat modelingSecurity Architect is specialization; coordinates with enterprise architect on governance
DataWarehouses, pipelines, analyticsData Architect specialization; works with enterprise architect on data governance
NetworkingTopology, protocols, performanceNetwork Architect specialization; increasingly cloud-networking focused

Not Architecture

  • Project Management — roadmaps, timelines, resource allocation (related, but not architecture)
  • IT Operations — server administration, incident response (operations executes architect's design)

Appendix B: Architecture vs. Related Paths

If you're interested in this domain but unsure of fit:

  • Engineer → Architect (this path): Design thinking, communication across silos, trade-off analysis, strategic vision.
  • Engineer → DevOps/SRE: Operations, reliability, deployment automation, observability.
  • Engineer → Manager: People leadership, hiring, career development, P&L responsibility.
  • Engineer → Specialist (Security, Data, Network): Deep domain expertise, certifications, thought leadership.

Architecture requires breadth and depth: technical chops + communication + business acumen. If you prefer pure coding or deep specialization, DevOps/SRE or specialist paths may be better fit.
