What is Cloud Computing? Cloud computing is an on-demand provision of computer resources, particularly computer hardware and software, with no direct, active utilization by the user. The phrase is usually employed to describe cloud data centers, available to all internet users over the Internet.
There are two ways to understand the cloud: first, as a virtual machine containing multiple servers that run distinct operating systems, each running specialized applications; and second, as the delivery of infrastructure services over the Internet, such as network connectivity, application deployment, and virtualization. Cloud Computing is poised to change how information is handled in the future.
Users typically access cloud computing services through servers, over the internet or through hybrid infrastructures, such as utilities grids and utility networks. The cloud provides critical IT services when it is needed most and delivers elasticity and performance whenever required. As opposed to on-premises software and other IT solutions that are purchased and managed, cloud computing delivers on demand resources when users have activated those services. Furthermore, cloud services deliver consistent and guaranteed resource allocation, security, scalability, and redundancy. Cloud service providers usually serve as the intermediary between users and IT services.
What Is Cloud Computing? Today, Cloud Computing is very much a part of the lifestyle of modern business people. Business meetings, product demonstrations, product launches, company social visits and employee training are some of the most typical uses of cloud computing services. In addition, many companies use the cloud storage services and webmail for internal activities such as collaboration and task management. However, in this article, we will discuss the main question: What is Cloud Computing?
A Cloud is basically a collection of resources that may be stored, analyzed, retrieved and shared and the service provider only charges for the usage of these resources when it is used. The main characteristic of a cloud is its ability to scale up and down easily without the need for a significant impact to its users’ infrastructure. Cloud Computing helps to create elasticity by leveraging multiple on-demand accesses to the same data at the same time reducing the need for purchasing storage capacity, bandwidth and power. Cloud storage also allows users to access data across the internet, thereby eliminating the need for data centers and other hardware.
On-demand access refers to the ability for a user to make use of his own virtualization tools without having to purchase additional infrastructure or software. Virtualization is a general term that refers to the set of techniques that enable different virtual environments. Examples include operating system virtualization, client virtualization, platform virtualization, cloud, private, converged virtualization, and hybrid virtualization. Cloud computing helps to provide users with improved functionality by providing them with software and hardware resources on demand. It also makes it easy for organizations to adopt new technologies without investing a significant amount of capital into the r&d.
Cloud hosting is software that hosts applications on the Internet. It provides users with multiple computing resources on demand. Cloud platform provides the user with the ability to acquire and make use of cloud-computing tools such as applications, database, and storage without needing to invest in server applications. In short, a cloud platform is software that makes it easy for users to develop and deploy applications and data without the need for purchasing, maintaining and managing a data center.
A cloud service is a service that many customers require and all of which are provided by a single provider. A national institute is an example of a company that uses a cloud platform to host all of its computer servers. The advantage of using this kind of service provider is that they are able to control and monitor their servers from remote locations. A customer looking to buy a server from a national institute should ensure that the provider offers the services that the customer requires.
Hybrid clouds refers to clouds where a company will use technology that is virtual but the hardware will be based on the public cloud or other specialized clouds. Hybrid clouds are becoming increasingly important because of their ability to make the most of the resources that are offered to the customer. While the initial expense of this type of cloud computing can be high, many companies find that their operational expenses do not vary as much as their IT costs.
