It's a very... raw post.

Shared hosting: performance can be affected by other sites

False. If the provider uses Cloudlinux and doesn't oversell like crazy, there's zero performance impact by other sites.

You also forgot to add:

- Shared hosting: More features, everything will cost you extra on a VPS: Softaculous, cPanel, Litespeed, Backups.

VPS: Dedicated resources - your own CPU, RAM, and storage

False. VPS is just a shared dedicated server. CPU and Network is shared unless clearly mentioned otherwise. But those services usually have a different name, VDS (virtual dedicated server)

VPS: More reliable performance - other sites can't slow you down

Partially False, because if someone uses lots of CPU, you'll feel it. If someone gets DDoSed, you'll feel it. If someone uses lots of network and IO, you'll feel it.

You also forgot to add the huge overhead of management between them. On shared hosting, the provider is responsible for security audits, updates, maintenance (of the server/hosting environment). On a VPS (unless it's managed) that's 100% on you, and let's be honest here, people are lazy to update their wordpress with 2 clicks, I can't imagine how many people log into SSH and update hundreds of packages, configure their firewall, secure their ssh, etc.

Also, a little dirty trick, if you're on a VPS and you get attacked, they will cut your IP (nullroute) and not really waste any time trying to actually filter the attack (because it's cheaper, faster). If you're on a shared hosting (and shared ip) they will absolutely try their best to mitigate and filter the attack, because it's not just you who's going down, it's potentially hundreds of customers (which means hundreds of support requests)

I expected more from someone being in the business from 1997, or are you stuck in 1997ish concepts?

Personally, I would add that the VPS server must be maintained (updates, backups, bug fixes, security management, etc.). Maintenance can be done by the host (for a fee) or directly by the person renting the VPS (if they are capable).

There's also hybrid hosting like SpinupWP where the server updates are managed but the server itself is a VPS you own and control.

VPS =/ VDS

VPS Still share cpu usage, meanwhile VDS is 100% cpu usage for your own.

Look at Hetzner CCX13 plans for example. They are VDS not VPS.

This is the first thing that stuck out at me too

In theory VDS is dedicated, but you have no way of actually knowing this unless you benchmark it daily.

I've had an extremely good experience with Hetzner, there is basically no performance difference between their shared and dedicated instances, I was able to get top performance from both!

Interesting. I had no idea these were both options.. Very cool. Thanks!

No problem! Unfortunately, they get lumped together more often than they should.
