Virtual Private Server abbreviated VPS is not a toy but shared hosting service definitely is!!! Several hold the opinion that the dedicated server is a big piece of metal which is very difficult to manage while the shared hosting is a tinker toy which is easy to handle. In this comparative study, the VPS server lies midway in the spectrum. About 90% off the worlds’ websites would be smoothly filled in the beginner’s VPS plan if one could tweak it well and maximize everything that professional server administrator could think of as well. Today VPS is powerful and at the same time costlier as compared to shared hosting.
With people getting more interested to buy VPS hosting, some tips and thoughts from experienced users are:
1. Never to go for VPS provider that provides only 192 MB of memory or RAM when thinking to buy VPS hosting. The reason for this being that the system overhead utilizing as much as 150 MB of it due to which user is hardly left with any free memory for his own applications, considering alone cPanel/WHM server administration software. Usually they are essential when considering the fact that almost all hosting clients are themselves not technical , thus requiring the software in order to manage the server skipping the part of typing commands into the console. Thus 256 MB is undesirable unless one runs an empty box that has important software like LAMP.
2. The VPS is actually not a server that is centrally managed, of which various hosting companies take immense care in terms of security. The serious fact for the user is that he himself has to worry of the security. Despite being provided with ample of tutorials as well as step by step guidance to harden and secure one’s server, the user still has to take the help of experts. Thus unless the user happens to be a seasoned server administrator or Linux security expert himself, when he thinks to buy VPS hosting he needs to opt managed VPS hosting instead of unmanaged hosting, else just not host important websites in the box.
3. When talking unit wise, virtual private servers are cheaper than the shared hosting provider, yet it still does not approach the dedicated solutions when speaking in terms of effectiveness from the cost point of view. It is because when a single physical server is divided into a number of slices i.e. Xen VPS, considerable overheads appear for each of the slices, namely individual small Linux operating systems executing in each of the individual slices where each operating system consumes about 100 MB RAM. Along with this overhead, the parent system that runs the physical server also has overhead associated with it. So overall speaking, when a single physical server is subdivided into a number of slices, a larger share of the resources is utilized by the system thereby leaving very few resources to be used by the user’s website.
