Solution & enterprise architecture
Turning business requirements into a technical design — target architecture, option assessment, technology selection and the documentation to support decisions and delivery.
Solution Architect · Infrastructure Consultant
Marek Haluška
I design and modernise server infrastructure with a focus on reliability, scalability and security — from enterprise on-premises environments to hybrid cloud. Since 2006 I've worked in infrastructure, automation and systems management at IBM, Kyndryl and Analytics Data Factory.
Services
Cloud & hybrid infrastructure
Target architecture, capacity plan, network and storage design, security requirements and a migration roadmap — for on-premises, cloud and hybrid environments.
Container platforms & GitOps
Production Kubernetes platforms with GitOps delivery, container registry and persistent storage — from design to operational handover.
Infrastructure automation
Automating repetitive administration across large Linux/UNIX estates — less manual work, fewer errors and faster, repeatable change delivery.
Monitoring & observability
Prometheus, Zabbix and Graylog — monitoring and centralised logging that shorten detection times and help resolve problems before they seriously affect users.
Security & identity
Vulnerability scanning with OpenVAS and Trivy, centralised identity with FreeIPA and Keycloak — visibility of risks and unified access control.
VMware to Proxmox VE migration
Moving away from VMware? I plan and execute migrations from vSphere to Proxmox VE — from assessment and sizing through storage and network design to a documented cutover.
