Virtualization, although it may seem like a new trend in cloud computing, has been around for decades.
Since the 1960s, when IBM’s mainframe era started, virtualization has been a crucial part of computing’s management. It made computing easier and more efficient.
The technological advancements made since then have made virtualization possible. It can solve many common problems faced by businesses, including data center sprawl and high operating costs.
Organizations recognize the importance of virtualization skills. Some virtualization-focused certifications rank among the highest paying in IT, according to our research. Check out our 15 Top-Paying IT Certifications for more information.
These are the five most common types of virtualization:
Desktop. Multiple virtual machines can run cloud-based desktops on the same physical or virtual server.
Application. It creates a virtual instance that runs core business applications. This keeps app software separate from local operating systems.
Server. This creates a virtual machine that can replace the physical server. It allows server management via the cloud.
Storage. Data storage. This eliminates the need for physical data storage and can potentially lower the costs associated with data centers.
Network. It combines virtual and physical components to create a network that is both virtual and physical. Software switches are used to manage the network.
Desktop Virtualization
A virtual desktop infrastructure, or VDI, allows you to store and access work files in places that your team members can access from anywhere.
Desktop virtualization allows users to access multiple operating systems and applications from one computer because they are installed on virtual machines that run on a server at a data center.
Virtual machines (VMs), are basically a virtual computer that can run on a computer similar to your desk, but in software form. Hypervisors make it possible to organize and run VMs as they are intended.
Remote and local are the main options for desktop virtualization. Remote and local desktop virtualization are possible depending on the business’s requirements. Because of limitations, such as inability to access network resources via a mobile device, local desktop virtualization may not be possible. Remote desktop virtualization is becoming more popular and robust in today’s market. Remote desktop virtualization allows users to access operating systems and applications via a server located in a secure data center.
Enterprise-level businesses have a great option: virtualizing desktops. It allows employees to log in remotely in the event that there is a natural disaster or health issue that prevents them coming to work.
A virtual desktop setup can be a crucial part of a business’ disaster recovery plan or response for any unexpected events that may prevent workers from getting to work. Citrix and VMware are two of the most prominent providers in this area.
Application Virtualization
Application virtualization allows users access remote versions to applications that aren’t installed on their machine.
As demonstrated by the Covid-19 pandemic, and desktop virtualization, app virtualization is an important component of remote work.
The end-user can use the app seamlessly by virtualizing it. This allows employees to work remotely from home using the same programs that are in the office.
Virtualized apps can be run in a separate environment from the operating system, called a sandbox. The app draws its operating power from the sandbox but it will appear that any changes made to the app are being made to the operating system.
There are two types.
Remote
Streaming
Remote applications can also be run
