Rachel Love — Solution Architecture Portfolio
Solution Architecture Case Studies
Architecture that connects business requirements, security, resilience, and operational reality.
This portfolio demonstrates how business problems are translated into technical requirements, architecture decisions, security controls, operational models, and implementation roadmaps. Each case study works through stakeholders, constraints, target architecture, trust boundaries, tradeoff analysis, architecture decision records, risks with owners, and a phased reference roadmap — with the reasoning made explicit rather than hidden behind the diagram.
Featured work
Three complete architecture case studies
Each is a hypothetical engagement worked end to end, from business driver to validated design.
Secure Cloud Migration
Modernizing a legacy on-premises business application into a segmented, observable cloud design.

Zero-Trust Enterprise Access
An identity-first access architecture that removes implicit network trust for people and workloads.
Read case study →
Resilient Data & Application Platform
Keeping a customer-facing application available and its data recoverable when infrastructure fails.

Method
Architecture approach
The same lifecycle runs through every case study, so decisions stay traceable back to the business problem.
- 01Business ProblemName the outcome the organization needs, in business language.
- 02StakeholdersIdentify who decides, who operates, and who is affected.
- 03RequirementsSeparate functional behaviour from measurable quality attributes.
- 04ConstraintsBudget, skills, timelines, and existing platform commitments.
- 05Architecture PrinciplesAgree the rules that make later decisions predictable.
- 06Target ArchitectureDefine tiers, boundaries, data flows, and trust zones.
- 07Security ControlsMap controls to boundaries, identities, data, and telemetry.
- 08Tradeoff AnalysisState what each option costs, not only what it gains.
- 09Architecture DecisionsRecord decisions as ADRs with context and alternatives.
- 10Risks & MitigationsTrack residual risk and an accountable owner.
- 11Implementation RoadmapSequence work so foundations precede migration.
- 12ValidationProve the design through testing, drills, and evidence.
Standards
Architecture quality principles
The non-negotiables applied across every design in this portfolio.
Security by design
Controls are part of the target architecture, not a later hardening pass.
Least privilege
Every human and workload identity gets the narrowest workable scope.
Defense in depth
No single control failure should expose data or the administrative plane.
Resilience
Assume component failure; design redundancy and graceful degradation.
Observability
Logs, metrics, and traces are centralized and correlated by request.
Recoverability
Backups are worthless until a restore has been tested and timed.
Automation
Repeatable pipelines and infrastructure definitions over manual change.
Maintainability
Prefer boring, documented patterns a small team can run at 3am.
Cost awareness
Design choices carry a run-rate; tag, budget, and review it.
Explicit architecture decisions
Decisions are written down with alternatives and tradeoffs.
Human accountability
Each risk, control, and environment has a named owning team.
Governance artifacts
Reusable architecture registers
Catalog, decisions, and risks are maintained as shared artifacts rather than per-project attachments.
Architecture components
A catalog of the building blocks used across the case studies, grouped by capability.
Open catalog →Decision register
Every ADR with status, reason, major tradeoff, and operational consequence.
Open decisions →Risk register
Synthetic risks with likelihood, impact, mitigation, residual risk, and an owning team.
Open risks →Disclosure
Responsible portfolio boundaries
- Educational portfolio demonstration using hypothetical organizations, synthetic data, and illustrative reference architectures. No production systems, customer environments, credentials, or proprietary configurations are represented. Framework and control references demonstrate architecture reasoning and do not represent certification, assessment, or compliance.
- Roadmaps are reference implementation sequences, not records of production delivery.
- Owners, organizations, metrics, and risks are synthetic examples created for this portfolio.
