Scientific research as a cloud service

The issues of providing services for scientific research and approaches to the integration of services into the cloud infrastructure are discussed with the provision of a single interface for user access to scientific services to cloud services. An overview and analysis of the known categories of cloud services are presented: “Software as a Service — SaaS”; “Platform as a Service — PaaS”; and “Infrastructure as a Service — IaaS”. The stages of the integration of the scientific service into cloud computing are considered. The stages of the integration of the scientific service into cloud computing are presented. The version of cloud-based IT infrastructure with hypervisor allocation is developed for unified information environment of scientific research. In general, the suggested approaches allow one to introduce and use in practice a new category of cloud services — “Research as a Service — RaaS”.
