Your on-premise infrastructure carries a hidden cost: maintenance, obsolescence and continuity risks. We migrate your servers, applications and data to the public or hybrid cloud — Azure, AWS or Google Cloud — with a phased plan that keeps your operations running without interruption.
Many Spanish SMEs are still paying for ageing physical servers that consume energy and require technical staff to maintain them. When hardware fails or an ERP upgrade is needed, the bill is unpredictable. Cloud migration converts that variable, uncertain expenditure into a predictable subscription model with built-in high availability and automatic backups. According to the IDC European Cloud Market 2025 report, more than 60% of European SMEs already run at least one critical workload on public cloud; those that have not yet migrated face a growing gap in security and costs compared to competitors who have.
At Summum Sistemas we have been supporting industrial companies, distributors, professional firms and service SMEs in Castilla y León and the Canary Islands since 2007. We know the ERP systems they use — Sage, Holded, Odoo, Dynamics — the integrations with e-commerce platforms and the compliance requirements that determine where and how data is hosted. We do not sell generic cloud: we design the architecture that fits your business, carry out the migration within agreed maintenance windows and train your team to operate independently in the new environment. The typical outcome is faster system response times, freedom from physical server dependency and simpler business continuity planning.
Security and regulatory compliance are built into the design from day one. Depending on your sector, we apply controls aligned with the National Security Framework (ENS), ISO 27001 or GDPR requirements for data in the cloud — including EU-based server location where the business requires it. If you also need to incorporate ISO 27017 or ISO 27018 controls into the scope of your ISO 27001 certification — covering cloud-specific security or the protection of personal data in the cloud — our Quality division can support you through that process in a coordinated way.
We inventory your servers, applications, dependencies and data volumes. We define what moves to the public cloud, what stays on-premise and how both environments connect. We deliver a report with the target architecture and a phased migration plan.
We provision the cloud environment in Azure, AWS or Google Cloud, replicate workloads and validate performance before routing real traffic. We identify and resolve version, licensing or connectivity incompatibilities without affecting your current production environment.
We carry out the final cut-over in an agreed window — typically outside business hours — with a documented rollback protocol. We verify data integrity, the correct functioning of each application and automatic backups before signing off the migration.
We monitor the environment during the first few weeks to detect performance anomalies or unexpected costs. We right-size resources so you pay only for what you consume, and we train your internal team in basic management of the new environment.
The operational detail: what we deliver as part of the work and what we keep alive afterwards.
Server and virtual machine migration
Migration of physical or virtual servers (VMware, Hyper-V) to equivalent cloud instances, with performance validation before the final cut-over.
ERP and database migration
Experience with Sage, Holded, Odoo, Dynamics and SQL Server, MySQL and PostgreSQL databases. We manage licences, connection strings and vendor-specific configurations.
Hybrid architecture (on-premise + cloud)
Design of mixed environments where part of the infrastructure stays local — for latency, regulatory or cost reasons — and the rest runs in the cloud, securely connected via VPN or ExpressRoute/Direct Connect.
Security and regulatory compliance
Configuration of identity services (Azure AD / Entra ID), encryption in transit and at rest, least-privilege access policies and EU data residency. Alignment with ENS, GDPR and ISO 27001 based on the company's profile.
Backup, recovery and high availability
Definition of automatic backup policies, Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO), and documented periodic restoration tests.
Cloud cost optimisation and governance
Resource right-sizing review, use of reserved or spot instances based on workload profile, spending alerts and a consumption dashboard so the client controls their monthly bill.
Cloud migration connects with Summum Sistemas' process automation, managed security and Microsoft 365 productivity capabilities, and opens the door to deploying Summum IA agents on top of data already centralised in the cloud.
Once in the cloud, Microsoft 365 integrates natively with Azure: single identity, collaboration and productivity tools built on the same infrastructure you have just migrated.

View service → iaWith data and applications already in the cloud, deploying automation flows and AI on top of them is simpler and more secure: Summum IA can build data pipelines and agents on the environment we have migrated.
View service →It depends on the number of servers, applications and data volume. A typical environment of 10–50 users with an ERP, file server and email can be migrated in 6–12 weeks, including the parallel testing phase. More complex projects — with multiple integrations or very high availability requirements — can take 3 to 6 months. During the initial diagnosis we establish a realistic timeline and include it in the plan delivered to the client.
There is no single answer. Azure is the most common choice when the company already uses Microsoft 365 or Dynamics, because identity and tooling integration is native. AWS offers the broadest service catalogue and is a strong option when the company has custom-built applications that consume platform services. Google Cloud excels for analytics and machine learning workloads. In all cases, we evaluate data centre distribution within the EU to ensure data residency in line with GDPR.
The migration plan always includes a documented rollback protocol established before the final cut-over is executed. Critical workloads are migrated in agreed windows — weekends or outside business hours — and the legacy environment remains operational until the new one is validated. In high-criticality cases, we keep both environments running in parallel for a coexistence period to catch any anomaly before switching off the local systems.
Yes. Hybrid architecture is a common solution when, for latency, cost or regulatory reasons, some systems must stay local. We design the secure connectivity between both environments — VPN, Azure ExpressRoute or AWS Direct Connect — and define which workloads go to the cloud and which stay, with documented technical and economic criteria.
Migration to cloud infrastructure can fall within the 'Cybersecurity' and 'Process Management' solutions of the Kit Digital programme, depending on the scope. For larger companies or more complex projects, Kit Consulting can fund the strategic consulting phase. We assess your situation and advise on the best fit before starting the process.
