Introduction

Cloud computing and virtualization are two fundamental ideas that are essential to IT infrastructure management in today’s technologically advanced society. Even though they are often discussed together, they have diverse functions and provide unique benefits. This article explains the distinctions between virtualization and cloud computing so you can grasp their distinct functions and advantages.

What is Cloud Computing?

Cloud computing is a client-server computing architecture. In cloud computing, resources are used in centralized pattern and cloud computing is a high accessible service. Cloud computing is a payment and useful business tool, users pay for usage. 

 

What is Virtualization?

Virtualization is the establishment of cloud computing. It is this novelty that empowers a continuous asset age from certain eccentric conditions or a singular physical device framework. Here the job of hypervisor is essential, which is legitimately associated with the equipment to make a few virtual machines from it. These virtual machines working is unmistakable, independent and doesn’t meddle with one another.In the condition of disaster recovery, it relies on single peripheral device as single dedicated hardware do a great job in it. 

Virtualization exists in different classes which are:-

  

Cloud Computing vs. Virtualization: Key Differences

Let’s see the difference between Cloud computing and Virtualization:-

S.NO Cloud Computing Virtualization
1. Cloud computing is used to provide pools and automated resources that can be accessed on-demand. While It is used to make various simulated environments through a physical hardware system.
2. Cloud computing setup is tedious, complicated. While virtualization setup is simple as compared to cloud computing.
3. Cloud computing is high scalable. While virtualization is low scalable compared to cloud computing.
4. Cloud computing is Very flexible. While virtualization is less flexible than cloud computing.
5. In the condition of disaster recovery, cloud computing relies on multiple machines. While it relies on single peripheral device.
6. In cloud computing, the workload is stateless. In virtualization, the workload is stateful.
7. The total cost of cloud computing is higher than virtualization. The total cost of virtualization is lower than Cloud Computing.
8. Cloud computing requires many dedicated hardware. While single dedicated hardware can do a great job in it.
9. Cloud computing provides unlimited storage space. While storage space depends on physical server capacity in virtualization.
10. Cloud computing is of two types : Public cloud and Private cloud. Virtualization is of two types : Hardware virtualization and Application virtualization.
11. In Cloud Computing, Configuration is image based. In Virtualization, Configuration is template based.
12. In cloud computing, we utilize the entire server capacity and the entire servers are consolidated.  In Virtualization, the entire servers are on-demand.
13. In cloud computing, the pricing pay as you go model, and consumption is the metric on which billing is done. In Virtualization, the pricing is totally dependent on infrastructure costs.

Conclusion

Virtualization and cloud computing are essential elements of contemporary IT architecture. Cloud computing is perfect for organizations that want to use large resources without having to make large upfront commitments since it provides scalability, flexibility, and a pay-as-you-go strategy. However, virtualization offers autonomous virtual environments and disaster recovery options, making it an affordable means to make the most of current technology.
