Cloud Computing
The term "moving to cloud" also refers to an organization moving away from a traditional CAPEX model (buy the dedicated hardware and depreciate it over a period of time) to the OPEX model (use a shared cloud infrastructure and pay as one uses it)
Cloud computing adopts concepts from Service-oriented Architecture (SOA) that can help the user break these problems into services that can be integrated to provide a solution. Cloud computing provides all of its resources as services, and makes use of the well-established standards and best practices gained in the domain of SOA to allow global and easy access to cloud services in a standardized way.
The definition of infrastructure as a service (IaaS) is pretty simple.
You rent cloud infrastructure—servers, storage and networking—on demand, in a pay-as-you-go model. IaaS is the fastest growing area of cloud computing . Enterprise public cloud spending is expected to reach $207 billion
Common public IaaS workloads: Dev/test, Website hosting, Storage, Simple application development
Common managed IaaS workloads: Analytics, Big Data, SAP and other enterprise applications
virtualization is simply one of the elements that makes cloud computing.To continue this analogue, cloud computing can happen without virtualization. Certain hardware, operating system and even application clusters can deliver cloud services.
The more likely scenario is that a private cloud computing environment is built on a virtual infrastructure. Many organizations have deployed virtualization by creating virtual servers on top of their existing networking, storage and security stacks. But with private cloud computing, you need to think about and design these technologies in conjunction with one another.
In other words, you built previous virtual infrastructures on these stacks, but you need to
build a private cloud with these stacks.
Private cloud computing does not center on virtualization or any one technology. It uses a set of technologies that have been aligned to be highly flexible and provide a wide range of services. This approach does not require virtualization, but virtualization does lend well to the core concepts of cloud computing.
Virtualization and cloud computing are also so closely connected because the major hypervisor vendors -- VMware, Microsoft and Citrix Systems -- are putting a lot of emphasis on the cloud. They have closely aligned their products with tools and complementary technologies that promote the adoption of private cloud computing.
Cloud computing is a rapidly evolving discipline, and one that will reshape org charts as fast as it will change data center layouts. It closely aligns with virtualization, but it takes many technologies to be successful.
The simple answer is yes, the private cloud model is starting to resonate with organizations designing (or redesigning) data centers. CIOs realize that pooled resources with a virtualization layer allows for greater flexibility and efficiency -- and should be more cost effective.
The ultimate goal is to move to the public cloud as much as possible, because there should be greater cost savings thanks to higher utilization levels. Enterprises are trying to find the right balance between the two types of clouds, and private clouds are a great first step on the journey to the public cloud. until regulators for certain industries like financial and medical institutions are able to set detailed, certifiable, guidelines to public cloud providers, We can see more growth in private clouds.
A private cloud means "your virtual machines exist somewhere on the network." That network is "your LAN." And the resources used to create that cloud are "elastic ," growing and shrinking to meet the demands of your virtual workloads.

What exactly is the difference between virtualization and private cloud computing?
The best way to explain the difference between virtualization and cloud computing is to say that the former is a technology, while the latter is a service whose foundation is formed by said technology.virtualization is simply one of the elements that makes cloud computing.To continue this analogue, cloud computing can happen without virtualization. Certain hardware, operating system and even application clusters can deliver cloud services.
The more likely scenario is that a private cloud computing environment is built on a virtual infrastructure.
