Dedicated server or VDS? The decision criteria

You cannot make this decision by asking "which one is more powerful", because the answer is always the dedicated server and that piece of information is useless. The right question is: which limit do you hit first?

Three limits

1. The single-core performance limit. If your workload is bound to one thread (FiveM, Minecraft, Rust, a single channel in Metin2) and you have filled that core, the last thing you can do on a VDS is upgrade the processor family. Once you have done that too, a dedicated server is the only route.

2. The total resource limit. If you need 64 GB of RAM or 16+ cores, you have reached the top end of the VDS plans and a dedicated server usually works out better on unit cost.

3. The storage volume and I/O limit. If you have hundreds of GB of data and a continuous write load (a large database, a multi-channel game server, a backup store), owning the whole physical disk widens the difference.

If you have not hit any of the three, VDS is the right choice.

Comparison

	VDS	Dedicated server
Resources	Reserved but virtual	The entire hardware
Scaling	From the panel within minutes	A new machine, with a lead time
Monthly cost	Low starting point	High baseline
Unit cost	Rises at high resource levels	Falls at high resource levels
Setup fee	None	Usually applies
Hardware failure	Can be moved to another machine	Requires a part replacement

The cost crossover point

A VDS's unit cost rises as resources grow, while a dedicated server's falls because it spreads over a fixed baseline. In practice the crossover sits around 32 GB of RAM and 12-16 vCPU: below that level a VDS makes more sense, above it a dedicated server.

But the decision is not only about price. On a dedicated server a hardware failure is your waiting time; on a VDS the service can be moved to another machine. For a project whose growth cannot be predicted, the flexibility of a VDS is a measurable value.

An intermediate step: more than one VDS

There is a step that is often skipped before moving to a single large machine: splitting the work. Moving the database onto a separate VDS is often more effective than growing the resources of one machine — because the bottleneck is usually not total resources but two different workloads sharing the same disk and the same memory.

Practical thresholds: 4 channels or 700-800 players in Metin2, 200-250 concurrent players on alt:V, and the point where Knight Online's MSSQL has to move to the full edition.

How this works at Datafex

On virtual server plans resources are reserved and there is no overselling; resource upgrades are requested from the panel. On dedicated servers the entire hardware is yours, and stock status and the monthly net price are shown on the page. Both are hosted in the DGN Data Centre in Bursa and Fexwall DDoS protection is included.
