Drawbacks of Virtualization
Virtualization can potentially have security issues as well. All associated virtual machines and operating systems are at risk if the hypervisor is attacked. Because virtual machines may connect with one another without a real network due to hypervisors, it might be challenging to spot suspicious activities.
Virtualization Fundamentals in CCNA
Virtualization is the process of operating a virtual computer. Software used in virtualization enables you to run virtual systems, hardware, and applications on a single machine. Most frequently, it is utilized to run various operating systems, including Windows and Linux, on a single device. To make the most of the hardware, virtualization allows you to divide up huge systems into numerous smaller ones. Think of servers, for instance. The usage of virtualization enables you to divide a single server for several purposes rather than using many servers to perform distinct activities. As a result, one of the servers can be divided to manage both mail and apps rather than having servers for networking, email, and apps that aren’t being used to their full potential. The effectiveness of the server is maximized by doing this. By utilizing the hardware of the server, such as the processor, RAM, and storage memory, virtualization can turn a single physical server into a number of virtual PCs (virtual machines) that serve as digital computers. Each virtual machine operates independently, just like an actual computer would. Therefore, virtualization is the ideal way to utilize a single machine.
Large data centers that provide website hosting to the public use cloud computing. The foundation of cloud computing is the complete virtualization of servers. The large data center uses a single, high-end server to host a number of websites that may be accessed from any public IP address and require different forms of authentication. The user only paid for the services that he actually needed. If a website only required 10 GB of space to be hosted, the customer would only pay the service provider for 10 GB of space. He does not have to pay for the entire SAN (Storage Area Network) or NAS (Network Attached Storage) memory setup. Only computer hardware virtualization is responsible for this. Virtual machines can include computers, servers, routers, firewalls, etc. You can establish a virtual machine on a physical host machine and place smaller virtual machines inside of it according to your needs.
