Public Sector & Digital Government
We help public organizations modernize legacy systems, evaluate sovereign and hybrid cloud options, strengthen resilience and design technology environments around security, data control and long-term infrastructure choice.
Public administrations need to improve services while continuing to operate systems, processes and records that may have developed over decades.
Nubes Consulting helps government organizations modernize citizen services, administrative workflows, data exchange, identity and shared technology platforms while connecting new systems with the public infrastructure already in place.
We design for the environment public institutions actually operate in: multiple authorities, existing registries, strict data controls, long system lifecycles, public accountability and increasingly cross-border digital services.
Modernize the service and the administration behind it
A digital public service can look simple to the citizen while depending on many organizations and systems behind the screen.
Identity may come from one service. Evidence may belong to another administration. A case can require several internal departments. Notifications, signatures, registers, payments and archived documents may all use different shared platforms.
Simply replacing the paper form with a web form does not solve that complexity.
We help administrations redesign the technology around the complete service: from citizen or business interaction through administrative processing, data exchange and final decision.
Digitize the service, not the bureaucracy.
Where digital government is changing
Seven areas where architecture, interoperability and delivery decisions determine whether public services can change safely.
Modernize the administrative core without rebuilding every service at once
Many administrations operate procedure-management platforms that have accumulated years of rules, forms, integrations, documents and local exceptions. They may still work, but every change becomes expensive.
The modernization strategy should therefore depend on what already exists.
Public services should be designed to work beyond one organization
The traditional integration question is how to connect system A to system B. For digital government, that is too narrow.
Public bodies also need to agree who owns the process, what exchanged information means, which legal rules apply and how another administration can use it. The European Interoperability Framework therefore separates interoperability into four layers.
Stop making citizens become integration middleware
Citizens and businesses should not have to download a document from one authority simply to upload it to another authority that could obtain the same evidence digitally.
This is the principle behind the EU Once-Only Technical System. OOTS connects public authorities across Member States so official evidence can be exchanged, at the user’s request, as part of cross-border administrative procedures. It uses common European building blocks including electronic identity and eDelivery.
This architecture is useful beyond OOTS itself. A modern public-service platform should understand who owns authoritative information, how that information is requested, how consent or legal authority is established, how its meaning is preserved and how its use can be audited.
The goal is not to build one giant government database. It is to make trusted sources usable across services.
Move from accounts and passwords toward trusted digital identity
Identity is becoming a shared layer of European digital government.
The European Digital Identity Wallet will allow citizens and residents to identify themselves and hold or present electronic attestations and documents across public and private services. Member States are required to provide wallets by the end of 2026.
For public-sector architecture, this means preparing services for identity federation, wallet-based authentication, electronic attestations, signatures and seals, organizational representation, attribute verification and privacy-preserving data disclosure.
The EUDI Architecture and Reference Framework provides common protocols, formats and interfaces across wallet providers, issuers and relying parties.
In Spain, this also needs to coexist with existing national services such as Cl@ve, electronic certificates and other shared administration infrastructure.
The right approach is therefore not to replace existing identity with the Wallet. It is to design an identity layer where national and European trust services can coexist during the transition.
Technology ecosystem for digital public services
Public-sector modernization normally combines shared government services, commercial enterprise platforms, open-source technologies and custom applications.
Nubes Consulting does not push public administrations toward one platform. We evaluate the ecosystem around the service, the responsible authority and the operating model.
Reuse what already exists before building another government platform
European digital-government architecture increasingly favors reusable building blocks.
The Commission’s Digital Building Blocks include reusable capabilities such as eDelivery and eSignature, designed to help administrations build interoperable cross-border services. The Interoperable Europe Portal also provides shared solutions, architectures and guidance.
Before building a new capability, check whether a national or European shared service already provides it.
This principle is especially strong in Spain, where law explicitly supports the reuse of public-sector applications and common solutions between administrations.
That creates a different consulting question from commercial software development. Not simply what should we build, but what should we integrate, reuse, share or retire.
Treat sovereignty as an architecture decision, not a hosting label
European public-sector cloud decisions increasingly consider more than the physical location of data.
