The evolution of cloud computing is driving the next generation of internet services. OpenStack is one of the largest open-source cloud computing middleware development communities. Currently, OpenStack supports platform specific signatures and tokens for user authentication. In this thesis, we aim to introduce a platform independent, flexible,and decentralized authentication mechanism in OpenStack. We selected OpenID as an open-source authentication platform. It allows a decentralized framework for user authentication. OpenID has its own advantages for web services, which include improvements in usability and seamless SSO experience for the users. This thesis presents the OpenID-Authentication-as-a-Service APIs in OpenStack for front-end GUI servers, and performs the authentication in the back-end at a single Policy Decision Point. The design was implemented in OpenStack, allowing users to use their OpenID Identifiers from standard OpenID providers and log into the Dashboard/Django- Nova graphical interface of OpenStack. / Utvecklingen av molndatabearbetning är drivande nästa generation av Internet-tjänster. OpenStack är en av de största öppen källkod mellanprogramvara datormoln utveckling samhällen. För närvarande stöder ITplattform specifika signaturer och pollett som för användarautentisering. I denna avhandling vill vi införa en plattformsoberoende, flexibel och decentraliserad autentiseringsmekanism i OpenStack. Vi valde OpenID som en öppen källkod autentisering plattform. Det möjliggör en decentraliserad ram för användarautentisering. OpenID har sina fördelar för webbtjänster, som omfattar förbättringar i användbarhet och sömlös SSO-upplevelse för användarna. Denna avhandling presenterar de OpenID-Autentisering-as-a-Service APIer i OpenStack för front-end GUI servrar och utför autentisering i back-end i ett enda politiskt beslut punkt. Designen genomfördes i OpenStack, så att användarna kan använda sina OpenID kännetecken från standarden OpenID leverantörer och logga in på Dashboard / Django-Nova grafiskt gränssnitt av OpenStack.

[pt] A pesquisa traz reflexões acerca da chamada Nova Geração do samba no Rio de Janeiro, destacada, especialmente, pelas rodas de samba no Beco do Rato, bar localizado entre os bairros da Glória e da Lapa, e também a partir da elaboração do DVD Samba Social Clube - Nova geração, Vol 1., em 2016, e o DVD Samba Social Clube - Nova geração, Vol 2., lançado em 2020. Deste modo, aprofunda-se o debate pelo vetor da inserção, dessa categoria, na cena musical, a fim de compreender suas sonoridades, repertório, as rotinas de trabalho e a relação com as demandas sociais contemporâneas como machismo, racismo e homofobia. Por fim, analisa-se como o apadrinhamento está presente na trajetória desses músicos, explorando as relações e parcerias com nomes célebres do samba, a herança familiar e outros sentidos possíveis nestas articulações. / [en] The research brings reflections on the so-called New Generation of samba in Rio de Janeiro, highlighted, especially, by the wheels of samba in the Alley of the Mouse, bar located between the neighborhoods of Gloria and Lapa, and also from the elaboration of the DVD Samba Social Club - New generation, Vol 1., in 2016, and the DVD Samba Social Club - New generation, Vol 2., released in 2020. In this way, the debate is deepened by the vector of the inclusion of this category in the musical scene, in order to understand its sonorities, repertoire, work routines and the relationship with contemporary social demands such as machismo, racism and homophobia. Finally, it is analyzed how the sponsorship is present in the trajectory of these musicians, exploring the relationships and partnerships with famous names of the samba, the family heritage and other possible senses in these joints.

[pt] Partindo da premissa de que Design é o processo de pensamento que compreende a criação de alguma coisa (Miller, 1988), realizei uma pesquisa-ação participante com alunos do terceiro período da graduação em Comunicação Social da Pontifícia Universidade Católica do Rio de Janeiro, sobre processos interativos de ensino-aprendizagem vinculados às Novas Tecnologias Digitais de Informação e Comunicação (NTDICs). Como professor regente de três turmas da disciplina Técnicas de Comunicação II, desenvolvi, como ferramenta de mediação, o professortexto.blog, uma interface digital de interação entre professor e alunos participantes. O presente trabalho descreve e analisa a experiência interdisciplinar vivida pelos participantes em sala de aula presencial e virtual, simultaneamente. E conclui que professores gestores das NTDICs exercem a função de designers cognitivos a projetar e manter pontes dialógicas para orientar projetos e direcionar pesquisas que os universitários terão que produzir para conhecer. / [en] Starting from the premise that design is a thinking process comprising the creation of an entity, according to Miller (1988), I have conducted a participatory research with third semester undergraduate students of Social Communications at the Pontifical Catholic University of Rio de Janeiro . The research is focused on interactive processes of teaching/learning linked to the New Digital Technologies for Information and Communication (NTDICs). As a professor of three classes of Communication Skills II, I have developed the professortexto.blog as a mediation tool, which has provided me with a digital interface to interact with my students. This work describes and analyzes the interdisciplinary experience lived, simultaneously, by the participants in the classroom and virtual ly. It concludes that teachers who manage NTDICs play the role of cognitive designers as they are supposed to plan and maintain dialogical bridges to guide and direct the students’ research projects in order to develop their knowledge.
