Archive / VPS / Docker
If you are deploying Docker on a budget VPS, the real constraint is usually memory and operational headroom, not theoretical CPU power. The right plan is the one that still feels boring after containers, updates, logs, and one extra service inevitably get added.
For small Docker projects, a 2 vCPU / 4GB VPS is the practical default. It gives you enough room to run a reverse proxy, one or two application containers, and routine operational tasks without immediately fighting the box.
| VPS size | Best fit | Verdict |
|---|---|---|
| 1 vCPU / 2GB | Tests, toy projects | Cheap, but easy to outgrow |
| 2 vCPU / 4GB | Most single-host Docker deployments | Best default |
| 4 vCPU / 8GB | Multiple services, heavier stacks | Upgrade when you know why |
Containers are not free. You still need memory for the host OS, logging, networking, and the tendency for every useful project to become two or three services over time.
Direct rule
If your stack already includes a database, a reverse proxy, and one application service, do not pretend 2GB is a comfortable long-term answer.
It can be enough for testing, but 4GB is the safer baseline for a practical small Docker deployment.
Memory headroom matters most early. CPU matters too, but RAM is usually the first practical limit.
If you need Docker at all, you already need VPS-level control rather than managed WordPress hosting.
