The Need for Virtualization: When and Why Virtualization Took Over Physical Servers

Abstract

In early days, industries used physical role-based servers but as they were hard to scale according to the load they are getting and it was hard to manage the infrastructure; if any server is failed, then the service that corresponds to that server also gets down and a plausible solution to all these problems was solved by virtualization. Different researchers have been contributing and showing their effort to make this worth in the past. In this work, the server has been deployed and Datadog tool has been used to record different parameters to check the performance. Different parameters which have been considered are CPU utilization, disk usage, disk latency, memory breakdown. The aim of this work is to show how servers are reacting when the servers are at full load and when the load is lesser. Further, the virtualized environment also provides advanced features like load management on servers in real time and it also enables the organization to make their environment more efficient and robust with more efficient backups and security.
