Virtual Machine And Cloud Computing?


What is the difference between a virtual machine and cloud computing? A virtual machine allows you to create one or more operating systems on your computer, which are then stored on your disk drive. Cloud computing, on the other hand, is when you allow your data to be stored remotely and accessed through the internet. In this article, we explore what advantages each has over the other.

What is Virtual Machine?

A virtual machine (VM) is a software program that emulates the hardware of a physical computer. VMs are used to run multiple operating systems (OSes) and applications on a single physical machine and to isolate different OSes and applications from each other.

Cloud computing is a type of computing where resources, such as applications and data, are provided over the Internet as a service. Cloud computing can be delivered in three ways: public clouds, private clouds, and hybrid clouds.

How Do Virtual Machines Work?

A virtual machine (VM) is a software program that imitates the functionality of a physical computer. VMs are typically used to run multiple operating systems (OSes) on a single physical computer, allowing each OS to have its own virtual environment and resources.

VMs work by creating a virtualization layer between the hardware and software of a computer. This layer allows multiple OSes to share the same hardware, while still isolating each OS from the others. This isolation is important because it prevents one OS from affecting the others, or vice versa.

The most common type of VM is the hypervisor, which is a software program that manages other VMs running on the same physical computer. Hypervisors can be either bare-metal or hosted. Bare-metal hypervisors run directly on top of the physical hardware, while hosted hypervisors run on top of an existing OS.

Hypervisors use a variety of techniques to virtualize computing resources, such as CPU, memory, storage, and networking. They also provide features such as resource allocation and management, quality of service (QoS), security, and high availability.

What Is Cloud Computing?

Cloud computing is a type of computing that relies on sharing resources over the internet. This includes things like storage, servers, and applications. It’s a way to make use of scalable and elastic IT resources.

One big advantage of cloud computing is that it can help you save money on hardware and software costs. Instead of having to invest in your own infrastructure, you can access resources from a provider on an as-needed basis.

Another advantage is that it can make your business more agile. With cloud computing, you can quickly scale up or down to meet changing demands. This can be a big benefit for businesses that experience seasonal spikes in demand.

There are also some potential disadvantages to consider. One is that you may lose some control over your data if it’s stored off-site with a cloud provider. There’s also the risk of downtime if there are problems with the network or servers. And finally, security threats are always a concern when storing data online

How Does Cloud Computing Work?

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). This cloud model is composed of five essential characteristics, three service models, and four deployment models.

On-demand self-service: A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider.
Broad network access: Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing power, memory, and network bandwidth.
Rapid elasticity: Capabilities can be rapidly and elastically provisioned in response to user demand changes. Elasticity refers to scaling capacity up or down as needed. For example, Amazon Web Services allows users to increase or decrease the number of EC

The Differences Between The Two

There are a few key differences between virtual machines and cloud computing. For one, virtual machines are usually self-contained and have a specific purpose or function, while cloud computing is more of an umbrella term that can encompass many different services. Additionally, virtual machines typically run on a single server, while cloud computing can often involve multiple servers working together.

Another key difference is in the way that resources are allocated. With virtual machines, you typically have to allocate a certain amount of RAM, storage, and processing power to each machine. With cloud computing, these resources can be shared and scaled as needed, which can be more efficient.

Finally, virtual machines tend to be more expensive than cloud computing options since they require more hardware resources. Cloud computing can often be more cost-effective since you only pay for the resources you use.


The difference between a virtual machine and cloud computing is that a virtual machine is a software program that emulates a physical computer, while cloud computing is a way to access applications and data over the Internet. Virtual machines are used to run multiple operating systems on one physical computer, while cloud computing allows users to access applications and data from any device with an Internet connection.
