Virtual Private Server
A VPS is just like a dedicated server, it offers to its users like root SSH access, administrative control, flexibility to install custom software and applications etc but at an affordable price compared to a dedicated server. As a user you can get your own virtual environment with dedicated amount of server resources for your own usage.
VPS Hosting is an isolated environment whereas in a shared hosting environment the server resources are shared among all accounts on the server. In a shared environment you have limitations that are determined by the host whereas with VPS Hosting you are in control – you decide how and what your server is to run.
Virtual private servers bridge the gap between shared web hosting services and dedicated hosting services, giving independence from other customers of the VPS service in software terms but at less cost than a physical dedicated server. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS. Certain software does not run well in a virtualized environment, such as virtualizers themselves; some VPS providers place further restrictions, but they are generally lax compared to those in shared hosting environments. Due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
When to go for VPS Hosting: When you website is growing bigger day by day or when your website consume more resources in shared web hosting. In shared hosting, your websites are shared with many other websites, When your website consumes more resources, then It will affect the whole server and also all the websites hosted in the same server. In this situation web hosting company is forced to move you to VPS or dedicated server to provide quality service to other customers.
Once your website becomes large enough for you to consider paying for the technology of a dedicated server, you will know that you are finally among the other "big boys" of the Internet.
While some providers of dedicated server hosting offer to fully manage your server (at an additional cost of course), you can choose to save some money by handling the technical stuff on your own.
However, if you are not skilled enough as an administrator, you run the risk of facing complicated situations. On the up side, you are in complete control of every part of your site.
Remember, do not select from among cheap hosting providers if your site requires a great deal of bandwidth as well as disk space, even if you feel confident that your website will grow in the future. Make the right choice in the beginning and prevent problems in the future.
A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc. Server administration can usually be provided by the hosting company as an add-on service. In some cases a dedicated server can offer less overhead and a larger return on investment. Dedicated servers are most often housed in data centers, similar to collocation facilities, providing redundant power sources and HVAC systems. In contrast to collocation, the server hardware is owned by the provider and in some cases they will provide support for your operating system or application.