The Commission’s Cloud Sovereignty Framework evaluates strategic control, jurisdiction, data and AI sovereignty, operational control, supply chain, technological autonomy, security and compliance, and environmental sustainability.
Turn public data into infrastructure that can be safely reused
Public administrations produce some of the most valuable datasets in society.
But data becomes useful only when ownership, quality, metadata, semantics and access rules are clear.
We help design data platforms that support internal operations, cross-authority exchange, analytics, open data and controlled reuse. Common European Data Spaces now include public-administration areas such as legal data, the Once-Only Technical System and public procurement data.
A public-sector data platform may therefore need to support authoritative registers, metadata catalogues, open-data publication, APIs, semantic models, event exchange, access policies, lineage and audit.
Open data does not mean unmanaged data.
Use AI to reduce administrative work without hiding public accountability
AI can support document classification, translation, search, citizen assistance, knowledge retrieval, fraud and anomaly investigation, case triage, software development and internal productivity.
But public administration has a higher responsibility when automated systems affect people’s rights, access to services or administrative decisions.
The EU AI Act places additional obligations on public authorities using certain high-risk AI systems, including human oversight and, for relevant deployments, fundamental-rights impact assessment requirements. Transparency requirements under the AI Act also began applying in August 2026.
Spanish Law 40/2015 already recognizes automated administrative action and requires responsible bodies to be identified for specification, programming, maintenance, supervision, quality control and audit, as well as responsibility for appeals.
Automate the administrative work. Keep the authority, evidence and accountability visible.
A digital service is only digital if people can actually use it
Public services have a different accessibility obligation from commercial applications.
They must work for people with different abilities, devices, languages and levels of digital confidence.
The EU Web Accessibility Directive requires public-sector websites and mobile applications to be accessible, supported by harmonized standards and established accessibility practices.
The European Interoperability Framework goes further by treating user-centricity, inclusion, accessibility and multilingualism as principles of good European public services.
We therefore treat accessibility as part of service architecture and delivery, not a test added immediately before launch.
Design public services to last beyond one project or supplier
Eight principles that shape how we design, build and operate public-sector platforms.
European Digital Government Framework
Public-sector technology decisions in Europe sit inside a common EU baseline and a national implementation layer. Both shape architecture, identity, data and infrastructure choices.
Nubes Consulting uses applicable regulation and recognised frameworks as architecture and engineering inputs. Formal conformity, certification and legal interpretation remain with the administration and qualified specialists.
European Union
- Digital Decade 2030 — sets the overall direction toward digital public services and digital identity
- Interoperable Europe Act — makes cross-border interoperability and interoperability assessments part of public-sector technology governance
- European Interoperability Framework — provides legal, organizational, semantic and technical interoperability principles
- Single Digital Gateway and OOTS — implement cross-border online procedures and once-only evidence exchange
- eIDAS 2 and the EUDI Wallet — create the European architecture for digital identity, credentials and trust
- GDPR — governs personal-data processing and data-protection responsibilities
- NIS2 — adds cybersecurity governance requirements for covered public administrations
- AI Act — adds governance, transparency and human-control requirements according to AI risk
- Web Accessibility Directive — requires accessible public websites and mobile services
- Open Data Directive and the wider EU data framework — shape publication and reuse of public-sector information
- Common European Data Spaces — create trusted models for cross-sector data sharing and reuse
- Cloud Sovereignty Framework — provides measurable criteria for sovereign digital infrastructure procurement
- EU Open Source Strategy — promotes reuse, openness and European control of important digital technology
- eProcurement, eForms and eInvoicing — standardize important parts of public procurement and supplier interaction
The Digital Europe Programme also continues to fund public-sector adoption of AI, cybersecurity, advanced digital skills and shared digital capabilities, so the EU direction is not simply regulatory. It is also investment-led.
