What is a dedicated server? When to choose it
What is a dedicated server?
A dedicated server is a single, physical machine reserved exclusively for one customer. Unlike shared hosting or virtual private servers (VPS), where many tenants share the same hardware, a dedicated server provides you with full access to all CPU cores, memory, storage and network resources. There is no virtualization layer between your operating system and the hardware, which means predictable performance and the freedom to customise the environment for your workloads.
**Advantages of dedicated servers:**
- **Guaranteed resources:** All hardware (CPU, RAM, NVMe SSD/HDD storage and network port) is allocated to you and not shared with other customers. This delivers consistent performance for demanding applications and low‑latency workloads.
- **Full control:** You can choose the operating system (Linux, Windows or custom ISO), partition disks, install kernel modules and configure software exactly as needed. There are no restrictions imposed by a hypervisor or shared host.
- **Enhanced security:** Being the only tenant on the machine eliminates the risk of noisy neighbours or cross‑tenant vulnerabilities. You can implement strict firewall rules, encryption and compliance measures tailored to your requirements.
- **Scalability:** Dedicated servers can be scaled vertically (upgrade RAM, add disks, upgrade port speed) and horizontally by deploying multiple machines in a cluster or private network.
### When to choose a dedicated server
You should consider a dedicated server when:
- **High‑performance needs:** Your application demands low latency and high throughput, such as game servers, real‑time communications, databases, big‑data analytics or video streaming.
- **Complete control is required:** You need to run custom or proprietary software, modify kernel parameters, or use operating systems unsupported by container or VPS platforms.
- **Large resource requirements:** Your workload requires more CPU cores, RAM, or I/O than a VPS can provide (e.g., 16+ cores, 64 GiB+ RAM).
- **Regulatory or compliance needs:** Certain industries mandate physical isolation and dedicated hardware for security and certification.
- **Virtualisation host:** You plan to host virtual machines or containers for your own customers or internal services and need a hypervisor platform with full root control.
