WorldLink Communications Ltd has introduced a Virtual Private Server (VPS) to its enterprise clients. A VPS is a server created using software virtualization. It functions like a physical server, but it is a virtualized instance created within a server. A single physical machine can host multiple virtual private servers. A cloud-based VPS may be hosted across multiple servers. 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.
