VPS is mid way between dedicated and shared server due to it’s better functionality and features at present time. VPS stands for virtual private server. This servers are created by server software, which divides the server’s hard drive into different partitions and installing a separate operating system on each of them. Each partition works individually and result is multiple virtual machines. Each VPS have their own, completely independent hosting parameters and individual operating any user wants to buy vps server the choice of configuration is big issue and it’s totally depend on requirement of user and service of vendors.Those are some factors which makes there VPS best.
Server type: Basically 2 type of virtual servers- managed and unmanaged are most popular in user go with managed server then it’s not a critical issue to choose server configuration, but if he wants to choose unmanaged vps then configuration plays an important role because in case of unmanaged vps, total control of server is in hands of user so it’s important to give attention on hardisk space, O/S and control panel for making VPS best and easy to use.
Operating Systems:At present scenario Linux is most popular operating system due to its free of cost easy availability so most of vendors suggest CentOS, debian and Ubantu as operating system for vps server. But as configuration point of view CentOS 5.x 32-bit is best for user. Some vendors also offers windows, FreeBSD (UNIX) but as cost point of view windows is more costly if user have limited budget then Linux is always an better option.
virtualization Type:Now days there are two most popular virtualization technologies – Xen and OpenVZ. Both provides Root access, Easy setup of network etc. Mostly VPS vendors recommend OpenVZ if you are new to Linux, as Xen is more configurable, and may require more Linux administration skill.
Control Panels:A control panel is very important for site management so it is very important for users to choose control panel carefully. Leading VPS control panels are DirectAdmin and cPanel. cPanel is VPS friendly due to its site and data backup, email, spam and virus filtering and more of features so mostly vps service provider offers cPanel.Another frequently offered control panel by VPS vendors is Webmin, free open source server/account management software.
Amount of RAM and Disk Space:RAM and Disk space is basic part of any system so those parameters are usually depends according to the server specifications. A linux vps account with 512 MB memory and 20 GB of drive space will do nicely and It’s possible to run with less than that, even as low as 256 MB memory, but you’ll have to give up email virus scanning and including control panel, so thats why 512 MB account is recommended.
Installation of Software:There are many software required, if user chose unmanaged linux virtual private server plan but don’t worry there are free setups available on the following list of software generally required for setting – generally installed software-bind is known as LAMP – Linux + Apache + PHP + MySQL. This configuration works well with any kind of sites and is recommended for is the most recommended software set for cPanel-based servers, as cPanel allows to manage all services via web-interface.
Basically according to most of VPS administrator above mention factors are most important for any User to make best VPS.
