VPS means Virtual Private Server, meaning it is a personal virtual server. The first reason we prefer VPS is that the number of visitors is high. When the hosting or reseller that we use is able to meet our needs, we need to switch to the virtual server, which is one of the top packages. Different options are offered according to your budget. In general, packages between 512 mb ram and 2 gb ram are offered.
VPS is a public virtual server that is software divided and shared on multiple sites. The amount of ram that you own is used by other sites when you're not using it, so it's not entirely dedicated to you. With a VPS the resources of the server will be split between different websites or hosting accounts.
Dedicated Server can be converted as rental or physical server. We're talking about your own physical server. Suitable for sites with very high number of individual hits. Both ram, cpu and storage are very high from VPS and VDS. Monthly fees are at least 100-200 dollars.
A dedicated server is a server that’s literally dedicated to your own personal use. You’ll have rights to all of the resources of the machine, and you’ll be able to configure the hosting environment however you wish.
If basic shared hosting doesn’t quite offer what you need and you need a little more control over your host, then VPS hosting could be the right fit for you. If you need a more advanced host with extensive customization options, then check out dedicated hosting.
