Operating a VPS provides you the advantages of dedicated hosting without the associated costs! VPS is therefore ideally suited for webmasters and power users who are experienced with dedicated hosting. VPS has a great economic advantage over dedicated servers if you are running a small number of websites and your websites are not resource intensive. If you have any problems with the Operating System in VPS, you simply reload it (or you can even install another copy of the OS, depending the system you are using).
VPS is ideal for websites with high resource needs, limited budgets, and limited internal technology resources. Even if hosting a powerful resource intensive process like E-commerce, VPS helps you build your website up and stay within your budget. VPS is a low cost and lower maintenance approach to getting the functionality of a dedicated server. Through the special software installed on the server, accounts created on VPS are completely isolated from one another.
Virtuozzo
Virtuozzo is one the common operating systems for VPS. Users requiring a VPS in the less than $50 price range typically would utilize Virtuozzo. For those webmasters looking to avoid CPU/RAM quotas with their shared hosting, and who want to run their own servers (for example, need to run cron or require open ports) or need dedicated IP’s, VPS is the ideal solution.
Cpanel
Cpanel is a common control panel for dedicated hosting and VPS. Cpanel is in wide usage because of its flexibility and easy to work with and having a lot of key features; it is one of the top operating systems for VPS as well as dedicated hosting. CPanel is a fully featured control panel. For webmasters transitioning from shared hosting, Cpanel is a way to ease this transition and allows you to begin web hosting without becoming lost in the technological details of Linux. Cpanel is also helpful when adding features such as blogs (e.g. WordPress) and message boards to sites, which can be done using built-in features of Cpanel.
VPS vs. Shared Hosting
Shared hosting is usually not suitable if there is a chance of your application overloading the servers and its resources. Shared hosting only makes sense if you are running a low-end site. Shared hosting providers typically do not let you to install custom features or run cron jobs, whereas you can do that VPS. On both shared and VPS accounts, support is provided for ready-made features. On the other hand, if you have a low end website (low traffic, low resource usage) shared hosting makes sense because these accounts are run on high performance computers, in order to be able to host a large number of websites.
In summary, if you do not have the high end needs of a dedicated server and also you do not want to by fully responsible for a web server, or you have a budget, VPS is an attractive option. When your needs grow, you can always opt for a dedicated server.
