Users frequently confuse virtualization with cloud computing. Although both technologies create valuable environments, they have distinct differences. In essence, virtualization involves creating simulated versions of a machine’s software or hardware components, whereas cloud computing is a model that allows users to conveniently access a shared pool of resources.
In this blog, we will delve into the differences between virtualization and cloud computing and examine their implications for applications.
Virtualization vs. Cloud Computing
What is virtualization?
Virtualization is the process of creating multiple simulated environments on a single physical hardware system. One of the most common types of virtualization is server virtualization, which involves running several virtual server instances on a single physical server. This technology can also be applied to other resources, such as applications and desktops.
In the virtualization process, hypervisor software operates on top of the physical hardware, managing and distributing the machine resources to the virtual machines. For instance, when you virtualize a Windows application, the application is encapsulated in a virtual framework that resides on the end-user device, keeping it distinct from the operating system.
What is cloud computing?
Clouds represent complete IT environments that abstract, combine, and share resources over a network. Cloud computing refers to the process of running workloads within these clouds. While cloud computing is an action, clouds serve as the environments where applications operate.
Cloud infrastructure is typically located off-premises and may involve virtualization or container software that allows for resource pooling and sharing. Common types of cloud computing include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Desktop as a Service (DaaS). Generally, there is an operating system at the foundation of cloud computing.
Should You Move from On-premises Virtualization to Cloud Computing?
Many business leaders are turning to virtualization in their on-premises datacenters to reduce infrastructure costs and take the initial step toward cloud computing. This shift can kickstart digital transformation, allowing organizations to operate more efficiently. However, transitioning to the cloud allows for the implementation of enterprise-grade applications without the need for significant infrastructure investment.
Organizations with a virtual infrastructure can take advantage of the cloud to consolidate virtual resources and streamline management. Additionally, creating a self-service portal for users can enhance accessibility. A recommended approach is to migrate your infrastructure first, which can facilitate a smoother cloud migration process.
While virtualization has its benefits, the cloud presents distinct advantages. It is more dynamic than traditional on-premises virtualization and supports the creation of hybrid environments.
Adopting a hybrid multi-cloud strategy involves integrating public clouds (like Google Cloud or Microsoft Azure) with a private cloud and the on-premises infrastructure owned by the enterprise. Instead of juggling multiple dashboards for each cloud and another for on-premises virtualization, hybrid-cloud solutions enable organizations to manage everything from a single interface.
Transitioning to a hybrid-cloud deployment necessitates a shift in perspective, moving from a focus on servers to a focus on services.

How to Go from Virtualization to Hybrid Cloud
1. Focus on skills that support hybrid-cloud deployments
Focus on skills that enhance hybrid cloud deployments. Shift your virtualization strategies to prioritize the capabilities, resources, and infrastructure necessary for supporting hybrid-cloud environments. Start by aligning your cloud objectives with your business goals and setting clear targets.
Additionally, consider what portion of your workloads will remain in the private cloud and how you will handle shared, virtualized, and scalable resources. Review the requirements and make adjustments as needed. Identify which of your existing workloads are appropriate for a hybrid cloud setup.
2. Design cloud services to minimize shadow IT
Hybrid clouds offer users convenient access to resources, but deploying both unmanaged and managed devices can be challenging. A hybrid cloud setup necessitates self-service cloud access while maintaining IT governance and security. With a service-centered approach, the emphasis is on how IT services are delivered and utilized. This ensures that your resources stay secure and the employee experience remains unaffected.
3. Optimize IT in the cloud
After the workload is deployed, what steps are taken to guarantee security and compliance? A cloud environment that utilizes virtualized resources offers greater dynamism compared to a traditional static virtualized data center.
To avoid potential problems, it’s essential to implement automated provisioning for on-demand service access and revise any service management processes accordingly. Additionally, it’s important to enforce automated compliance policies to maintain security across the hybrid environment.
What to Look for in a Virtualization Provider
1. Does the provider’s solution have a proven track record and is it well respected in the industry?
You should conduct thorough research to ensure that the provider’s virtualization solution has positive reviews and has been established long enough to build a strong reputation.
2. Is there a public update release timeline and a continual vision for improvement and innovation?
Understand how updates are rolled out, their frequency, and how customer feedback is incorporated. Consider how the provider’s solution will keep your company at the forefront of technology over the long term.
3. Does the provider have extensive ecosystem documentation and support?
The provider ought to offer a comprehensive set of documentation for the virtualization solution that is easy to search and regularly updated. Additionally, they should have a support team available to assist with any issues you may encounter.
4. Is the virtualization solution flexible and does it play well with others?
As your enterprise grows, you need the ability to adapt your systems and processes, which may require integrating new software and technologies. The virtualization solution you choose should work seamlessly with the technologies you currently use or may adopt in the future, and it should be scalable to accommodate future workforce expansion.
Conclusion
In conclusion, while both virtualization and cloud computing are related to efficient resource management, they serve different purposes. Virtualization creates virtual versions of physical resources, making it easier to manage hardware. Cloud computing, on the other hand, delivers resources and services over the internet, offering scalability and flexibility. Understanding these differences can help businesses choose the right approach based on their needs for performance, cost, and accessibility.
