Such words as "virtualization", "cloud", "virtual environment" ets. have become very popular over the last several years. Virtualization is a really great solution. You may find it important to learn more about what server virtualization can do for you. There are numerous advantages of virtualization and each can give you particular benefits:
- Two, three, four or more virtual servers on one physical server. The ability to create multiple virtual servers (VPS - Virtual Private Server) on one physical server (node) which allows to substitute one physical server with multiple virtual servers, each with its own full-fledged operating system. Virtual servers are running as one dedicated server, each VPS can be rebooted separately from the others and has root access, users with their own IP addresses, memory, processes, files, applications, system libraries and configuration files. The interface of each of these servers, as well as the features it possesses, are similar to the interface and features of a separate server.
- Efficient utilization of resources in order to meet diverse challenges. Based on a common hardware, virtual servers can more efficiently utilize the resources of a physical server. It's not money-wise to buy or rent a physical server to use only 5-10% of its resources. You need to make maximal use of it without any extra costs. Virtualization is the right way to do it.
