Choose shared hosting when one site with steady, modest traffic needs nothing beyond PHP, a database and email. Choose a VPS when you need root access, your own software stack, or resources that are reserved for you alone. Choose a dedicated server when a share of one machine is no longer enough. Price comes last.
That is the whole answer, and most sites belong in the first group for years. The rest of this post is about the cases where the one-line version is wrong: the site that is small but spiky, the application that needs a process shared hosting will not run, and the developer who wants root access before there is any reason to have it. It also covers the tier between shared and VPS that most comparisons leave out, which is where a surprising number of "I need a VPS" conversations should actually end.
What Actually Separates the Tiers
Every tier is the same hardware. A shared account, a VPS and a dedicated server can all sit in the same rack, on the same model of machine, behind the same switch. What changes is how much of that machine is yours and who is responsible for keeping it running.
On shared hosting, one operating system serves hundreds of accounts. You get a home directory, a web server configuration you do not control, PHP and MySQL at versions the host chooses, and a control panel to manage all of it. The host patches the operating system, tunes the web server and restarts services when they need it. You never see a command prompt, and you never need one.
A VPS is a slice of a machine with its own operating system. Whether that slice is a container or a full virtual machine, which is the OpenVZ or KVM question, you get root, your own package manager, and a fixed allocation of cores, memory and disk that no other customer on the host can consume. You also get the job of running it.
A dedicated server is the whole machine. Every core, every gigabyte of memory, the disks and the network port. There is no hypervisor between you and the hardware, and there is no neighbor at all.
Shared is a room in a house. A VPS is an apartment. Dedicated is the house.
Start With the Shape of Your Traffic, Not the Volume
Monthly visitor counts mislead people. Ten thousand visits spread evenly across a month is a light load that shared hosting handles without noticing, because at any given second only one or two requests are in flight. Ten thousand visits that arrive in the forty minutes after a newsletter goes out is a different site entirely, and it is the burst, never the monthly total, that decides which tier you need.
Shared hosting enforces limits per account: a ceiling on concurrent PHP processes, on CPU time, on memory per request. Those ceilings exist so that one account cannot starve the others, and they are the reason shared hosting costs what it does. When your burst crosses them, requests queue, then time out, and visitors get a slow page or an error page instead of your site. The signs your website has outgrown shared hosting are mostly variations on this one mechanism.
So the first question is how many visitors arrive at once, at the worst moment, rather than how many arrive in a month. A blog with a steady readership stays on shared hosting indefinitely. A store that runs flash sales, a site that gets linked from a large newsletter, or a booking system that opens registration at nine on a set morning needs resources that are reserved for it, which means semi-dedicated at the least and often a VPS, even when its monthly totals are small.
If Your Software Needs More Than PHP and MySQL
The second question is what the site runs. Shared hosting is built around a fixed stack: a web server, PHP, MySQL or MariaDB, mail, and cron. WordPress, Joomla, Drupal, an online store on a PHP platform, a forum, a course site: all of it fits, and the one-click installer on a shared plan exists precisely because these applications have identical needs.
The moment you need something outside that stack, shared hosting stops being an option regardless of traffic. A Node.js or Python application that has to run as a persistent process. A Redis instance you control. A specific PHP extension the host does not compile in, or a memory_limit beyond what the plan allows. A cron job that has to run every minute. A kernel module. Any one of those is a VPS requirement on its own, and no amount of traffic headroom on a shared plan changes that.
It cuts the other way too, and this is the first opinion in this post: do not buy a VPS for a WordPress site because a forum told you it is faster. Left unmanaged, a VPS is slower than a well-run shared server until you have tuned PHP-FPM, configured a page cache, and set up the monitoring that tells you when something breaks overnight. If the only reason is speed, fix the site first. A VPS bought for root access you will not use is a server you now have to patch.
Who Is Going to Run the Server
Root access is the feature people want and the responsibility people forget. On shared hosting, the host owns every layer below your files. On a VPS or a dedicated server, the operating system is yours: security updates, the firewall, the web server configuration, the database tuning, the backups, and the reboot when a kernel update needs one.
Be honest about this before anything else. If nobody on your side can read the output of top and free -m and know what to do about it, an unmanaged VPS is not a step up from shared hosting. It is a step sideways into a job. The managed or self-managed VPS decision exists for exactly this reason, and it is worth settling before you compare a single plan.
Dedicated servers raise the stakes again. The hardware is real, so a failed disk is your outage to work through, and the capacity is large enough that a misconfiguration can waste a great deal of it for months before anyone notices.
The Tier Most Comparisons Skip
Between shared and VPS there is a fourth option, and it is the right answer for more sites than the three-way framing suggests. Semi-dedicated hosting keeps the shared model, with the host running the operating system and the control panel doing the administration, but places far fewer accounts on each server, so the per-account ceilings are much higher and a burst has room to land.
For a site that has hit shared limits but does not need root, that is usually the correct move. You get the headroom without the work. BestPaidHosting sells semi-dedicated plans on the same Hepsia control panel as its shared plans, so moving up changes how much of the server an account may use and nothing about how it is managed.
Second opinion: most people who believe they need a VPS need this instead. The ones who genuinely need a VPS already know it, because they can name the process or the package that shared hosting refuses to run.
What Each Tier Costs, and What the Price Buys
The prices below are read from the live plan data and update when it changes.
| Tier | From | What the money buys | Who runs the OS |
|---|---|---|---|
| Shared | $3.95 per month | An account on a shared server, with a control panel | The host |
| Semi-dedicated | $19.95 per month | The same, with far fewer accounts per server | The host |
| VPS | $15.95 per month | Your own operating system, root access, reserved cores and memory | You |
| Dedicated | $79.95 per month | The entire machine | You |
Read the right-hand column first. The step from semi-dedicated to VPS buys a different kind of thing rather than more of the same thing, and it arrives with a workload attached. And the step from VPS to dedicated buys hardware you may not be able to use: a VPS whose reserved cores never rise above a fraction of their capacity will not run any faster on a whole machine, because the bottleneck was never the tier.
A Decision in Four Questions
Work down this list and stop at the first yes.
- Does the site need software outside a standard PHP, MySQL and mail stack, or root access for any reason? A VPS at minimum. Whether OpenVZ or KVM depends on whether that software needs its own kernel.
- Would the VPS you are considering leave most of its cores idle even during a burst, while you are already at the top of the VPS range? Only then look at dedicated. Otherwise buy the larger VPS.
- Has the site hit shared limits, or does its traffic arrive in bursts, while it still runs a standard stack and nobody on your side wants to administer a server? Semi-dedicated.
- None of the above? Shared, and stay there until one of the answers above changes.
Every site starts at question four. Most stay there. The expensive mistake is choosing a VPS at question four because the price gap looked small, then discovering that the gap in effort was not.
Summary
| If your site is... | Choose | Because |
|---|---|---|
| One or a few sites, steady traffic, standard stack | Shared | The limits sit far above what you use |
| Standard stack, but bursty or already hitting limits | Semi-dedicated | Headroom without a server to run |
| Custom software, persistent processes, root needed | VPS | The smallest tier that can run it |
| A VPS at the top of the range, still short of resources | Dedicated | The next unit of capacity is a whole machine |
Start from the four questions, not from the price table. Then open the right plan page. The shared hosting plans and the VPS plans each publish their current allocations, so the comparison the questions point you toward is one you can make against real numbers.
If the list ended at dedicated, the dedicated server page carries the hardware options and the add-ons, and it is the one page here where reading every line before ordering pays for itself, because the capacity you are about to reserve is a whole machine and the decision is harder to walk back.
