An Overview of our KVM Linux Virtual Server

kvmbanner-logo2_srhvnwOur Linux Virtual Server is a reliable, scalable, and very available load balanced software constructed on top of a cluster of real servers. Linux’s operating system runs the load balancer to keep everything running with optimal speed and efficiency. Virtualization is always an ideal option in its ability to increase server utilization and decrease energy costs. The server cluster’s workings are completely visible to the users, who have the ability to interact with it. LVS allows load balancing of web and mail servers as well as other networked services. Potential uses include VOIP, web, email, and media services, managing workloads, organizing storage, reducing costs – the options are as limitless as your creativity!

The virtual server takes away the inconvenience of having to use up your own storage, while still providing the benefit of complete access for the users, who can interact with it just as if they were personally hosting the server.

The benefits of using KVM (kernel-based virtual machine) virtualization include the ability to run numerous virtual machines of Linux or Windows. Each virtual machine is complete in itself with its own private hardware. KVM’s loadable kernel module supports the core virtualization infrastructure and a processor specific module. KVM has rapidly become the default open-source system on Linux for creation and the support of virtual machines.

All of our LVS versions come with KVM virtualization, in addition to many other helpful services such as hardware-based virtualization, high performance SSD, nightly backups, unlimited bandwidth and network transfer, and more

The Linux Virtual Server’s endless flexibility and on-going growth make it a useful and exciting server to work with.
