SLES / SUSE Linux Consulting

Zwiegnet delivers advanced SUSE Linux Enterprise Server (SLES) expertise — the enterprise-grade Linux distribution known for long support lifecycles (up to 13+ years), rock-solid stability, security certifications, and hybrid cloud readiness. We support all current SLES versions (15, 16) across bare metal, virtualized, and cloud environments, helping you run mission-critical, secure, and scalable infrastructures.

Our SLES consulting services include:

• Installation & Configuration – Fresh SLES deployments, YaST automation, repository & module setup, pattern/package management, and integration with existing infrastructure.
• Performance Tuning – Kernel parameter optimization, I/O scheduler tuning, CPU/NUMA balancing, memory management, and workload-specific adjustments for databases, SAP, or virtualization.
• Security Hardening – SELinux/AppArmor configuration, firewall (firewalld), auditd, FIPS 140-3/Common Criteria compliance, secure boot, and hardening for regulatory requirements (HIPAA, PCI-DSS, etc.).
• High Availability & Clustering – SUSE HA Extension setup, Pacemaker/Corosync clusters, SAP HANA System Replication, load balancing, fencing, and disaster recovery planning.
• Live Patching & Maintenance – Implementation of SUSE Live Patching (kernel updates without reboot), automated patch management, maintenance windows minimization, and long-term support (LTSS) guidance.
• Cloud & Hybrid Integration – SLES on AWS/Azure/GCP/OCI deployments, PAYG images, hybrid cloud migration, container support (Podman/Docker), and integration with Kubernetes/Rancher.
• SAP on SLES Optimization – SLES for SAP Applications tuning, Trento observability, HANA HA/DR setup, performance for SAP workloads, and best-practice alignment.
• Migration & Upgrade – SLES upgrades/service pack migrations, CentOS/RHEL to SLES transitions, legacy Unix to SLES, and minimal-downtime strategies.
• Monitoring & Logging – Integration with Prometheus, Grafana, rsyslog, SUSE Manager, observability setup, alerting, and compliance reporting.
• Troubleshooting & Break-Fix – Diagnosis of kernel panics, performance bottlenecks, hardware/driver issues, YaST failures, cluster split-brain, and production outage resolution.

SLES is built for the enterprise — long lifecycles, verifiable security, and freedom from vendor lock-in. We ensure your SLES environments are reliable, compliant, and optimized for any scale.
