Linux based servers are considered to be the most reliable and secure of all types of servers. Due to this reputation, most of the hosting is done on these servers globally. Linux servers could be shared, virtual private or dedicated. While shared hosting is done by the start-ups with little or no traffic and no requirements of customizations, the virtual private servers are used for hosting sites which receive good traffic and hit good bandwidth. The difference between shared and VPS hosting is that there are many tenants for former whereas there are few tenants for the latter. Thus, linux VPS hosting provides more server resources to tenants in terms of bandwidth or storage space. These are able to handle much larger traffic flows.
Linux VPS hosting is based on the concept of virtualization in which every tenant feels that the server is dedicated for his work only but this is not the case. Due to high levels of allocated bandwidth and storage space, there is no issue in handling more traffic on website as the traffic grows. It is just like one laptop or desktop is shared by multiple users by providing them their usernames and passwords to log into their respective spaces on same machine. This serves the need of many organization who are not yet ready to go for the exclusive dedicated servers and would want to use this intermediary arrangement for a good time to come.
Linux VPS hosting does provide the flexibility of using server resources as per ones wish. These are customizable to a good extent and can be configured to host many applications. If you have to use some specific application on the server for which separate customization might be required, VPS would give you the flexibility of doing it. However, it is better to inform the hosting service providers about your precise requirements so that the most appropriate linux sever is provided.
