Works fine for static sites. Works fine for anything PHP. PHP versions are kept up to date.
But the cost of an additional site is effectively cost-free, so I'm hosting several small sites for small organizations and individuals.
It has always been very peculiar. You either had very stripped off permissions of what you could do: FTP comes to mind first, and then you still need to understand how Unix permissions work, and then you wish you had SSH; or you get SSH with some stripped off permissions, and then you do need to have the skills to use the Unix system inside; or you find that the underlying PHP/webserver has 6-month-old zero days and someone keeps owning all tenants all the time, but the sysadmins are prima donnas on power trip who know better.
And you are still in a firmly DIY area most of the time, with enough footgun to do you harm.
Oh, and if you want a custom domain, welcome to the special hell.
Maybe I had bad experiences 15 years ago, but in my opinion, they should be called "mismanaged services".
Not sure what you mean by stripped off permissions. Yes, I'm not root, but most VPS providers don't give me root access either (at least not for cheap).
SFTP has always worked, and continues to do so.
Of course you need to understand UNIX permissions. You also need to understand what a directory is, what a file is, etc. It's not asking too much.
I've tried 3 different providers, and they all had SSH access. I've not heard of one that doesn't.
The only problems I had with PHP servers is that the admins are doing their job and removing old vulnerable versions. Which is a pain for me but it's why I pay them. The whole point of shared hosting is they're taking care of the zero day exploits for me.
Custom domains? Not sure what you mean. Every provider I looked at it made it painless to use.
Having a simple LAMP stack is dead simple to use (yes, as long as you know basic UNIX). VPS: I suddenly need to set up the web server, and manage DOS attacks, etc? And keep track of all the security vulnerabilities and keep upgrading? I don't want to deal with that pain. With shared hosting, I need to "fix" things less than once a year. My web apps happily work without my needing to log in.
With a VPS, I have to pay more only so that I have to do more work? No thanks.
The only non technical people using shared hosting now are people who paid to have a site built for their small business twenty years ago and don't need to update anything, so they just keep paying the bills
The whole industry has been on life support for a long time. just look at all the brands Endurance has bought up. That hasn't happened because all of those hosts were making a ton of money
How do the remaining people create a blog?
