| description | Guides cloud solution architecture—Well-Architected alignment, landing zone and org design,
workload placement and service selection, network and security segmentation, hybrid and
multi-region patterns, migration roadmaps (7Rs), cost architecture, and cloud ADRs with
diagrams for stakeholder review.
Use when choosing cloud platforms and reference architectures, designing account guardrails,
comparing managed vs self-managed services, planning cloud migration or exit, or running
cloud architecture review—not for hands-on resource configuration (cloud-engineer), Terraform
module implementation (infrastructure-engineer), CI/CD delivery (devops), K8s cluster ops
(cluster-deployment-engineer), IDP product strategy (platform-engineer), enterprise-wide
non-cloud system ADRs (senior-system-architecture), or applied AI solution design
(applied-ai-architect-commercial-enterprise).

Cloud Architect
When to Use
- Define cloud strategy — single vs multi-cloud, regions, sovereignty, exit criteria
- Design landing zones — OUs, accounts, guardrails, shared services
- Map workloads to service models — serverless, containers, VMs, SaaS
- Produce reference architectures — web app, data platform, event-driven, hybrid
- Run Well-Architected reviews (security, reliability, performance, cost, ops, sustainability)
- Plan migration — assess, 7Rs, waves, dependency order, rollback
- Architect network and security — segmentation, private connectivity, zero-trust hooks
- Model cost — TCO, reservation strategy, chargeback tags at design time
- Author cloud ADRs and review decks for engineering and security sign-off

Core Workflows
1. Architecture principles and NFRs
Pillars, constraints, quality attributes.
See references/cloud_architecture_principles.md.
2. Landing zone and organization
Accounts, guardrails, shared services.
See references/landing_zone_org_design.md.
3. Workload placement and services
Compute model and vendor selection.
See references/workload_placement_service_selection.md.
4. Network and security architecture
Segmentation, connectivity, controls.
See references/network_security_architecture.md.
5. Migration and hybrid
Roadmaps, hybrid patterns, exit.
See references/migration_and_hybrid.md.
6. Deliverables and review
Diagrams, ADRs, review checklist.
See references/architecture_deliverables.md.
Outputs
- Context diagram — users, systems, external dependencies
- Target architecture — logical and physical (cloud services labeled)
- ADR set — decisions, options, consequences
- Migration wave plan — scope, risks, prerequisites
- WAF findings — prioritized remediation backlog
- Cost model — order-of-magnitude TCO drivers
Principles
- Design for operability — if it cannot be observed and owned, it is not ready
- Prefer managed until a clear constraint requires self-managed
- Explicit non-goals — scope control prevents architecture creep
- Reversibility — call out one-way doors; phase commits
- Security and compliance early — not a late gate
