Seintec vs Merlos: cloud infrastructure, ERP hosting and managed IT
Looking at Merlos, or shortlisting IT providers in Barcelona? We compare their published services with Seintec's and set out the options for cloud, servers, data centre, ERP hosting and cybersecurity.
This page is produced and published by Seintec Systems SL. Seintec and Merlos are independent companies.
What is the difference between Seintec and Merlos?
Seintec and Merlos are two technology providers based in the province of Barcelona. They overlap in several areas — managed IT, cloud, networking, backup and cybersecurity — but their published positioning is different.
Merlos presents its offer around business management software: an ERP with industry editions, CRM, business intelligence, automation and AI agents, unified communications and technical fit-out work, alongside IT and cloud services for SMEs.
Seintec specialises in the infrastructure layer: business cloud and servers running in its own data centre in Sant Miquel de Balenyà (Barcelona), virtual and dedicated servers, virtualisation, cloud desktops, backup, disaster recovery, monitoring, networking and managed security.
It is not always an either/or decision. The business application and the infrastructure it runs on can have different owners: where architecture, licensing and contracts allow, an ERP can stay with its specialist while running on Seintec infrastructure.

The absence of public information does not necessarily mean the provider lacks that capability.
Two different answers to the same question
How Merlos positions itself
According to its website, Merlos is a technology provider with an office in Badalona and more than 30 years in business, built around business management software and its ecosystem.
- ERP for SMEs with industry editions
- CRM and business intelligence
- Automation and AI agents
- Unified business communications
- IT, cloud and cybersecurity services for SMEs
- Technical fit-out: cabling, electrical, cooling, racks and server rooms
How Seintec positions itself
Seintec is a critical infrastructure provider: it designs, runs and maintains the layer your business applications sit on, from its own data centre in the province of Barcelona.
- Private and hybrid cloud with managed servers
- Virtual servers, VPS and dedicated servers
- Own data centre, housing and colocation
- Virtualisation, hyperconvergence and storage
- Backup, disaster recovery and business continuity
- Managed cybersecurity, SOC/MDR, networking and monitoring
The right choice depends on where the centre of gravity of your project sits: the management application, or the infrastructure underneath it.
Owned infrastructure
Infrastructure you are welcome to visit
Seintec runs its own data centre in Sant Miquel de Balenyà (Osona, Barcelona). It is not resold rack space: the facility, power, cooling, network and servers are designed and operated by the same team that handles your tickets.
Request a technical visitOver 150 m² of floor space
An owned server room with headroom to grow in compute and storage.
10 Gb/s fibre backbone
Uplink over the Xarxa Oberta de Catalunya with automatic failover to a high-capacity radio link.
Protected power
Uninterruptible power supplies and diesel generators.
High-efficiency cooling
Continuous thermal control of the technical room.
In-house operations centre
Continuous platform monitoring and a test lab to validate changes before production.
Data stays in Spain
The infrastructure is located on Spanish territory, under the GDPR framework.
From the data centre to the operating system
Owning the infrastructure means being able to work across several layers at once — when something breaks, and when an environment needs sizing. These are the layers Seintec can work on:
- 01Data centre
- 02Power
- 03Network
- 04Firewall
- 05Servers
- 06Storage
- 07Hypervisor
- 08Virtual machine
- 09Windows / Linux
- 10SQL
- 11ERP
- 12End user
The fact that Seintec works across these layers implies no assessment of any other provider's capabilities.
Engineers who also understand what sits below the virtual machine
When the problem is not in the application, you need people who can read the hardware. Seintec's team works day to day with the components that decide how a business environment actually performs.
Written for CTOs, CIOs, IT managers, systems leads and SME owners.
Your ERP and your infrastructure can have different owners
In many companies the firm that maintains the ERP also hosts the servers. That is a valid model, but not the only one: these are two distinct technical layers and they can be contracted separately where architecture and agreements allow.
ERP / application layer
ERP provider: Merlos or another specialist
- Application and licensing
- Configuration and parameterisation
- Functional consultancy
- Version upgrades
- End-user training
- Day-to-day functional support
Infrastructure layer
Seintec
- Physical or virtual servers
- Windows Server and SQL Server
- Virtualisation and storage
- CPU, RAM, IOPS and sizing
- Network, VPN and firewall
- Backup, security and monitoring
Does Merlos manage your ERP? You can review the infrastructure separately
If Merlos — or any other specialist — manages or supervises your ERP, you can assess independently where and how the underlying infrastructure runs.
