Cloud computing is the on Demand availability of computer network resources, particularly computer processing power and storage, without direct user management. Cloud is a general term to describe any computer resources that are not stored in a single server but can be accessed from any remote location. In a cloud, data is hosted in a distributed environment without requiring the actual machine to be offline. The term cloud is often used to describe either a network of remote servers, a collection of data centers, or a collection of virtual machines at hivecell.com.
There are three basic deployment models of private cloud computing. The first model is called the end-to-end model, in which each customer's data is stored in its own cloud, and applications are deployed as needed. This is the fastest type of cloud computing, and it requires the least amount of customization. The second model, also called the infrastructure-as-a-service (IaaS) model, consists of a private network of servers that serve as the backbone for a business's web services. This model relies on the Internet to deliver requested data to the appropriate application.
The third deployment model, called the virtual cloud environment, substitutes a physical machine with virtualization technologies. Virtualization allows multiple devices to share the same operating system and resources, such as a laptop running Windows versus a laptop using the Linux OS. VDI or virtualized desktop is another approach that reduces the need for hardware investments. With VDI, a user has the convenience of being able to utilize a different operating system on a laptop that shares the same monitor and keyboard. This allows the use of a virtual keyboard, mouse, and display, while keeping costs low.

Different providers offer cloud computing services at https://hivecell.com/. Compose offers platform-as-a-service (PaaS) and cloud services. Its PaaS offerings include software development, infrastructure management, product development, and website development. Cloud services are delivered via software applications. Amazon, the largest cloud services provider in the world, offers its Ecommerce infrastructure using infrastructure from various companies including IBM, Microsoft, and Citrix.
Public clouds are offered by companies that do not use private clouds to provide their cloud services. Examples of public cloud computing companies include Google, which offers two major public clouds, infrastructure-as-a-service (IaaS) and cloud development-as-a-service (cats). A major advantage of public-cloud services is lower costs. By choosing to use public clouds, companies reduce costs by avoiding purchasing costly hardware and software licenses. They also do not incur expenses such as software licenses, maintenance fees, and service call charges.
Aside from these three main types of cloud computing services, there are also a number of subtypes. For instance, software as a service (SaaS), has become very popular over the past five years because it can be used in a number of different ways, ranging from delivering software to managing infrastructure. Platform as a service is another type of cloud provider. This type of service provider provides web applications to end users through the Internet, but instead of storing the applications on servers, it operates within the client's browser.
