What is the difference between cloud computing and virtualization?

Hello, Cloud computing is the term utilised to indicate that the user is using services provided by someone else for his benefit albeit at a price for use of such hardware. It's something like polyclinic in a city where one entrepreneur provides facilities like comfortable rooms, receptionists, cleaning, nursing, electricity and water etc. Specialist doctors just come and occupy their room and start examination of patients. No need for such doctors to invest in buying building and spending time on each and everything that is required to make an OPD functional. In cloud computing, entrepreneurs need not bother about storage space, specs if hardware etc. It is provided by another company providing cloud services.Virtualization on the other hand means it's something that is actually not. For example: a computer that we operate on Windows may allow a part of it to run on Linux thus creating a compartment virtually since computer is same.

Virtualization can increase IT agility, flexibility and scalability while creating significant cost savings. Workloads get deployed faster, performance and availability increases and operations become automated, resulting in IT that's simpler to manage and less costly to own and operate. Large enterprises have huge data centers. IT organizations of large enterprises are challenged by the limitations of today x86 servers, which are designed to run just one operating system and application at a time. As a result, even small data centers have to deploy many servers, each operating at just 5 to 15 percent of capacity, which is highly inefficient by any standard. Therefore, companies are resorting to virtualisation to increase efficiency and cost saving. Cloud computing is not the same thing as virtualization; rather, its something you can do using virtualization. Cloud computing describes the delivery of shared computing resources (software and/or data) on demand through the Internet. Whether or not you are in the cloud, you can start by virtualizing your servers and then move to cloud computing for even more agility and increased self-service.

1. Cloud Computing : A client-server model underpins cloud computing. As a highly accessible service, cloud computing makes use of resources in a centralized manner. Using cloud computing is a subscription-based service and a beneficial business tool. 2. Virtualization: The foundation for cloud computing has been laid through virtualization. It is this uniqueness that enables a continuous asset life cycle from particular eccentric circumstances or a single physical device framework. As a result, a hypervisor plays a critical role in creating a small number of virtual computers using the hardware. It's easy to SEE these virtual machines at work since they are autonomous and don't interfere with one another. In the event of a calamity, a single peripheral device and a single piece of specialised hardware are all that is required.

Virtualization is software that separates physical infrastructures to create various dedicated resources. It is the fundamental technology that powers cloud computing. Virtualization is a foundational element of cloud computing and helps deliver on the value of cloud computing. Cloud computing is the delivery of shared computing resources, software or data as a service and on-demand through the Internet. The cloud can, and most often does, include virtualization products to deliver the compute service. The difference is that a true cloud provides the self-service capability, elasticity, automated management, scalability, and pay-as-you-go service that is not inherent in virtualization.

Cloud computing is basically a provision of services like infrastructure, platform and software to clients for management of data and all applications. Cloud helps in storage of end to end data and gives a competitive edge in terms of providing analytics for business decisions. Virtualization involves a conversion of hardware to software via wireless sensors and operated through a software-defined network. Virtualization replaces the need for all dedicated hardware like routers, firewalls and switches. The difference is in the execution of both technology, else the similarity is only in terms of compatibility. Various companies provide both cloud computing and virtualization viz. Ericsson, Huawei, ZTE, Nokia, Cisco, Samsung, IBM. The business cases are abundant and help the organization save ample of cost and help them generate additional revenue opportunities.

Hello, At first, it may seems that virtualization and cloud computing are both same. But they are both different apart. Virtualization is simply replacing the physical resources with the virtual one without affecting its principals and working. Network virtualization is the closest type of virtualization to the kinds of setups known as cloud computing. In network virtualization, individual servers and other components are replaced by logical identifiers, rather than physical hardware pieces. On the other hand, cloud computing technology is a more specifically an IT model which constitutes computer software and hardware materials for sending data through wireless or IP address connected computer system. To conclude this difference, cloud computing is a reference to specific kinds of vendor-provided network setups, where virtualization is the more general process of replacing tangible devices and controls with a system where software manages more of a networks processes.

In computing, virtualization refers to the act of creating a virtual (rather than actual) version of something, including virtual computer hardware platforms, storage devices and computer network resources. Virtualization can increase IT agility, flexibility and scalability while creating significant cost savings. Workloads get deployed faster, performance and availability increases and operations become automated, resulting in IT that's simpler to manage and less costly to own and operate. Large enterprises have huge data centers. IT organizations of large enterprises are challenged by the limitations of today’s x86 servers, which are designed to run just one operating system and application at a time.