Spain
Legal and architectural baseline
- Ley 39/2015 — administrative procedure and electronic interaction with public administration
- Ley 40/2015 — electronic public-sector operation, data exchange, automated administrative action, interoperability and reuse
- Esquema Nacional de Seguridad (ENS) — security principles and minimum requirements for public-sector information systems, currently regulated through Real Decreto 311/2022
- Esquema Nacional de Interoperabilidad (ENI) — national interoperability framework covering organizational, semantic and technical interoperability and standards
- GDPR and LOPDGDD — personal-data and privacy requirements
Shared Spanish digital-government services
- Cl@ve — shared electronic identification
- Carpeta Ciudadana — citizen view across procedures, records and data held by administrations
- Red SARA — inter-administration communications infrastructure
- Plataforma de Intermediación de Datos — inter-administration data exchange
- Notific@ and DEHú — electronic notifications
- SIR — exchange of registry entries
- DIR3 — common directory of public organizations and units
- SIA — inventory of administrative procedures and services
- FACe — electronic invoicing with public administrations
A good Spanish public-service architecture should generally ask which of these common services can be integrated before creating another local equivalent. Carpeta Ciudadana is built around exactly that model, federating existing services rather than copying all administrative data into one central application.
Other EU Member States
EU rules create the common baseline. Each Member State then adds national identity, cybersecurity, archival, procurement, accessibility and public-administration requirements.
We assess those national requirements per engagement rather than claiming uniform country-by-country public-sector compliance expertise across the Union.
Design technology that can survive public procurement
Public technology choices are shaped not only by architecture but by procurement, framework agreements, contractual responsibilities and long operating lifecycles.
The EU is continuing to digitize procurement through eSubmission, eAccess, eInvoicing, ESPD, eCertis, eForms and common procurement data.
Procure capabilities and outcomes without creating unnecessary dependence on one implementation supplier.
That means defining data ownership, interfaces, documentation, portability, source-code rights where applicable, operational access, subcontractor dependencies, transition assistance and exit requirements.
Public-sector architecture and procurement should reinforce each other.
Modernize services in stages that administrations can actually adopt
A public-sector transformation has to change systems and often processes at the same time.
Understand the public service → Map authorities, data and systems → Simplify the process → Reuse shared capabilities → Design interoperability → Build coexistence → Migrate services → Measure and improve
The order matters. Do not start by choosing a new portal or workflow platform. Start by understanding the service and who is responsible for each part of it.
The target architecture should simplify the administration—not only modernize the technology underneath it.

Frequently Asked Questions
Does Nubes Consulting build citizen portals?
Yes. We can design and implement digital-service architecture, portals, APIs and integration with administrative platforms and national shared services.
We prefer to treat the portal as one part of the complete public service rather than the transformation itself.
Can you modernize legacy administrative systems?
Yes. We start by identifying procedures, integrations, records, data and dependencies before deciding whether a system should be refactored, replatformed, replaced or retained.
Do you work with Spanish public-administration shared services?
Our architecture can integrate with shared government capabilities such as identity, notifications, registries and interoperability services according to the relevant technical and organizational requirements.
Specific access and integration depend on the contracting authority and service.
Are you ENS certified?
Nubes Consulting designs infrastructure and engineering controls with ENS requirements in mind where they apply. We do not claim ENS certification unless the relevant Nubes Consulting service and scope has completed the formal conformity process.
Can public-sector systems use cloud?
Yes. The decision should depend on information classification, sovereignty, security, operational requirements and economics rather than a generic cloud-first or cloud-avoidance rule.
Public, sovereign, private and hybrid options can all be appropriate.
Do you recommend European sovereign cloud providers?
We can assess European and global providers according to the sovereignty level the service actually requires.
The decision should consider legal jurisdiction, data, operations, supply chain, technology, security, resilience and exitability.
Can you help with EUDI Wallet integration?
Yes, at the architecture and engineering level.
This can include identity flows, relying-party integration, attestations, APIs and coexistence with existing national identity systems.
How do you approach AI in government?
We prefer bounded, explainable uses with clear ownership.
AI can support staff and automate routine work, but decisions affecting citizens’ rights or access to public services require stronger evidence, human oversight and compliance controls.
Can you work with our existing systems integrators?
Yes. Public programs commonly involve platform vendors, framework suppliers, public IT organizations and specialist contractors.
Nubes Consulting can provide architecture and technical-delivery leadership across those boundaries.
