The Difference Between Virtualization And Cloud Computing

Was it confusing for you as a kid to always remember what was “left” and “right”?

Many of us might have remembered it by some skin marks, by wearing a watch or maybe something else. Well, it might not be a confusing factor anymore for us but virtualization and cloud computing can still be perplexing concepts. They both help you create useful virtual environments but they're not just about that. These technologies offer different sets of capabilities and benefits.

Virtualization caters to organizations with expansive IT infrastructures, with adoption rates consistently high. In fact, by 2024, 94% of large enterprises (with over 5,000 employees) utilize multi-cloud or hybrid-cloud infrastructure, showing the increasing reliance on these technologies for scalability and efficiency, according to Flexera's State of the Cloud report. On the other hand, cloud computing is embraced by nearly 96% of companies for at least one aspect of their IT infrastructure, and the public cloud market alone is expected to reach $675.4 billion by the end of 2024, as forecasted by Gartner. These technologies, while complementary, address distinct requirements in the modern computing landscape.

We bet these numbers have raised your curiosity about these technologies. Well, read on, as we explore both technologies in detail, how they differ and what benefits they offer. Scroll on!

Understanding Virtualization

Virtualization is like having a computer within a computer. It creates a simulated or virtual machine (the guest) that exists only in software. This virtual machine operates inside your physical computer (the host) and has its own memory, CPU, storage and operating system (OS), all defined by software rather than hardware.

These virtual machines can be customized to handle different tasks and workloads. Sometimes, they're used to emulate old hardware and other times, they help manage resources more efficiently. The best part is that applications within a virtual machine are completely separate from the host computer. So, the guest and host cannot access or interact with each other's files, ensuring complete isolation.

These capabilities make it possible to develop various applications. Let’s look at some of the examples to understand virtualization better!

Examples Of Virtualization

At its core, virtualization is about getting the most value possible from the resources you have. While virtualization can have an endless stream of use cases, here are some of the common ones.
 

• Server Virtualization

  Server virtualization allows companies to use one server and support multiple functions that might otherwise be spread across several servers. It enables users to consolidate and redistribute resources for more efficient resource utilization.

• Data Virtualization

  Data virtualization allows users to easily manipulate data using an abstraction that exists independent of actual database systems. The abstraction serves as a sort of "scratch paper" where users can check their work for errors before saving it "for real."

• Software Virtualization

  Software virtualization is designed to separate applications from the host machine's underlying hardware and OS. It helps you see how a new application will behave before integrating with your real system.

Now that we understand what virtualization is, let’s move to the next segment – cloud computing.
 

Understanding Cloud Computing

Cloud computing is a way of accessing and using computer resources over the internet, instead of having them physically located in your premises. It's like having a vast pool of computing power, storage and software elements you can tap into whenever you need it without having to own or maintain the underlying infrastructure.

Think of it as a utility service, similar to electricity or water. You don't need to build your own power plant or water treatment facility; you simply pay for what you use. With cloud computing, you don't have to invest in expensive hardware or software upfront. You can rent computing resources from a cloud provider, such as Amazon Web Services, Microsoft Azure or Google Cloud Platform and pay for what you consume.

Various businesses opt for these cloud service providers to fulfill their requirements. Let’s look at some examples of where it can be used!

Examples Of Cloud Computing

Cloud computing has a wide range of use cases across various industries and applications. Here are three examples that showcase the versatility and benefits of cloud computing:
 

• Web-based Applications

  As cloud computing provides scalability and flexibility, it helps handle user demands and storage requirements. As a result, many popular web applications like Netflix, Spotify and Dropbox are hosted in the cloud. This makes it easy for users to access these services from anywhere with an internet connection without the need for local installations or maintenance.

• Big Data And Analytics

  Cloud computing offers virtually unlimited computing power and storage capacity for big data applications. This allows organizations to leverage cloud service providers to process and analyze large datasets and gain valuable insights from them, without owning expensive on-premises hardware and infrastructure.

• Disaster Recovery

  Cloud computing offers reliable and cost-effective solutions for data backup and disaster recovery, with cloud-based businesses capable of resolving disaster recovery issues in just 2.1 hours, compared to 8 hours for non-cloud users, according to Aberdeen's study on business resilience. This allows companies to store their critical data and applications in the cloud so they can retain it in case of failures or cyber-attacks. This ensures business continuity and minimizes overall downtime.

These examples showcase what both the technologies, virtualization and cloud computing, are famous for – agility, scalability and cost-efficiency. The versatility of these technologies has made them indispensable for organizations of all sizes.

With that, let’s move on to the segment you have been waiting for – the difference between Virtualization and Cloud Computing!
 

Virtualization Vs. Cloud Computing

Virtualization and cloud computing are closely related yet distinct technologies that offer different capabilities and benefits. One key difference is that virtualization is typically deployed on-premises, meaning it's implemented within an organization's own data center or infrastructure. Cloud computing, however, is delivered off-premises, with the resources and services hosted and managed by the cloud provider.

Another distinction is that virtualization requires IT staff to manage and maintain the virtualized components, such as updating and patching virtual machines or networks. In contrast, cloud computing services are managed and maintained by the cloud provider, relieving organizations of these responsibilities.

Virtualization allows organizations to optimize their existing hardware resources and improve scalability by creating additional virtual environments as needed. However, cloud computing enables even greater scalability, as organizations can quickly and easily scale resources up or down by adjusting their service plans with the cloud provider.

While virtualization focuses on creating virtual versions of IT components within an organization's infrastructure, cloud computing delivers computing resources and services over the internet, offloading the management and maintenance responsibilities to the cloud provider. Both technologies offer benefits in terms of scalability, efficiency and cost savings but they cater to different needs and use cases.

On that note, let’s conclude this article.
