As an expert in the field of technology, I've spent considerable time understanding and working with various IT infrastructures, including virtualization and cloud computing. These two concepts are often intertwined, yet they serve distinct purposes within the realm of computing.
Virtualization is a technology that allows multiple operating systems to run on a single physical server or computer. It creates virtual machines (VMs) that can use the resources of the physical hardware to run different operating systems and applications. Virtualization is about maximizing the use of hardware resources by abstracting them and creating multiple isolated environments that can run different operating systems and applications simultaneously.
Cloud Computing, on the other hand, is a model for delivering computing services, where shared resources, software, and data are provided over the internet on-demand. It is a service-oriented model that typically involves over-the-internet provisioning and use of computing power, storage, databases, and other resources. The cloud computing model is based on the idea of pooling resources to serve various customers using a multi-tenant architecture, with services being dynamically allocated and de-allocated as needed.
The key differences between virtualization and cloud computing are as follows:
1. Scope: Virtualization is a technology that can be used in a variety of environments, including data centers, desktops, and development labs. Cloud computing is a service delivery model that can utilize virtualization but is not limited to it.
2. Resource Sharing: In virtualization, resources are shared within a single physical server, but each virtual machine operates independently. In cloud computing, resources are shared across multiple users and can be dynamically allocated and de-allocated based on demand.
3. Access: Virtualization is typically managed and accessed locally within an organization's infrastructure. Cloud computing services are accessed over the internet and can be used by anyone with an internet connection.
4. Service Models: Cloud computing offers various service models such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Virtualization does not inherently provide these service models but can be part of the infrastructure that supports them.
5. Cost: Virtualization can reduce the cost of hardware by consolidating multiple workloads onto fewer physical servers. Cloud computing can reduce costs by eliminating the need for local infrastructure and providing a pay-as-you-go model.
6. Scalability: While virtualization allows for scalability within the limits of the physical hardware, cloud computing offers virtually unlimited scalability as resources can be added or removed from the cloud provider's infrastructure.
7.
Management: Virtualization requires local management of the virtual machines and the underlying hardware. Cloud computing services are managed by the cloud provider, which can offer tools for monitoring, scaling, and maintaining the services.
8.
Security: Virtualization security is managed by the organization itself, while cloud computing security is a shared responsibility between the cloud provider and the user, with the provider typically handling the security of the infrastructure and the user securing their data and applications.
In summary, virtualization is a foundational technology that can be used in various environments to create isolated computing environments, while cloud computing is a service delivery model that leverages shared resources over the internet. Both can work together, as in the case of private clouds, to provide a flexible and scalable computing environment.

"Cloud computing is the delivery of shared computing resources, software or data -- as a service and on-demand through the Internet." Most of the confusion occurs because virtualization and cloud computing work together to provide different types of services, as is the case with private clouds.Jan 20, 2014
