“…The main goal of training is to determine the structure, knowledge, strategies and values at which European academic programs for primary education of language teachers pay special attention. The best practices were identified, ways of improving existing academic programs were recommended to expand the cooperation of participants in the policy of teaching language teachers [13][14][15][16][17][18][19].…”

Abstract: In the current conditions of society development, the most in demand are the educational level of employees, their professionalism, learning ability, creativity, and high intelligence. This has led to a trend of increasing requirements for graduates of higher education institutions. Taking into account that recent years have been marked by international integration, the quality of training of future philologists should ensure correspondence of all training aspects to the requirements of the applicable standard of education, an adequate level of foreign language command to the extent necessary for the free general and professional communication, the ability to freely navigate in the information field of foreign sources. This study reveals new perspectives and opportunities for the use of electronic educational resources (EER) in education, which allow the use of such effective tools as interactive means, multimedia, communication and productivity.In the process of training, opportunities arise to take advantage of information technologies, including electronic educational resources: electronic textbooks, multimedia, sites, portals, UDACITY and Udemy platforms; Web-2.0 services, new smart technologies, wiki technologies, podcasts, and webinars.

“…Em [Torquato et al 2018] foi proposto uma metodologia de teste de envelhecimento de software denominada SWARE, e posteriormente esta metodologia foi aplicada na plataforma Docker [Torquato and Vieira 2019]. O objetivo da metodologia SWAREé analisar os indicadores de envelhecimento de software e observar os efeitos de ações de rejuvenescimento.…”

Software aging has been a subject explored for almost thirty years. Even with so many years of scientific research, new investigations will be needed due to new technologies. The Docker platform, for example, appeared in 2013 and, although it has been deeply explored, it still needs studies on software aging. Studies show that containers are lighter than virtual machines, however, running many containers can lead to aging. This paper presents a study of aging and rejuvenation of the Docker platform. An experiment was carried out for thirty days, which indicated different levels of aging by varying hardware capacity. We have applied an approach called SWARE. SWARE facilitates the detection of aging signs and rejuvenation effectiveness in a single experiment. Evidences have shown that resource consumption remains high after stopping the workload generation.

“…Liu et al, [22] proposed a novel hybrid aging prediction model named CSSAP which is an integration of autoregressive integrated moving average (ARIMA) model and long short term memory (LSTM) model for cloud services. Several other works in the area are also surveyed [23][24][25][26][27][28][29][30].…”

Cloud Computing is the environment in which several virtual machines (VM) run concurrently on physical machines. The cloud computing infrastructure hosts multiple cloud service segments that communicate with each other using the interfaces. This creates distributed computing environment. During operation, the software systems accumulate errors or garbage that leads to system failure and other hazardous consequences. This status is called software aging. Software aging happens because of memory fragmentation, resource consumption in large scale and accumulation of numerical error. Software aging degrads the performance that may result in system failure. This happens because of premature resource exhaustion. This issue cannot be determined during software testing phase because of the dynamic nature of operation. The errors that cause software aging are of special types. These errors do not disturb the software functionality but target the response time and its environment. This issue is to be resolved only during run time as it occurs because of the dynamic nature of the problem. To alleviate the impact of software aging, software rejuvenation technique is being used. Rejuvenation process reboots the system or re-initiates the softwares. This avoids faults or failure. Software rejuvenation removes accumulated error conditions, frees up deadlocks and defragments operating system resources like memory. Hence, it avoids future failures of system that may happen due to software aging. As service availability is crucial, software rejuvenation is to be carried out at defined schedules without disrupting the service. The presence of Software rejuvenation techniques can make software systems more trustworthy. Software designers are using this concept to improve the quality and reliability of the software. Software aging and rejuvenation has generated a lot of research interest in recent years. This work reviews some of the research works related to detection of software aging and identifies research gaps.
