Starting reseller business five years ago or earlier the business owner had only two options: signup for a shared hosting account with reselling feature or order a dedicated server. The initial option was a fine solution for starters since it was cheap, but as soon as the resellers’ business developed they needed a step-up. The problem however was that a dedicated server was still not affordable for them, while the resource usage of both resellers’ and their resold accounts became completely unbearable for a standard shared servers. This led to continuous suspensions of accounts and constant quarrels, some of which were even brought to social media. Finally, either the hosting company met halfway with the reseller offering some discount on upgrade or the reseller quit the company to signup for another shared hosting plan with another host. A lot has changed since VPS hosting has been introduced, so nowadays hosting reselling is not that tough, expensive and risky business.
What is a VPS and How It Works?
A VPS is a Virtual Private Server – an isolated virtualized environment with its own OS (Operating System) and emulated hardware, hosted on a physical server a.k.a. carrier. Those virtual servers are setup within a carrier by means of virtualization technology, which allows to run several isolated boxes, letting them operate independently from each other and provide the performance rates, similar to the ones of a dedicated server. Though there are several virtualization technologies, the common idea implied in all of them is to create conditions, on which several operating systems could function within single hardware set – one physical machine. There are many backgrounds for such an idea – energy use reduction, hardware use optimization, setup and maintenance cost cutting, etc. The main thing is that this idea works well for many business solutions including hosting reselling – let’s take a closer look, at which aspects specifically.

Scripts Resource Intensity
Nowadays having a personal website is as common as having a cell phone. Some people use cell phones for just giving and receiving calls and messages and some cannot simply imagine their mobile telephony device without a camera, an MP3-player and so on. It really is likewise about the websites: some website owners use their hosting accounts to bring up pages on the web and use email at their own domain. The others want their websites to be an ultimate public project, which would support many options starting from integration with social networks and ending with, but not limited to provision of downloadable content.
The way the sites are built is a question of demand, of course. But this question raises another one in turn – a question of approach. Many website owners start with shared hosting but then face with the problem of resource overuse, as their projects keep developing. And that’s where the question of approach becomes essential – those who take such issues seriously usually decide to upgrade in order to avoid temporary suspension due to excessive resource usage.
Of course, the website owner may not always realize the influence of his/her particular account on the entire server. On the other hand, server administrators are always glad to assist with the resolution of the problem. Those suspensions are mostly a preventive measure, which doesn’t let the entire server go down. For example, our team is always open for a dialogue and we co-operate with our Customers to find out the way to get the issue resolved. However, if it is definitely not about some particular script or module which is enough to be disabled to let the account keep working on the shared server – an upgrade is the next step.
VPS as a Hosting Ground for Resource Intensive Websites
Several years earlier the word “upgrade” would definitely mean a setup of a dedicated server, which would be tens times more expensive, than a shared hosting plan you used to have. Modern technology, however, has introduced a more liberal solution – Virtual Private Server (VPS). Those virtual servers are containers, created by means of virtualization software on physical servers. Current platforms allow a VPS web hosting user to obtain almost the same level of performance as the server-carrier provides, which means that a user can get a dedicated server, though a virtualized one, for a significantly cheaper price.
Using web hosting services normally presumes storing content located on a remote server that is available online 24x7x365, which means that such a hosting server is powered and connected to the Internet constantly. A very important notion in web hosting technology is uptime. Wikipedia defines it in the following way: “Hosting uptime refers to the percentage of time the host is accessible via the internet“, therefore, if a customer is paying for hosting services, it is crucial for him to expect and receive the maximum uptime values. Although hosting companies do apply various monitoring techniques to track server’s state at any given moment of time, no technology is perfect and thus it is important to perform your own independent uptime monitoring, which may come in handy in emergency situations. So how do you measure uptime values correctly? Should you expect a 100% uptime? What web site monitoring tools are available to a regular user? These questions are not as simple as they appear at a first glance. Information in this article will be useful to those interested in understanding and monitoring uptime of an account or server.

Virtualization is a widely used technology nowadays. A whole set of hosting plans is based on it – the so-called Virtual Private Servers (VPS). They allow steady transition from regular shared to the most powerful dedicated solutions. While big projects may require the power of an independent dedicated server, some personal and small-to-medium businesses may not need such resources at high costs at first. At the same time the needs of such customers may not be satisfied with what regular shared hosting has to offer due its nature . Unlike shared hosting, V PS allows full isolation from other users on the host server. It provides full control over the account (i.e. root access), remote reboots and system restore.
Nowadays various approaches and implementations of virtualization exist. In this article we will compare two most widely used virtualization engines: OpenVZ and Xen. The main goal of the article is to provide basic concept, and outline the differences and similarities of the two engines.
