The article is devoted to the research and development of a highly available distributed automated computing system by iterative algorithms based on the microservice architecture in a cloud infrastructure. The subject of the research is the practical foundations of building high-availability automated computing systems based on microservice architecture in a cloud-based distributed infrastructure. The purpose of the article is to develop and to substantiate practical recommendations for the formation of the infrastructure of a high-availability automated computing system based on the microservice architecture, the choice of its constituent elements and their components. The task of the work: to identify the necessary structural elements of a microservice automated computing system and to analyze the constituent components and functional load for each of them, set specific tasks for building each of them and justify the choice of tools for their creation. In the course of the research, methods of system analysis were used to decompose a complex system into elements and each element into functional components, and tools: information technologies Apache Kafka, Kafkacat, Wolfram Mathematica, nginx, Lumen, Telegram, Dropbox, and MySQL. As a result of the study, it was found that the system infrastructure should consist of: fault-tolerant interservice transport, a high-availability computing microservice, and communication microservices with end customers, which save or process the results. For each of them, recommendations are provided regarding the formation and selection of implementation tools. According to the recommendations, one variant of implementation of such system has been developed, the principles of its operation are shown and the results are presented. It has been proven that when using a Kafka queue it is efficient to publish batches of results rather than one at a time, which results to significant overhead on queue servers and data latency for its clients. Recommendations are given on the implementation of the CI/CD system to build a continuous cycle of adding and improving microservices. Conclusions. Practical foundations have been developed for the implementation of high availability distributed automated computing systems based on microservice architecture in a cloud infrastructure. The flexibility in processing the results of such a system is shown due to the possibility of adding microservices and using third-party analytical applications that support connection to the Kafka queue. The economic benefit of using the described system is shown. Future ways of its improvement are given.

The calculations required in project activities for engineering students are commonly performed in electronic spreadsheets. Practice has shown that utilizing those calculations could prove to be quite difficult for students of other fields. One of the causes for such situation (as well as partly for problems observed during Java and C programming languages courses) lies in the lack of a streamlined distribution structure for both the source data and the end results. A solution could be found in utilizing a shared approach for information structuring in spreadsheet and software environment, called “the Book Method”, which takes into account the engineering psychology issues regarding the user friendliness of working with electronic information. This method can be applied at different levels in academic institutions and at teacher training courses.

Purpose The purpose of this study is to critically analyse the concept of unfair dismissal and to assess the extent to which the Employment Rights Act 2008 is affording protection to employees in Mauritius. The purpose of this study is to also demonstrate that as employees form an integral part of their workplace, their employment cannot be terminated without substantive and procedural fairness. The paper will provide some recommendations to cater for loopholes in existing Mauritius employment legislations. Design/Methodology/Approach To critically examine the topic, the black letter approach is adopted to detail legislations and judgments of courts on the subject matter. A comparative analysis with some other jurisdictions’ employment legislations is also carried out to define, explain and examine the concepts of dismissal, substantive causes such as misconduct and procedural fairness. Findings From the methodologies used, it is found that a substantial reason is not sufficient to conclude whether a dismissal is fair. The law of unfair dismissal has introduced some procedural safeguards to protect the employee from being unfairly and unjustifiably dismissed. The procedural requirements act as guidelines to employers and if they are not followed properly, the dismissal will be unfair. Unfair dismissal needs to be accompanied by remedies from employers, and monetary compensation has been found to be the most appropriate remedy. Originality/Value This paper is amongst the first research work conducted in Mauritius that compares the law of unfair dismissal and its implications with the laws of England and South Africa. The study is carried out with a view to provide practical recommendations in this area of employment law to the relevant stakeholders concerned.

The greatest crisis, which is being experienced by the world economy, has not come unexpectedly, since it was predicted with a sufficient degree of precision. Moreover, the matters, causing obstacles for the transformation in the period of transition from the mixed economy to the intellectual economy, have been studied well enough and the technologies of the harmonious transformation have not just been developed but also successfully approbated. However, the crisis is escalating with increasing strength, and many analysts are warning against the risk of irreversible losses, that threaten the mankind with self-destruction due to the effect of 'the lacuna' and 'the gap' between the speed of changes in life conditions and the velocity of growth of human and humanity abilities to adapt to fast changing conditions of ecological, economic, technological and political reality. As anticipated, the main problem turned out to be the intellectual inertia. Despite the fact that the system analysis of the global crisis in education, which does not any longer provide the human and humanity with the proper competencies, even those necessary for the survival, was published by F.G.Coobles back in 1968, the approaches which are long outdated and, therefore, have become dangerous, are still widely spread all over the world. The reports of the Roman club have repeatedly highlighted that the overcoming of 'the lacuna' effect requires new approaches to education, but this has not led to large scale practical results, in spite of the fact, that the task of the development of the new system of the continuous anti-crisis education (for all ages) was accomplished back in the USSR and the experimental model proved to be efficient in process of the 20 years approbation in conditions of the Russian Federation. The psychological bareers arising during the transition from the programme goal method to the system-synergetic approach, from the crisis model of economy to value-sense one, from the subject-object relations to the subject-subject ones and others, have turned to be hard to overcome without the help of specialists, equipped with the methods of the value-sense management, which enable each subject, experiencing the negative impact of the modern economic crisis, to successfully overcome it. This article is dedicated to the peculiarities of the author's scientific-practical school of the value-sense management as a means of overcoming the modern economic crisis.
