Picking a VPS plan often comes down to guessing, then upgrading later once something feels slow. Here's a more direct way to think about it.
Start with the workload, not the specs
A small personal website or API endpoint rarely needs more than 1–2 cores and 1–2 GB of RAM. A production database, a busy CMS with plugins, or a small SaaS backend usually wants 4 cores and 4 GB or more, particularly under concurrent traffic.
Work out which resource actually runs out first
Four things can be the bottleneck and they have different answers. High load with an idle disk means CPU. Swapping or out-of-memory messages mean memory. High I/O wait means storage. If none of those is happening, the bottleneck is in your application — and a bigger plan will not move it. The symptoms and the plan that answers each are here.
Storage speed usually beats core count
For most web workloads, a two-core plan on fast storage will beat a four-core plan on HDD, because a database-backed page load is many small disk reads rather than heavy computation. Buy cores once you have measured that CPU is what you are waiting on.
Dedicated IPv4
One dedicated IPv4 address is included on every plan, which matters if you're running a mail server, want SSL bound to your own address, or want firewall rules scoped to a server nobody else shares. Additional addresses are available, subject to what the datacenter has.
Start smaller than you think
Moving to a larger plan is a supported change, so it is usually cheaper to start with what matches your current traffic and scale when you actually need to, rather than paying every month for headroom you may never touch. A first order also carries a 7-day money-back guarantee, so the cost of guessing slightly wrong is low.
