Cloud Computing for Enterprises in Spain

What Is Cloud Computing?

Cloud computing is the delivery of computing services — including servers, storage, databases, networking, software, analytics, and artificial intelligence — over the internet (“the cloud”). Instead of owning and operating physical servers or data centres, businesses access these resources from cloud providers on a pay-per-use or subscription basis.

The key distinction from traditional IT infrastructure:

• Traditional (on-premise): The company owns or leases hardware and software, maintains it in its own premises or a rented data centre, and bears the full capital and operational cost
• Cloud: The provider owns and maintains the infrastructure; the company pays for what it uses, scales up or down as needed, and accesses services from anywhere with an internet connection

Cloud Service Models

SaaS — Software as a Service

The most common cloud model for Spanish SMEs. The provider manages the entire stack (infrastructure, platform, and software); the customer simply accesses the application via a browser or client.

Examples: Google Workspace, Microsoft 365, Salesforce, Holded (Spanish ERP), Sage Cloud, Hubspot, Zoom, Factorial (Spanish HR software).

Who benefits most: All businesses, regardless of size. SaaS eliminates hardware costs, software updates, and maintenance, reducing IT complexity to near zero for standard business applications.

PaaS — Platform as a Service

The provider manages the infrastructure and operating system; the customer manages their own applications built on the platform.

Examples: Google App Engine, Microsoft Azure App Service, Heroku.

Who benefits most: Software development companies and technical teams building custom applications.

IaaS — Infrastructure as a Service

The provider manages the physical infrastructure; the customer manages the operating system, middleware, and applications.

Examples: Amazon Web Services (AWS) EC2, Microsoft Azure Virtual Machines, Google Compute Engine.

Who benefits most: Large enterprises and technology companies needing maximum control over their infrastructure configuration; companies migrating specific workloads from on-premise servers.

Cloud Deployment Models

• Public cloud: Infrastructure shared among multiple customers on the same physical hardware (logically isolated). Most cost-efficient; used for the majority of business applications.
• Private cloud: Dedicated infrastructure for a single organisation. Higher cost; used for highly sensitive data or workloads with specific regulatory requirements.
• Hybrid cloud: A combination of public and private cloud. Some workloads in public cloud; sensitive data and systems in private cloud.
• Multi-cloud: Using services from multiple cloud providers (AWS + Azure + Google Cloud) to avoid vendor lock-in or optimise for specific capabilities.

Cloud Computing and GDPR in Spain

The GDPR imposes important requirements on cloud adoption that Spanish businesses must navigate:

Data Processor Agreements (Contratos de Encargado del Tratamiento)

When a cloud provider processes personal data on behalf of a Spanish company, the company is the data controller and the cloud provider is the data processor (encargado del tratamiento). GDPR Article 28 requires a written data processing agreement (DPA) specifying:

• The nature and purpose of the processing
• The type of personal data and categories of data subjects
• The provider’s security obligations
• Conditions for engaging sub-processors
• Return or deletion of data upon termination

All major cloud providers (AWS, Azure, Google Cloud, Microsoft 365, Salesforce, etc.) offer standard GDPR-compliant DPAs.

Data Transfers Outside the EU/EEA

Most major cloud providers are US companies. Transferring personal data to servers outside the EU/EEA requires a legal basis:

• Adequacy decision: Transfer to countries the EU Commission has approved as providing adequate data protection
• Standard Contractual Clauses (SCCs): EU-approved contract terms that govern data transfers to non-adequate countries (including the US, in most cases)
• Binding Corporate Rules (BCRs): For intragroup transfers within a multinational

US-based cloud providers typically rely on SCCs (and in some cases the EU-US Data Privacy Framework) for EU data transfers.

Data Residency

Some Spanish companies — particularly in regulated sectors (banking, public administration, healthcare) or with specific data sovereignty requirements — require their data to be stored on servers physically located in the EU. All major cloud providers offer EU data residency options (AWS EU regions include Frankfurt, Ireland, Paris, Stockholm; Azure has data centres in Ireland and Netherlands; Google Cloud has data centres across the EU).

ENS (Esquema Nacional de Seguridad) for Public Sector

Cloud providers supplying services to Spanish public administrations must have ENS certification (from CCN-CERT). Several major providers (Microsoft, AWS, Google) have obtained ENS certification for their Spanish public sector offerings.

Security in the Cloud: The Shared Responsibility Model

Cloud security operates on a shared responsibility model:

A frequent security mistake is assuming the cloud provider is responsible for everything. The provider secures the infrastructure; the customer is responsible for securing their data, access controls, and application configuration.

Key Cloud Security Controls for Spanish Businesses

• Multi-factor authentication (MFA): Mandatory for all cloud accounts. Most cloud account compromises exploit weak passwords without MFA.
• Principle of least privilege: Users and systems only have access to what they need
• Encryption: Encrypt data at rest and in transit (most providers enable this by default; verify your configuration)
• Backup: Cloud data must still be backed up — cloud providers protect infrastructure availability, not necessarily data integrity (accidental deletion or ransomware can affect cloud data)
• Security monitoring: Enable cloud provider logging (AWS CloudTrail, Azure Monitor, Google Cloud Audit Logs) and review for anomalous activity

Cloud Computing and Business Continuity

Cloud adoption significantly improves business continuity compared to traditional on-premise infrastructure:

• Geographic redundancy: Data replicated across multiple data centres automatically
• Disaster recovery: Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO) measured in minutes rather than hours or days
• High availability: Cloud providers offer 99.9%–99.99% uptime SLAs for core services
• Remote access: Work continues from anywhere during office disruptions

See the bcp-drp entry for a detailed discussion of business continuity planning.

Main Cloud Providers in the Spanish Market

Spanish-specific SaaS providers (Holded, Factorial, Redbooth, Filestage) offer products designed for the Spanish regulatory environment (IRPF, Social Security, Spanish invoicing formats).

Frequently Asked Questions

Is cloud computing safe for sensitive business data under Spanish law? Yes, with appropriate configurations and contractual protections. GDPR compliance requires a signed DPA with the provider, appropriate security settings, and attention to data transfer mechanisms. Most major cloud providers support GDPR compliance and provide tools to configure data residency and access controls appropriately.

Does the Kit Digital programme fund cloud adoption? Yes. The Kit Digital programme includes categories for “virtual office and remote working tools” and “processes and administration management” that cover cloud-based collaboration and ERP platforms. Eligible businesses can receive grants of up to EUR 12,000 for qualifying cloud software subscriptions.

What is the difference between cloud backup and cloud storage? Cloud storage (Google Drive, Dropbox, OneDrive) is for active file access and collaboration — it is not a backup solution. Accidental deletion or ransomware can propagate to cloud storage. Cloud backup solutions (Veeam Cloud, Acronis Cloud, Backblaze B2) are designed specifically for backup and recovery with versioning and point-in-time restoration.

How do Spanish companies typically manage the transition from on-premise to cloud? The most common migration path: start with SaaS tools (email, productivity) which require no infrastructure migration; migrate file storage and backup next; then assess server workloads for cloud migration (IaaS) or replacement with SaaS alternatives. Most Spanish SMEs find that 80%+ of their on-premise workloads can be replaced by SaaS, eliminating the need for any IaaS migration.

What happens to data when a cloud provider goes out of business or terminates a service? Cloud providers typically provide a data export period before service termination. However, the risk of vendor lock-in (difficulty exporting data) is real for some platforms. Best practice: ensure you can always export your data in standard formats, maintain your own copies of critical data, and include data portability provisions in cloud contracts.
