Introduction
The main mistake when buying a VPS is overpaying for unused resources or, conversely, saving money in a way that makes your project crawl. Let's break down how to choose a configuration deliberately and not pay extra.
Key parameters
CPU (vCPU). One virtual core handles a landing page or a personal VPN. Two or more are needed for databases, project builds, and game servers. Mind the type: honest providers list dedicated cores, not "shares" (shared vCPU).
Memory (RAM). The minimum for comfortable server operation is 1 GB. For a WordPress site with caching — 2 GB. For databases, development environments, and containerization — from 4 GB.
Disk. Capacity is secondary; the type is what matters:
- NVMe — the fastest, ideal for databases and high-load sites;
- SSD — the best price/speed balance;
- HDD — only for archives and backups.
Bandwidth and traffic. Pay attention to included traffic: unlimited at 100 Mbit/s and 1 TB at 1 Gbit/s are different things.
Analysis: configurations for typical tasks
| Task | vCPU | RAM | Disk | Approximate budget |
|---|---|---|---|---|
| Personal VPN server (1–5 devices) | 1 | 1 GB | 10–20 GB | $3–5/mo |
| Landing page / blog | 1 | 1–2 GB | 20 GB | $4–8/mo |
| CMS e-commerce store | 2 | 2–4 GB | 40 GB | $10–20/mo |
| Database + backend | 2–4 | 4–8 GB | 80+ GB | $25–60/mo |
| Game server | 2–4 | 4–8 GB | 50+ GB | $20–40/mo |
Analysis conclusion. The "better more than less" rule works poorly in the VPS world: upgrading a plan at most providers takes a couple of minutes without reinstalling. So start with the minimum sufficient configuration and add resources as load grows. On the other hand, you shouldn't skimp on disk type: switching from NVMe to HDD feels like a several-fold degradation.
Bottom line
Define the task, take the minimum suitable plan, and watch the metrics. A well-chosen VPS is not "maximum hardware" but an exact match between resources and load.
