MODELS OF PRICING OF CLOUD SERVICES

Over the past few years, the paradigm of cloud computing has come into force and became popular in the field of information technology. Many organizations have begun to implement these cloud technologies in order to reduce costs by improving virtualization of machines, reduce administration time and reduce infrastructure costs. As the world's practice shows, cloud technologies are efficient and quite reliable even to provide services to public authorities of most developed world's nations. A similar trend is observed in all countries the EU where the use of cloud computing has become the de facto standard in many areas of socio-economic relations. The paradigm of cloud computing is an integral part of the new industrial revolution and has potential that can provide technological leap to a qualitatively new state of the domestic IT industry, which is very important for the Ukrainian economy. Cloud technologies allow many users to provide services and resources. The emergence of new cloud services leads to an increase in the number of companies that offer various services in the field of cloud infrastructure, and creates a competition of prices in the world market. Cloud providers offer more services to their customers, from infrastructure as a service (IaaS), a platform as a service (PaaS) and software as a service (SaaS). When building and using cloud services, it becomes necessary to make a significant amount of technical, management and financial decisions. The goal of cloud providers is to maximize revenue by their pricing models, while the main goal of consumers is to obtain a high level of quality of services (QoS) at an affordable price. The purpose of this article is to study the features of cloud providers' pricing models, to develop a model for accounting for cloud services and to analyze the main factors that influence the pricing of cloud resources.
