VPS vs shared hosting: which one do you actually need?

Shared hosting is the right answer far longer than hosting companies like to admit. Here is how to tell when it stops being the right answer.

Disclosure: I work at Bigdomainhost, an Indian hosting company, and our own products are linked below. The original version of this guide is on our site.

The actual difference

On shared hosting you rent an account on a server that hosts many customers. The host runs the operating system, the web server, PHP and MySQL; you get cPanel and a slice of the machine. It is cheap because the cost of the server is split many ways. Ours is cPanel hosting, with WordPress plans built on the same servers.

On a VPS you rent a virtual machine. With KVM it boots its own kernel and gets its own guaranteed allocation of vCPU, RAM and NVMe. You get root. What runs on it, and whether it is patched, is your decision. See our KVM VPS plans, or a VDS if you need CPU cores nobody else uses.

Four signals it is time to move

1. You need root. A specific PHP extension, a Node or Python service, a cron running every ten seconds, Redis, a non-standard port. Shared hosting says no to all of these, and there is no way around it. This is the clearest signal there is.

2. You keep hitting plan limits. cPanel's resource-usage page shows CPU, memory and entry-process limits. If you are throttled at your busiest hour routinely, not once a month, you have outgrown the plan. A single spike does not count.

3. Downtime now costs money. If an hour offline means lost orders rather than lost pride, buy the resources that make it less likely. This is a commercial decision, and it usually arrives before the technical signals do.

4. You are hosting other people's sites. On one shared account, one client's mistake can throttle everyone. Either a reseller plan (isolated cPanel accounts, still managed) or a VPS with WHM is the right move. Reseller is usually the better first step.

What is not a signal

• Traffic alone. A well-cached WordPress site serves tens of thousands of visits a month on shared hosting without complaint. What matters is uncached, dynamic work.
• "I want it to be faster." If the site is slow because of unoptimised images and no caching, a VPS will be slow too, with a bigger invoice. Fix the site first.
• Someone told you to. Upselling to VPS is how a lot of hosts make their margin. Ask what specific limit you are hitting.

Managed or unmanaged?

This is the question most people actually mean when they ask about a VPS.

An unmanaged VPS is the cheapest way to get dedicated resources. The host keeps the hardware, network and hypervisor healthy; everything above the operating system is yours: updates, firewall, backups. Right if you are comfortable in a terminal.

A managed VPS adds cPanel or Plesk, OS patching and hardening. It feels like shared hosting with the resources of a VPS. Right if your time is worth more than the licence fee, or if the box will hold client sites.

If you are unsure which you are, you want managed.

The middle option people forget

Between them sits cloud hosting: still a managed cPanel account, but on a high-availability cluster with autoscaling storage, from ₹249/mo. It answers "shared hosting is not reliable enough" without answering "I need root", which is a common place to be.

And at the other end: if you need ASP.NET or MSSQL, that is Windows hosting, and if one VPS is no longer enough, a dedicated server.

How to move without breaking anything

1. Provision the new server and copy everything across, leaving the old one running.
2. Test on a preview URL or a hosts-file entry until you are satisfied.
3. Lower your DNS TTL to 300 seconds a day ahead.
4. Switch DNS at a quiet hour.
5. Leave the old host running for a week before cancelling.
