Virtualization technology allows multiple applications to run on a single server, creating the need for virtualization management. This software helps deploy, update, monitor and maintain virtualized applications, reducing costs and improving efficiency. Virtualization management tools have evolved to include more features and strategic functions.
For years, whenever companies deployed a new application for their employees and customers, the application ran on its own server. Increasingly, companies are running many applications simultaneously on a single server using virtualization technology. This has created the need for a new type of management called virtualization management. Virtualization management helps companies deploy, update, monitor and maintain virtualized applications. Using virtualization management software, IT managers can take control of their virtualized computing environment.
The need for virtualization management has arisen due to the near universal adoption of server and application virtualization. Companies have realized that the traditional approach of a server application was an inefficient use of computing resources. Quite often, many servers have been running at a fraction of their rated performance. This proved to be very costly as each underutilized server still needed an operating system, electricity, and had to be managed. Virtualization allows multiple applications to share a single server without conflict. This allows companies to consolidate the number of servers they need to own, significantly reducing costs.
For virtualization to work, an application must be associated with an operating system in a piece of software called a virtual machine. Virtualization management software is often used to create these virtual machines. Next, the virtual machine must be placed on a server in order to run. Virtualization management software is used to install and test individual virtual machines on a server.
Virtualized applications, like traditional applications running on a server, need to be updated and tested over time. To this end, virtualization management software is used to monitor the performance of a virtual machine. If performance is below average, an administrator could use management software to allocate more memory or processing power. This would help the virtual instance of the application run faster. Similarly, if a problem occurs with an application, virtualization management software is used to identify and correct the situation. Also, the software is used whenever an application needs to have a new patch installed or an update needs to be applied.
When server and application virtualization became popular, virtualization management tools were quite rudimentary and offered only limited functionality. As virtualization has become a core part of most IT infrastructures, management tools have added many features. For example, many virtualization tools now allow IT administrators to manage their virtual and physical networks simultaneously.
Additionally, virtualization management tools are now taking on more strategic functions. Initially, the management system was used to keep applications running smoothly. Now, management tools are increasingly being used to identify usage patterns and assist in planning to meet new needs.
