Servers · Infrastructure

Server configuration with security guarantee.

Design, installation and hardening of on-premise, cloud and hybrid infrastructure. Linux and Windows servers hardened under CIS Benchmarks and ISO 27001 controls. 24/7 monitoring and verified backups.

Four infrastructure domains

We cover the full cycle: from architecture to daily operation. We work with public cloud, on-premise and hybrid architectures.

On-premise · Data center
On-premise · Data center

Robust physical infrastructure.

Rack design, UPS and cooling sizing, Proxmox/VMware virtualization, NAS/SAN storage and Linux/Windows server hardening under CIS Benchmarks.

  • Proxmox · VMware · Hyper-V
  • Redundant NAS/SAN storage
  • UPS + cooling + rack
  • CIS Benchmarks hardening
Public and hybrid cloud
Public and hybrid cloud

Well-architected cloud.

Design and deployment on AWS, GCP, Azure, DigitalOcean, Contabo and Oracle Cloud. Infrastructure as code with Terraform and Ansible. Multi-region and multi-AZ for high availability.

  • AWS · GCP · Azure · DO · Oracle
  • IaC Terraform + Ansible
  • Multi-AZ / multi-region
  • FinOps: cost optimization
Security and hardening
Security and hardening

Professional hardening.

CIS Benchmarks, fail2ban, mandatory MFA, encryption at rest and in transit, centralized secret management, WAF and continuous vulnerability scanning. ISO 27001 aligned.

  • CIS Benchmarks + fail2ban
  • MFA + secret management (Vault)
  • LUKS / TLS 1.3 encryption
  • WAF + Nessus/Trivy scans

Diferenciación

How we differentiate

Infrastructure as code

All versioned in Git. Nothing done through console without trace. Reproducible rebuilds.

Living documentation

C4 diagrams, operational runbooks and ADRs per decision. Your team stays autonomous.

Optimized costs

FinOps applied: reservations, spot instances, auto-scaling and per-service spend monitoring.

Security by-default

CIS Benchmarks + MFA + fail2ban + at-rest encryption. Not optional, it's the baseline.

Metodología

How we work

From architecture to handover, with documentation and automation from day one.

  1. 01

    Assessment

    Current infrastructure inventory, risk analysis, requirements and target architecture.

  2. 02

    Design

    C4 diagrams, migration plan, sizing, budget and execution schedule.

  3. 03

    Provisioning

    IaC with Terraform/Ansible. All versioned in Git. Architecture documentation and operational runbooks.

  4. 04

    Handover

    Internal team training, credential transfer and reactive support for 30 days.

Frequently asked questions

Do you recommend on-prem, cloud or hybrid?

Depends on the case. We analyze total costs (TCO) over 3–5 years, regulatory requirements, latencies and team maturity. No vendor bias.

Do you provide 24/7 support?

Yes, with defined SLA plans. Rotating on-call with < 15 min response for critical incidents and < 4h for medium severity.

Can you migrate our existing servers?

Yes. We execute hot migrations when possible, with rollback plan and minimized maintenance window.

Do you work with Kubernetes?

Yes, but only when the case justifies it. Often docker-compose + Nginx is sufficient and more maintainable than K8s.