Where technical, licensing and contractual requirements allow, Seintec can provide that infrastructure while your ERP provider keeps working on the application: servers, virtualisation, storage, network, firewall, backup, monitoring and continuity.
Choosing Seintec for infrastructure does not necessarily mean changing ERP provider.
Seintec and Merlos are independent companies. This technical possibility does not imply any agreement, collaboration, partnership, sponsorship or endorsement between them.
- The ERP architecture allows it
- Licensing allows it
- Current contracts allow it
- It is technically compatible
- The ERP provider can work on third-party infrastructure
This must be validated case by case.
What separating responsibilities can bring
Specialisation by layer
Each provider can concentrate on its own domain: the application on one side, the infrastructure on the other.
Flexibility
Infrastructure can evolve without forcing a change of business application.
Scalability
CPU, RAM and storage can be adjusted as user numbers or data volumes change.
Backup
Allows a protection strategy designed specifically for the infrastructure and its data.
Security
Makes it easier to apply controls across network, perimeter and servers in a coordinated way.
Continuity
Enables a disaster recovery plan to be designed where the business needs one.
When the ERP feels slow, the ERP is not always the cause
Perceived slowness can originate in very different layers. Before touching the application, it pays to measure where the time is actually going.
Every environment differs: this lists possible causes, not a diagnosis of any specific case.
Request an ERP infrastructure reviewSQL Server and ERP performance
Many ERP products rely on a relational database, and in Windows environments SQL Server is common. Where that is the case, database behaviour shapes the experience users get.
- Memory assigned to the instance and contention with the operating system
- Available cores and parallel execution plans
- IOPS and latency across data, log and tempdb volumes
- Concurrency, blocking and wait statistics
- Indexes, statistics and routine maintenance
- Separating application and database workloads
- Maintenance and backup windows
Not every ERP uses SQL Server: any analysis starts from the database engine actually in use.
Running an ERP over Remote Desktop
Where the ERP is published through Remote Desktop Services or RemoteApp, service quality depends on the server and on the user session alike.
- Sizing RDS hosts and concurrent sessions
- User profiles and profile storage
- Remote printing and device redirection
- Integration with Microsoft 365 and corporate file shares
- Secure access: VPN, controlled publishing and MFA
- Remote Desktop access licensing
Protecting an ERP takes more than one layer
Protecting an ERP is not simply copying a folder. Depending on the environment, the strategy can combine several levels of backup and recovery.
- Backup of the application and its configuration
- Consistent database backup
- Full virtual machine backup
- Off-site copy away from the primary location
- Retention policy aligned with applicable regulation
- Immutable copies where the platform supports them
- Regular restore testing
- A disaster recovery plan where the business case justifies it
There is no single strategy that fits every company: it depends on the RPO and RTO each business needs.
What server does your ERP need?
Correct sizing does not come from a catalogue — it comes from measuring how the system is really used. These are the factors we look at.
- Number of concurrent users
- ERP product and database engine in use
- Database size and growth rate
- Concurrency at month-end, stocktakes or seasonal peaks
- Remote Desktop versus installed client
- Integrations with web, EDI, logistics or manufacturing
- Associated document volumes
- Three-year growth outlook

Frequently asked questions
- What is the difference between Seintec and Merlos?
- Based on what both companies publish, Merlos positions itself around business management software — ERP, CRM, business intelligence, automation and AI — alongside IT, cloud, cybersecurity and technical fit-out services. Seintec specialises in infrastructure: business cloud and servers in its own data centre in the province of Barcelona, virtualisation, backup, disaster recovery, networking and managed security. Some areas overlap and some are specific to each.
- Can I keep my ERP with Merlos and host it with Seintec?
- It is a viable architecture where the ERP, its licensing and the contracts in force allow it, and where the ERP provider can work on third-party infrastructure. Seintec takes the infrastructure layer and the specialist continues with the application. It must be validated case by case; Seintec and Merlos are independent companies and this possibility implies no agreement between them.
- Can I migrate my ERP to the cloud?
- Usually yes, either by migrating the whole server or by installing the ERP on a new virtual machine. The critical part is not copying the data but sizing, the downtime window, user access and performance testing beforehand.
- Does Seintec have a data centre in Barcelona?
- Yes. Seintec operates its own data centre in the province of Barcelona, in Sant Miquel de Balenyà, with over 150 m² of floor space, a 10 Gb/s fibre backbone with radio-link failover, UPS systems, generators and an in-house operations centre.
