Decision-making on the ideal cloud service infrastructures for deploying specific cloud applications is challenging. Goal: Investigation on the performance of cloud infrastructure providers under different load levels. Method: An experimental study evaluated Amazon, Azure, Google, and IBM cloud infrastructure providers in terms of performance under Infrastructure as a Service (IaaS) perspective. Results: The results indicated satisfactory performance in response time and latency among most providers when subjected to up to 300 simultaneous threads. However, this effect decreases as the number of threads increases, and Apdex index value and level of user's satisfaction are significantly reduced under different load levels, mainly for the IBM provider. Besides, the error rate rises substantially at 400 threads, with more critical results for IBM and Amazon providers. Conclusions: Providers show distinct differences across metrics, and the data collected during testings reinforced the potential particularities of cloud infrastructure services for the choice of a provider. Although preliminary, such results can support software companies in selecting a proper infrastructure provider according to particular requirements.","PeriodicalId":6803,"journal":{"name":"2021 XLVII Latin American Computing Conference (CLEI)","volume":"70 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82284679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

JavaScript heretofore was the only built-in language of the web, and unfortunately, it is not well outfitted for the rich applications that have come to dominate the web today. Since its initial release, WebAssembly has made great strides on the web. With the WebAssembly System Interface release in March 2018, which allows WebAssembly to communicate with the operating system, it has become possible to run WebAssembly applications outside web browsers. This paper reviews the current state of WebAssembly and its system interface, describes the costs and benefits of these technologies for applications in different environments, and evaluates performance and portability. Our performance measurements demonstrate that WebAssembly is generally faster than JavaScript and, in some cases, can approach native code performance. Despite its limitations which make WebAssembly useless for specific applications domains, it nevertheless, has the potential to be beneficial in many environments and is likely to grow further even outside its original web environment.","PeriodicalId":6803,"journal":{"name":"2021 XLVII Latin American Computing Conference (CLEI)","volume":"93 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80269817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective was to evaluate the relationship between the dimensions of awareness, compliance and appropriation of the information security culture and the asset protection variable, the ISCA diagnostic instrument was applied, and social engineering techniques were incorporated for this process. The results show the levels of awareness, compliance and appropriation of the university that was considered as a case study, these oscillate between the second and third level of four levels. Similarly, the performance regarding asset protection ranges from low to medium. It was concluded that there is a significant relationship between the variables of the investigation, verifying that of the total types of incidents registered in the study case, approximately 69% are associated with human behavior. As a contribution, an information security culture model was formulated whose main characteristic is a complementary diagnostic process between surveys and social engineering techniques, the model also includes the information security management system, risk management and security incident handling as part of the information security culture ecosystem in an enterprise.","PeriodicalId":6803,"journal":{"name":"2021 XLVII Latin American Computing Conference (CLEI)","volume":"39 5 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82834828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, in particular, we analyze a possible relationship between personality aspects and social interaction mediated by digital platforms. More specifically, we rely on the five personality traits (Extraversion, Agreeableness, Conscientiousness, Emotional Stability and Openness to Experience), commonly referred to as “Big-five”, and associate them to automatically extracted behavioral characteristics derived from the experience of using a Chatbot for a closed community of students at the Universidad Católica “Nuestra Señora de la Asunción” (UC). The personality data comes from a self-report made by the users through questionnaires. The main results show very positive appraisals about the use of the Chatbot in terms of user experience and its main functionalities. As for the role of personality in relation to the main use of the Chatbot, although further experience is required to confirm trends, the results suggest that there are some correlations between some of the five personality traits and the length of questions and answers as well as the selection of best answers.","PeriodicalId":6803,"journal":{"name":"2021 XLVII Latin American Computing Conference (CLEI)","volume":"22 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82750979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
