Cloud Computing is an approach to shared virtualization and centralizing resources via the Internet, to provide IT services. The term is generally applied to describe online data centers, accessible to multiple users over the Internet, with no need for direct human supervision. It is used in various contexts, from network management to e-business. One of the biggest advantages of using this technology is that it helps in reducing costs, which otherwise become a huge expense for most companies. The Cloud also helps in managing and protecting critical business applications. Take a look at this link: hivecell.com for more understanding about this topic . Today, there are two forms of Cloud: public and private. The former refers to shared resources that are provided to a number of customers for a particular period of time and for a specified amount of money. A company can use the public cloud services for its applications and data storage requirements. However, a company that requires more capacity or better security than the offered public cloud services can use private cloud services, within parameters dictated by their own internal needs. The cloud computing concept enables easy application deployment. It also reduces IT costs by providing centralizing data storage, processing, memory, and bandwidth. There are three types of Cloud: the public, private, and hybrid clouds. The most common form of public Cloud is the public cloud, which is usually offered by a hosted services provider (HPS), to customers for a specific period of time and at a fixed price. These offer great flexibility to organizations, as they allow you to use the infrastructure for any purpose that you require at a lower cost. Private clouds are typically less expensive and more flexible than public Cloud. They provide all the services that a private Cloud would, at a much higher cost. However, they have less reach and are not elastic. Hybrid clouds are a combination of public and private Cloud, with some components dedicated to one or the other and some elements based on a hybrid model. This Cloud allows users to use both the advantages of Cloud computing, with the advantage of centralization of servers and application deployment. Hybrid clouds offer cost savings and better flexibility for businesses. Please visit this site for more knowledge about this topic . On the other hand, there are three distinct limitations of cloud services. They include the limitation of applications being available anywhere, the constraint of applications being able to access each other's data, and the limitation of shared data. The availability of the data means that a business may be able to obtain as much storage as they need, at the expense of paying for it in a centralized manner. This is a common practice within enterprises that require a lot of storage and data management services, like call centers and financial or medical record management. A Cloud service provider offers several options for application deployment. These include infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and self-service (SaaS). IaaS is a web-based model that allows users to easily deploy applications using an abstraction layer and software as a service. PaaS and SaaS are fully-virtualized server environments with extensive user and system control. The self-service option allows users to easily install and utilize a variety of virtual servers running on the provider's infrastructure. The cost savings with a Cloud service can be considerably improved when utilizing such a model compared to traditional methods of infrastructure investment.
