The role of operating systems and shells in cloud computing: analysis of OS and shells used in cloud platforms and their impact on cloud infrastructure

The main focus of the article is on operating systems, cloud computing and command shells, which have been actively developing for several decades and are already part of the life of both an ordinary user and a computer technology professional. These objects are considered as separate components of information technology, as well as their relationship and the results of this relationship. Operating systems in cloud servers perform a managerial role. To be more precise, they manage the resources of physical servers. Operating systems or OS in this case define several parameters. These parameters include how operating systems can use and manage memory and storage for various virtual machines. Command shells, in turn, are represented by an application that provides the user with a command-line interface in which he enters commands both individually and runs scripts consisting of a list of commands. Research methods include theoretical (classification, comparative analysis, literature analysis) and practical (experiment, modeling) approaches. This allows for a comprehensive analysis of the functioning of operating systems and command shells in cloud computing. The scientific novelty of our research is the creation of scripts to perform a particular task in the field of cloud computing on a specific operating system using the above-described command shells. Thus, the authors provided theoretical data on operating systems and command shells. The authors provided examples of scripts for Bash and Bourne Shell (sh) command shells for the Linux operating system and scripts for Command Prompt command shells (cmd.exe ) and Windows PowerShell for the Microsoft Windows operating system. As a result of the analysis of the scripts, a table was compiled with the impact of the operating system and the command shell on cloud computing. The analysis of the table allowed the authors to characterize the objects of research of this scientific work and draw appropriate conclusions.
