Virtual private servers have become a popular choice for web hosting because they offer many benefits of dedicated servers at a lower cost. They also provide the added benefit of easy scalability. Since each VPS is virtualized, the configuration can be updated with a software modification rather than a hardware upgrade. Still, dedicated servers often provide better performance since all the resources of the physical machine are dedicated to a single server.
Most people are clueless about the virtual servers hosting and how they actually work on the shared environment. It is a known fact that thousand and more number of users tend to use a server at a time. In such circumstances, each user is allocated with a designated amount of disk space, bandwidth, CPU allocation, memory and Operating System, which can be used on the server. All the Virtual Private Server users share the same CPU and RAM and think that, they have dedicated set of hardware. Virtual Server software is loaded onto the physical system and from then, a virtual server is ready to be used.
But if you require a lot of computing power and maximum control VPS hosting is only second to a dedicated server. Intensive websites, web apps, online game servers, databases and other kinds of complex projects are perfect for a VPS hosting service. VPS hosting provides more control than any other service, as you can install your preferred OS and take advantage of root access.
Under normal circumstances, numerous websites can operate on each of the Virtual Private Servers, which are operated on the host machine. However, if in case, a single virtual server starts to hog a lot of resources of the host computer, then it can cause poor loading of web pages and other such service lagging issues. In this situation, a dedicated server is the only solution, offered by web hosting service, in order to deal with enormous traffic and work as per the needs.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.
