Bonjour tout le monde,
Bonne et heureuse année !
Dans le cadre des séminaires de l'équipe Sécurité /Systèmes, nous écouterons sur Teams
Jean Araujo, chercheur à l'université fédérale de Sergipe, Brazil, jeudi 11/01/2024 à
16h30.
Jean Araujo nous parlera de ses travaux sur "Impacts of Software Aging Issues and
Rejuvenation Strategies in Computing Systems".
Résumé :
In today's connected world, software is required to operate for long periods and must
be tolerant to various types of faults that may affect its functioning properly. A major
threat to the performance and availability of computing systems is the phenomenon known as
software aging, an inevitable phenomenon where application processes suffer performance
degradation throughout usage. Some proactive actions should be taken to minimize aging
effects, but these solutions (i.e., software rejuvenation) are particular to each
environment under analysis. Software Aging and Rejuvenation (SAR) has gained importance in
recent years as software systems have become more complex and critical to the operation of
many organizations. SAR techniques have sought for software systems to remain reliable and
work well for long periods, especially in systems requiring high performance and
availability levels.
Bio :
Jean Araujo received his PhD in Computer Science from the Universidade Federal de
Pernambuco, Brazil (2017). He was a professor at the Universidade Federal Rural de
Pernambuco from 2013 to 2019. Since 2019 he has been a professor at the Universidade
Federal do Agreste de Pernambuco, and since 2022 he has been a researcher at the Computer
Science post-graduation program at the Universidade Federal de Sergipe, Brazil. His
research interests include software aging and rejuvenation, performance, availability,
reliability, and stochastic modelling, which covers applied areas such as cloud computing
and virtualized systems. He has published more than 100 papers in peer-reviewed journals
and international conferences on computer science topics.
