Abstract — Portuguese
Cloudless architectures for IoT with data sovereignty and local edge processing. The central problem investigated is: Public cloud dependence expands the attack surface, latency, and regulatory exposure of sensitive data. A methodological design was adopted focusing on internal validity, comparability, and reproducibility: Comparison of centralized versus edge-first architectures, including identity, encryption, and observability requirements. The main results indicate that the cloudless design reduces external dependence and improves control over local confidentiality and availability. The methodological contribution includes an audit-oriented scientific writing standard, with premise tracking, boundary delimitation, and explicit connection between theory and implementation implications. The objective of this work is to structuredly evaluate how "Cloudless Architectures and Data Sovereignty in IoT" can generate scientific and operational value with methodological traceability. In summary, the study offers a technical basis for decision-making with verifiable bibliography and guidance for a DOI-ready version. (Rose, 2020).
Abstract — English
This article presents a reproducible, high-rigor synthesis of "Arquiteturas Cloudless e Soberania de Dados em IoT" by aligning methodological traceability, interdisciplinary evidence, and operational recommendations for deployment contexts with explicit governance constraints. (Fagan, 2020).
Introduction
In the current state of the topic, public cloud dependence expands the attack surface, latency, and regulatory exposure of sensitive data. Cloudless architectures for IoT with data sovereignty and local edge processing. (security, 2026).
The research gap lies in the absence of integration between theoretical formulation, operational criteria, and transparent validation mechanisms. The objective of this work is to structuredly evaluate how "Cloudless Architectures and Data Sovereignty in IoT" can generate scientific and operational value with methodological traceability. (cybersecurity, 2026).
Research question: Which architectural decisions derived from "Cloudless Architectures and Data Sovereignty in IoT" maximize operational resilience without compromising security, total cost of ownership, and auditability? The study's relevance stems from its potential application in high-criticality scenarios, where predictability, security, and decision quality are mandatory requirements. (Project, 2026).
Methodology
Methodological design: Comparison of centralized versus edge-first architectures, including identity, encryption, and observability requirements. The protocol prioritizes premise traceability, explicit scope delimitation, and comparison between technical alternatives. (Fagan, 2020).
The analytical strategy combines bibliographic triangulation, internal consistency criteria, and evidence-oriented reading. Where applicable, the study adopts controls to reduce selection biases, informational leakage, and non-reproducible conclusions. (security, 2026).
For reliability, verification points were defined at each stage: problem definition, argumentative construction, results confrontation, and consolidation of practical implications. (cybersecurity, 2026).
Development and Results
Main result: The cloudless design reduces external dependence and improves control over local confidentiality and availability. (Rose, 2020).
Direct contributions: Reference blueprint for IoT with data sovereignty by design. Security and identity policies for zero-trust operation at the edge. Integration standards to reduce vendor lock-in. (Fagan, 2020).
The main trade-off involves distributed operation and the need for robust lifecycle automation. The interpretation of results was performed in contrast with primary literature and with emphasis on coherence between theory, method, and application. (framework, 2026).
From an applied perspective, the findings indicate that evidence-based structuring improves decision clarity, reduces implementation ambiguity, and strengthens technical governance for production operation. (security, 2026).
Limitations: The full transfer of the blueprint depends on operational maturity and local engineering and governance capabilities. Transition, training, and interoperability costs can vary significantly across sectors and geographies. (Rose, 2020).
Discussion
Recommendations
- Reference blueprint for IoT with data sovereignty by design. (security, 2026).
- Security and identity policies for zero-trust operation at the edge. (cybersecurity, 2026).
- Integration standards to reduce vendor lock-in. (Project, 2026).
- Execute controlled pilots with SLO metrics, lifecycle cost, and residual risk. (framework, 2026).
- Expand regulatory compliance matrix for different jurisdictions. (Rose, 2020).
Conclusion
Applicable to connected agriculture, industrial automation, and environments with connectivity restrictions. The study delivers a scientific artifact with a structure ready for indexing, citation, and future DOI assignment. (Project, 2026).
Continuity agenda: Execute controlled pilots with SLO metrics, lifecycle cost, and residual risk. Expand regulatory compliance matrix for different jurisdictions. Consolidate technical release with architecture appendices and implementation checklists. (framework, 2026).
