A virtual private server VPS is a virtual machine sold as a service by an Internet hosting service. The virtual dedicated server VDS also has a similar meaning. A virtual private server runs its own copy of an operating system OS , and customers may have superuser -level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes it is functionally equivalent to a dedicated physical server and, being software-defined, can much more easily be created and configured. A virtual server costs much less than an equivalent physical server. However, as virtual servers share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines. The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance. Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in

A web hosting service often shortened to web host is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation , also known as housing in Latin America or France. Until , the Internet was restricted to use only " The World Wide Web protocols had only just been written   and not until the end of would there be a graphical web browser for Mac or Windows computers. To host a website on the internet , an individual or company would need their own computer or server.
Announcing a New Approach to Private Cloud
Fedora Cloud images are designed to be run and managed as scale-out undifferentiated "cattle", while Fedora Server is intended for more "pet-like" individually-managed servers. See this presentation if you aren't familiar with the pets-vs-cattle cloud computing metaphor. This helps address some of the blurry lines between the Cloud and Server products. It gives an easy path for someone who wants to run a traditional server in a public or private cloud environment to get there from images we provide. And, if someone's intended-to-be-cattle server starts developing a personality, this gives a way to deal with that. Will work with Cloud and Server SIG members to develop the script and documentation and policies around it. Systems migrated to Fedora Server in this way should be upgradeable via the normal processes recommended for Fedora Server upgrades, subject to the inherent limitations of cloud providers e. Adopt Your Cattle! Fedora Cloud is aimed at providing scale-out, largely undifferentiated compute resources.
