Cheap VPS plans are everywhere. Cheap and actually-good plans are rarer. Here's the small list of things worth checking before you hand over a year of payment to save €3 a month.

1. Virtualisation type

You want KVM for almost any modern workload. OpenVZ and LXC have their place, but they share kernels, can be oversold harder, and limit what you can run (custom kernels, Docker-in-VM, full-disk encryption). If a plan doesn't say what virt it uses, assume it's the cheaper one.

2. Where the box physically sits

The marketing page may say “offshore”. The actual datacentre matters more. Look for:

3. Bandwidth math

“Unmetered 1 Gbps” on a $4 plan is rarely true unmetered — there's almost always a fair-use ceiling. Ask for the soft cap. A plan that admits to a 10 TB/month soft cap is more honest than one that promises infinity and shapes you to a crawl when you hit 2 TB.

4. Oversell ratio (the one nobody publishes)

Hosts always oversell to some degree. The sane question isn't “do you oversell” (yes, everyone does) but “by how much”. Two proxies you can use without insider knowledge:

  1. Look at trial reviews on independent forums (LowEndTalk, Reddit) for steady-state CPU steal.
  2. Buy the smallest plan first, run a month, then commit annually.

5. Support response time, on the channel you'll use

If you live in tickets, ticket-test them. Ask a pre-sales question and see how long the reply takes. The provider that answers in 4 minutes at sales will often answer in 4 minutes when your VM is offline at 2 AM.

Where to spend the savings

If you're going to economise, economise on RAM (you can usually upgrade later). Don't economise on the network — a VPS with 1 GB RAM and a clean 1 Gbps uplink will out-perform 4 GB on a congested 100 Mbps shared pipe for almost any web workload.
