VDS Operating System Selection Guide
A shared code base with the SUSE ecosystem, the YaST management tool and Btrfs snapshot support.
Network/firewall/package management with YaST and Btrfs snapper snapshots.
At the order step, choose the openSUSE Leap 15.6 template.
| Version | openSUSE Leap 15.6 |
|---|---|
| Base | SUSE Linux Enterprise |
| Package manager | zypper |
| Kernel | 6.4+ |
| Architecture | x86_64 |

| LTS / support | 15.6 lifecycle |
| Container | Podman, Docker CE |
The recommendations below are for general guidance; actual needs vary with traffic and application architecture.
| Use | Resources | Note |
|---|---|---|
| PostgreSQL / web | 2–4 vCPU · 4 GB RAM | Medium resources |
| SAP dev/test | 4+ vCPU · 8 GB+ RAM | SAP consumes RAM |
| cPanel | ✕ Not supported |
| Plesk | ◐ Partial / after installation |
| DirectAdmin | ✕ Not supported |
| Docker | ✓ Supported |
| Nginx | ✓ Supported |
| Apache | ✓ Supported |

openSUSE Leap 15.6 is a Linux distribution release published in 2024. Kernel/base: 6.4+. Default components: Btrfs snapshots, YaST, zypper, firewalld, systemd. In a VDS environment, openSUSE Leap 15.6 is delivered as a virtual machine with root/Administrator access and IPv4/IPv6 support, through SistemDC automatic provisioning or the KVM console. The support window means security patches are available into 2025+ (15.6 lifecycle), which makes hosting costs predictable. At the KVM hypervisor layer, dedicated vCPUs and NVMe I/O deliver consistent performance without noisy neighbours. On an openSUSE Leap 15.6 VDS, the hostname, SSH key and package updates can be automated with cloud-init (on supported templates) or the SistemDC post-install script. For disk I/O, keep the NVMe queue depth high; for PostgreSQL/MySQL the vm.swappiness=10 sysctl setting is recommended. Logrotate and journald prevent the disk from filling up. Monitoring: a lightweight setup with node_exporter + Prometheus or Netdata. If you use containers, after a zypper-based Docker/Podman installation run containers as non-root and define cgroup v2 limits. SistemDC's Istanbul POP delivers low jitter for traffic within Turkey, without carrier-grade NAT.
Choose openSUSE Leap 15.6 if…
Typical use cases for an openSUSE Leap 15.6 VDS: SAP HANA dev/test, PostgreSQL, SaltStack minions, Ceph storage nodes, Kubernetes (Rancher). Thanks to the Turkey location, local users get a fast TTFB with 5–15 ms ping domestically. On Ryzen VDS plans, high single-core GHz is preferred for game servers and Discord bot workloads. With SistemDC NVMe disks, random-I/O-heavy database queries see 5–10x lower latency than on an HDD VDS. Under heavy traffic the Stormwall DDoS filter kicks in automatically at the network layer. For CDN origin, reverse proxy caching and static asset delivery, optimise the Nginx/Apache configuration on openSUSE Leap 15.6 with HTTP/2 and Brotli compression; for users in Turkey, the origin location directly improves the SEO Core Web Vitals LCP score.
When ordering a SistemDC VDS, choose openSUSE Leap 15.6 as the template. After the first login, run zypper update && zypper upgrade -y to update the packages. Hostname: hostnamectl set-hostname server.yourdomain.com. Time zone: timedatectl set-timezone Europe/Istanbul. Create a new user with sudo privileges and disable root SSH login. Verify the network configuration (netplan/NetworkManager/ifcfg). On low-RAM plans you can add a 1–2 GB swapfile. Installing Fail2ban is recommended.
SSH hardening: /etc/ssh/sshd_config — set PermitRootLogin no, PasswordAuthentication no (use an ED25519 key), with an optional port change. firewalld: firewall-cmd --permanent --add-service=ssh, --add-service=http, --add-service=https, firewall-cmd --reload. Leave SELinux in enforcing mode; use semanage when opening custom ports. Updates: zypper update -y && zypper upgrade -y — automate with a weekly cron. KernelCare (optional) applies kernel patches without a reboot. SistemDC Stormwall network-layer DDoS protection is standard. SSH guide: Linux SSH Security.
A Linux VDS environment has no physical sleep/hibernate mode; the virtual machine is kept running continuously by the hypervisor (N/A). Power management is provided on the server side with 24/7 active uptime; systemd sleep targets are disabled in the server templates.
In the VDS order flow in the SistemDC client area, open the Operating System step and choose the openSUSE Leap 15.6 template. For general web/API, choose the Intel Xeon TR-VDS plans; for gaming, bots and high GHz, choose Ryzen VDS. For control panel installation, see our application setup guides for details. Category: VDS plans.
Leap vs Tumbleweed?
Leap is stable; Tumbleweed is rolling — use Leap in production.
Is YaST used on a VDS?
Yes; for network, firewall and package management.
Leap vs Tumbleweed VDS?
Leap is stable/LTS-like; Tumbleweed is a rolling release — use Leap in production.
SELinux on openSUSE?
AppArmor is the default; SELinux is not the default option.
What is the advantage of Btrfs snapshots?
A rollback point can be created with snapper before a system update.
