This morning, while brushing my teeth and shaving, a weird question crossed my mind: if Windows OS costs a lot and Linux OS is free, why do so few people use Linux. I've search the web for answers, combined it with what I already know, and here it is.
Proud to Present: Virtual Private Server (vps) The VPS was invented to enable small businesses or individuals enjoy a (dedicated) server of their own in a cost of a little more than a basic (shared) hosting and without purchasing any piece of hardware. The idea is simple: the supplier allocates a memory block and defines it as a server by installing all the software environment needed for it. Cases you don't need a VPS and can do well enough with a shared hosting: 1.In cases you have a low to medium traffic website . 2. In cases you don't have any Linux experience and prefer a simple administration panel. 3. In cases a gap of $25-$40 may be significant for you. Cases you would enjoy a VPS more than a shared hosting: 1. When you need a full server administrator access and can't do well with the very limited administrative rights given to you in a shared hosting. For example: if you need to install SSL (encryption) for your website, or if you need to modify the PHP engine configuration. 2. When you have heavy traffic coming in to your site. In case of a shared hosting, this can cause trouble (the bandwidth is more limited than in a VPS). Now, what are the differences between a VPS and a full dedicated server: 1. Though a VPS is a server, the fact that it uses the same hardware with other VPS's, limits a little the flexibility of the administrator regarding the server's configuration. 2. For the same reason, the surfing to your site can be sometimes a beat slower, because other sites using the same hardware might be flooded by traffic at that moment. 3. Using a VPS, you save a respectable sum of money due to the lack of hardware required and due to the fact that you don't have to maintain regularly the hardware. 4. Resources on demand - using a VPS, you can easily enlarge vital resources like: RAM & fixed memory. Using a dedicated server, you have to purchase an additional hardware device in such a case. Summary - a VPS is an hybrid of two: the large dedicated server and the primitive shared hosting. If you have a modest website (no video or complex graphics) with a traffic of no more than a couple of thousands a day, you should do fine with a shared hosting program. If you represent a huge portal having tens of thousands visitors a day and presenting heavy data (graphics, video), it seems that you won't escape a heavy expenditure on a dedicated server. If none of the above is relevant to you, would you consider a VPS?..
