Why do you need a VPS?
Many bought VPS, thinking it is a server. But until……. Yes, someone is telling you are still sharing a server. Huh? am I? Yes, in the web hosting market a server may cost you a few hundreds a month, a VPS may cost you as little as $10, it will make no sense if some hoster is selling a server at $10. It is never possible.
So, what is a VPS? VPS shares a server and the server is partitioned into a few VPS. Sharing resources like CPU, Memory and even operating system. Alright, it is sharing, isn’t the same as shared hosting?
Not exactly, even they are sharing a server but overheads on VPS is still higher. VPS has its own operating system, control panel and a dedicated IP. Don’t get me wrong, shared hosting user gets or an option for dedicated IP but control panel is shared for sure.
So VPS is better? It may not the case if the hoster uses an operating system like ClloudLinux they can limit the usage of resources of one user sometimes not advertised. As such, User can decide to choose a VPS with greater resources for better performance. But if the hoster is not doing this, and the server is not overpopulated, shared hosting can be a better performance than a VPS. A shared user can consume what is available since there is no limitation.
Thus CloudLinux is a popular choice to hosting providers sell Shared Hosting because it will throttle your usage as soon as you hit the limit.
Another reason is dedicated IP is available out of the box for VPS, there is no additional cost. So, you are sharing the same IP address with others especially good for outgoing email because of RBL.
Resell web hosting space is also the reason of buy VPS, instead of a few shared hosting accounts, you can administrate your own customers, their control panel accounts, FTP accounts etc.
Most VPS has the greater room of expansion. You can upgrade the resources like RAM, CPU or disk place and some even let you choose between SSD or the conventional hard drive.
I personally like VPS for its flexibility. I move an instance often, thus portability is important. Currently, our VPS offers this and it is easy to back things up or roll back especially they are your Sandbox. Basically, I use them for my own reason. How about you?
