The number of sites that you host on the server, the number of databases or mailboxes are not limited on a VPS, moreover, Hostens does not block any ports. VPS is a separate server that gives its owner the possibility to customize its settings. On shared hosting, you cannot choose any control panel or any software, as the provider has already configured it. As VPS provides full access (SSH) to VPS hosting, the customer is free to install, manage and control any software that is compatible with server virtualization.
Do you plan to sell products or services? If so, you'll want to invest in a web hosting service that offers Secure Sockets Layer (SSL). An SSL connection encrypts the financial information that shuttles between users' web browsers and your website, thus safeguarding the transmission of the purchasing information. Some hosting companies include a free SSL certificate when you sign up for a web hosting plan, while others charge close to $100. You can save some money by shopping around for services that offer the cheaper SSL plans.
Virtual means that the server runs in a virtualized environment, a cloud server rather than a physical server. This differentiates Virtual Private Servers from dedicated servers, which are physical machines in a data center rack. Virtual servers have the same functionality as a dedicated server and they look more or less the same from the client’s perspective, except that several virtual servers live on a single physical server.
A VPS Server is the reasonable web hosting choice for your domains when more system resources are needed. VPS takes of the virtualization technologies to partition physical servers into several virtual machines. Virtual Private Server Hosting is the future of modern hosting as it provides the power and functionality of a high-end dedicated server but at a much lower price. Main virtualization technologies used including Vmware, OpenVZ and XEN etc. By purchasing a VPS hosting package, you get a 100% individual machine with your own dedicated CPU and RAM, and mostly root access to the hosting server. Each Virtual Server can run under its own operating system (Windows server, CentOS and other Linux distributions) or have custom configurations of its own.
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
