Benefits of virtualization Virtualization offers numerous benefits mainly by improving organizational hardware utilization and management. Some of these benefits include: Cost-savings: Traditionally, organizations deploy one production application in one operating system environment to ensure reliability.

Without virtualization, this approach limits one application deployment per physical machine. However, not all applications fully use the resources available on the physical machine, leading to inflated costs. Virtualization alleviates this problem by allowing you to use resources more efficiently through virtual machines, improving utilization efficiency and cutting IT infrastructure costs.

Easier Deployments: In the traditional approach, deploying a new application or creating a test environment requires procuring a new physical machine, setting it up, and testing the setup manually.

This is time-consuming and becomes chaotic when deploying at scale. You can also use a snapshot of a similar VM to create a new VM to bring down the time required to deploy an application. This also helps test updates in a beta environment and directly deploy successfully tested VMs without unnecessary back and forth. In case a deployment fails, you can quickly roll back the VM to an earlier state to recover quickly. Operational Agility: When you deploy an application on a physical machine, it becomes especially challenging to deal with machine failures.

Even redeploying the application from one machine to another consumes a lot of time. As a result, this can lead to lost revenue as the timely availability of business applications is critical.

A significant benefit of VMs is you can shift them from one host to another host almost instantaneously. Moreover, you can take VM snapshots at regular intervals and maintain the most-recent backups. This helps immensely when a host fails fatally or if you need to retire a host nearing its end of life. Limitations of virtualization While virtualization helps flexibly manage resources and improve IT operations significantly, it has some disadvantages: Each virtual machine needs to run its own operating system.

This approach consumes additional, redundant resources on a host. A more efficient approach to resource utilization would be containerization.

Some applications may not run in a virtualized environment and require deployment on a physical machine. If a hypervisor is compromised, an attacker could gain unauthorized access to all the VMs the hypervisor manages. Initial investments in virtualization technology, monitoring and management tools, and personnel can be significant.

These features may also make live migration of VMs possible, add to fault tolerance, and enhance security. Example features include direct memory access DMA remapping and extended page tables EPT , including their extensions: accessed and dirty bits, and fast switching of EPT contexts.

It enables usages such as workstation remoting, desktop-as-a-service, media streaming, and online gaming.
