• Direct access to hardware resources allows you to achieve near-native performance. This is critical for high-performance applications and workloads that need consistent throughput.

• Server isolation and dedicated resources work together to provide a stable environment for your most demanding tasks.

Tip: If you need stable latency for live betting, streaming, or payment flows, dedicated servers with single-tenant architecture can help you avoid the instability often found in cloud environments.

Stability Advantages

Noisy Neighbor Elimination

You avoid the noisy neighbor effect when you choose dedicated servers. In cloud environments, multiple users share the same hardware. If one user consumes too many resources, your applications may slow down or become unstable. Dedicated servers solve this problem by giving you exclusive access to CPU, RAM, and storage. You never compete with other users for resources, so your high performance stays consistent.

The noisy neighbor syndrome originates from the sharing of common resources in some unfair way. In fact, in a world of finite resources, if someone takes more than licit, others will only get leftovers. This is arguably one of the main reasons for which many organizations prefer to avoid virtualizing their business-critical applications. Using bare metal instead of virtualized applications can address the noisy neighbor challenge at the host level. This is because bare metal servers are single tenant, with dedicated CPU and RAM resources.

You can see the impact of noisy neighbors in cloud servers by looking at real-world metrics:

You gain stability and reliability because your workloads never suffer from unpredictable slowdowns. Dedicated servers deliver high performance for every application, even during peak usage.
