SECURITY ISSUES AND RELIABILITY CRITERIA OF MULTIPLE CLOUD ENVIRONMENTS

Abstract

The purpose of the given work is to shed light on the critical and actual reliability problems of multi-cloud environments. In this scientific article, we outlined the main problems and reliability criteria of multi-cloud environments for their further analysis. For this purpose, priority mini-problems related to the main problems were highlighted. The work is divided into three small parts, each of which complements each other and fully reveals the subject of the article. In the first part, the problem of multiclouds is described in detail, what is its state, the causes of its occurrence, how relevant the problems are for users of any clouds and why they need to be solved in the near future, and note the considered possible consequences of ignoring them. Also, the connection of problems with practical and scientific tasks was drawn up in order to offer solutions in cases of a combination of cloud products from different providers in the IT infrastructure. In the second part, we got acquainted with the basics of the cloud world and the main providers of the cloud market, using their example, we listed various risks and threats of clouds that caused key reliability problems. In the final third part, the formed criteria of a secure cloud with multicloud are offered to your attention, which can become a guide for choosing a universal method for ensuring the reliability of multicloud or similar systems. Of course, for the uniqueness of the scientific work, a specific goal was given and the well-known works of other figures in the direction of this topic were analyzed. Further details and results can be seen in the conclusions section.
