VPS , or otherwise VDS is a set of specific hosting services when the user rents a virtual server. Virtual Private Server (machine) operates as a real physical server with the possibility for the end user to install different software, install the site using remote access to the server and more. On a single physical machine can run multiple independent users not connected to each other.
The work of a virtual server is similar to the work of a physical machine. You can place an unlimited number of sites, install applications, some databases, and so on. Your virtual server has a unique IP-address, and you are its sole owner. You may obtain additional IP-addresses in your personal account.
Important note: your VPS server is fully independent from other servers located on the same physical hosting machine, that is, your server will work great even if someone of your hosting "neighbors" cease to function. Also, when compared to conventional hosting, virtual hosting on a dedicated server allows you to enable protection against DDoS attacks. You can activate this service in your private control panel.
Today, many people own and operate their own web sites. As a rule, people are buying hosting from a vendor, get a basic control panel and can upload their site to the FTP for universal access. It`s just up and running, but there are serious limitations. If you are a serious web developer, shared web host is not exactly the best solution, because the real control on your part will be limited. You are able to create FTP accounts, e-mail addresses, and other relative things, but you can not control the software configuration. Because most web servers placed various web sites on a single machine, software packages are rarely updated.
What can you do if you have PHP 5.2.14 installed, and you need version 5.3.3? In shared hosting you will fail in this task. But on the VPS, having full control over the operating system, you can set what you want. VPS does not require a high level of professionalism in a setup. VPS solution is reliable and easy solution to participate in online everyday life.
