Today many talk about how cloud computing is changing the way we view the world. New technologies that simplify our lives, increase operational efficiency, reduce costs and eliminate the headaches are constantly emerging. In fact, today we have so many of them, so it becomes increasingly difficult to keep abreast of them and select the most helpful for themselves.
According to Winter, Raynolds, and Kiss (2014) cloud computing can be defined as a model that provides ubiquitous and convenient network access on demand to the common pool of configurable computing resources (for instance, data networks, servers, data storage devices, applications and services - both together and separately), that can be quickly exempted and provided with low operating costs and / or appeals to the provider. In other words, cloud computing is an innovative technology that combines IT resources from different hardware platforms and allows users to access them via the Internet. However, cloud computing - this is business model, in which the user pays only for the resources he actually consumed.
Cloud computing comes into focus only if you consider what IT always and really needs: a way to raise capability or add abilities on the fly without spending more money in new infrastructure, licensing new software or training new personnel. Cloud computing involves any pay-per-use or subscription-based service that, in real time over the Internet, spreads IT's existing abilities.
Cloud technology appears to be a widely spread and popular topic these days, but it still seems to be confusing and mysterious to the gathering of people, who are non-tech. Cloud computer options are appealing more and more various industries across the world, which is why it is essential to know it is important features as software suggesting. I am going to talk about the five main characteristics that cloud computing is able to offer our business world today.
Resource pooling: The cloud empowers your workers to use and enter data within the business software held in the cloud at the same time, at any time and from any location. This is a striking feature for various field service or business offices and sales teams that are frequently outside the office (Breeding, 2012).
On-demand capabilities: A business will be protected by cloud-hosting services through a cloud host provider that can be your usual software seller. Consumer determines and modifies the computing needs, such as server time, the speed of accessing and processing data, the volume of stored data without interaction with a representative of the service provider You have access to your services and you have the power to change cloud services through an online control panel or directly with the provider. You can add or delete users and change storage networks and software as needed. Typically, you are billed with a pay-for-what-you-use setting or a monthly payment. Terms of payments and expenditures will vary with each software supplier.
Rapid elasticity: Services may be provided, expanded narrowed at any time, without any additional costs for interaction with the supplier, usually in an automatic mode. If anything, the cloud is scalable and flexible and to suit your immediate business needs.
Broad network access: Services are available to consumers through a communications network used irrespective of the terminal device. Your crew can open business management solutions using their tablets, smartphones, office computers and laptops. They can use these devices irrespective of their location, because all they need is just an online access point. Broad network access also embraces private clouds that work within a corporation’s firewall, hybrid deployment or public clouds.
Measured service: Going back to the affordable nature of the cloud, you only pay for what you use. Service provider automatically calculates the consumed resources at a certain level of abstraction (for instance, data storage capacity, bandwidth, number of users, number of transactions), and on the basis of these data, estimates the volume of services provided to consumers. Your cloud provider and you can measure processing, storage levels bandwidth, the number of user accounts and you are billed properly. The amount of resources that you can use can be observed and measured from both your cloud provider’s and your side, which is the transparency that cloud computing provides and ensures.
Basmadjian (2012) discovered that when using cloud computing consumers of information technology can significantly reduce their capital expenditure – costs to build data centers, purchase of server and network equipment, hardware and software solutions to ensure the continuity and efficiency - as the provider of cloud services absorbs these costs. In addition, a long time of construction and commissioning of major infrastructure of information technology and their high initial cost limit consumers' ability to respond flexibly to market demands, while cloud technologies allow almost instantly respond to the increasing demand for computing power.
Thus, wireless devices have altered the way users and organizations interact. Mobile smartphones, laptops, tablets and wireless enabled devices have focused the mindset that wireless networks must be fast, ubiquitous and constantly available. These are demands that have habitually placed organizations and their users in direct contrast with the IT departments, as maintaining and constructing wireless infrastructures have typically been time complex, costly endeavors and consuming.
