The virtual private servers are insulated containers or virtual machines on a single server. The client’s ability is a key element of the VPS (* Virtuozzo / OpenVZ), because only one model instance of the software is installed on the physical machine. Then, through an abstraction layer that allows multiple “independent” virtual machines in this unique model are provided. This is important because it reduces deployment costs for suppliers and multiple VPS can be deployed in a server. This is the reason behind VPS is cheaper than dedicated servers.
There are three main factors, which are used by hosting providers on their VPS plans.
RAM – Random Access Memory (RAM) is a very important factor that affects the performance of virtual server significantly. It is recommended that you choose a plan that provides enough RAM for your application.
Storage – This is the amount of space you get with the SPV. This includes space for the operating system, software as a Web server, application code, content, etc.
Data Transfer – The amount of data they must be transferred to and from your VPS. Some providers have different thresholds for incoming and outgoing transmission. Data transfer is often referred to as bandwidth, although this term is not quite correct.
