Short answer: a VPS is enough until you need either more than about 8-16 vCPUs and 32 GB of RAM in one machine, steady 100% CPU load around the clock, guaranteed disk throughput for a large database, or full control of the hardware (GPU, licensing per physical socket, compliance). Below those thresholds a VPS is cheaper, faster to change and easier to move. As of October 21, 2026 a 4 vCPU / 8 GB VPS costs from about $19-22 a month in our catalog.
What you actually get with each
A VPS is a slice of a physical server: guaranteed memory, a share of CPU cores and disk, your own operating system. A dedicated server is the whole machine. The difference is not speed as such, it is predictability: on a VPS your neighbours share the CPU and the disk, on a dedicated server nobody does.
Five signs a VPS is no longer enough
- The CPU is busy all the time. A VPS core is usually shared. If your load sits near 100% for hours (video encoding, compiling, a busy game server), you pay for steal time you cannot see. A plan with dedicated vCPUs fixes this before a dedicated server does.
- The database does not fit in memory. When the working set of PostgreSQL or MySQL exceeds 32-64 GB, large VPS plans get expensive fast, and a dedicated server with 128 GB is often cheaper per gigabyte.
- Disk latency matters more than capacity. Local NVMe on your own hardware gives steady latency under heavy writes; shared storage on a VPS can vary at peak hours.
- You need specific hardware. GPUs for training, many cores for licensing per physical socket, or hardware-level isolation for compliance.
- Traffic is huge and steady. Dedicated servers often come with unmetered ports, while VPS plans cap or bill egress.
When a VPS is the better choice
For a website, a store, a bot, n8n, a staging environment or a small database, a VPS wins on every count: it is cheaper, it resizes in minutes, snapshots are built in, and you can move to another region the same day. Most projects never cross the thresholds above.
The money
A 4 vCPU / 8 GB VPS runs about $19-22 a month at the cheapest providers in our catalog (MassiveGRID and Hostman as of October 21, 2026). Doubling to 8 vCPUs and 16 GB roughly doubles that ($48 a month at Hostman). A dedicated server does not resize without a migration, so compare it with the VPS plan you will need in a year, not today. It starts to pay off when you are on the largest VPS plans or need hardware a VPS cannot give.
What to do
Start on a VPS sized for today's load and watch three numbers for a month: CPU steal time, memory headroom and disk latency at peak. Move to dedicated vCPUs first, and to a dedicated server only when those numbers say so. The calculator finds VPS plans for a given configuration, and the database page and game server page list plans for the heavier jobs.
