Replicabilidade e escalabilidade. + + 2. Capacidade de combinação rizomática. + + 3. Regeneração e reagrupamento após eventos catastróficos. + +A Hidra moderna pode resistir a Hércules. + +Parte 2: Grupos Técnicos Sociais +================================ + +Mas antes façamos uma retrospectiva... + +Sistemas informacionais sociais +=============================== + +Modelo "clássico" de hospedagem: arquitetura "cliente-servidor": + +<div class="centered" markdown="1"> + +</div> + +Trabalho técnico informacional em grupos sociais +================================================ + +Características: + + - Considerado tecnicamente de alta dificuldade e dedicação. + + - Esforço para provisionamento, configuração e manutenção de sistemas. + + - Trabalho demorado: escala de meses para alcançar estabilidade. + + - Suscetível a muitas falhas: escala de horas para que um sistema seja inutilizado. + + - Pouco tempo disponível para o trabalho. + + - Dificuldade para a realização de backups e manutenção de procedimentos administrativos. + + - Baixa mobilização e força de trabalho "tarefeira". + + - Custa um bom dinheiro... + +Interlúdio: a destruição das redes +================================== + + + + +A cada evento catastrófico, vários grupos são prejudicados com danos à comunicação de difícil cicatrização. + +Parte 3: Contra-ataque infraestrutural +====================================== + +Como impedir que uma rede seja destruída mesmo que a remoção de nodos continue? + +A divisão em camadas +==================== + +Observação crucial: + + "Ghost in the shell": o disco e o hardware são intercambiáveis, + provisionamento pode ocorrer em múltiplas etapas. É possível + manter um estoque de discos pré-instalados e uma reserva financeira + para a aquisição de máquinas. Isso e backups permite a reconstrução + de sistemas. + +Conclusão imediata: + + É necessário "descolar" a camada de serviços (web, streaming, email, + etc) da camada infraestrutural (máquinas, conexões, etc): filtragem + de problemas físicos e jurídicos. + +A camada de serviços pode então ser "congelada" na forma de backups, enquanto que a camada infraestrutural não possui "alma" intrínseca, podendo ser reconfigurada quando necessário. Desse modo, várias máquinas podem ser mantidas no ar para aumentar a tolerância a falhas. + +Mas como um sítio pode estar simultaneamente em várias máquinas? + +DNS: colando domínios em máquinas +================================= + + + + +O colamento/descolamento entre camadas é possível mediante mudanças de DNS. + +Proxies: distribuindo um sítio entre máquinas +============================================= + +<div class="centered" markdown="1"> + +</div> + +Aplicação descentralizada ou distribuída +======================================== + +<div class="centered" markdown="1"> + +</div> + +Tipos de camadas +================ + +Informação de um sistema é dividida conforme sua aplicabilidade: + + - Hardware: manifestações cristalizadas de informação: computadores. + + - Programas (software): pacotes. + + - Configuração (módulos). + + - Chaves e senhas. + + - Dados (o conteúdo propriamente dito). + +Tais camadas podem ser empacotadas em sistemas e tais sistemas podem ser agregados em outros sistemas (camadas de camadas de camadas): pode ser uma abstração complicada, mas o ganho conceitual em isolamento de instâncias é importante. + +Problemas +========= + +O discurso é bonito, porém... + + 1. Hardware é muito heterogêneo para padronizações serem efetivas. + + 2. Os programas são muito diversos para serem estudados, integrados e desenvolvidos. + + 3. Configurações são muito complexas e numerosas para serem facilmente separadas e replicadas de forma genérica. + + 4. São necessárias muitas senhas de boa complexidade, o que torna sua manutenção complicada. + + 5. Backups são difíceis de serem realizados e recuperados. + +Ou seja: o discurso da divisão em camadas é interessante, porém na realidade sua implementação enfrenta diversos problemas. Serão eles impeditivos? + +O Plano R* +========== + + + + +O Plano R*: email +================= + +<div class="centered" markdown="1"> + +</div> + +Como é possível? +================ + +O segredo está na articulação da força de trabalho com a divisão de camadas. A regra geral é: + + 1. Utilização de ferramentas sólidas e amplamente utilizadas por comunidades de software livre e aberto. + 2. Trabalho de desenvolvimento focado na integração de soluções existentes, enviando alterações em código corrente acima sempre que possível. + 3. Desenvolvendo código próprio, porém livre, apenas quando não existente ou insuficiente nas comunidades. + +Cada um desdes tipos informacionais é distribuído em unidades que por sua vez são agregados em árvores: + + - Hardware em servidores (canalizadores de fluxos, nodos ou instâncias em nuvens). + - Programas em pacotes e distribuições. + - Configurações em módulos e repositórios. + - Chaves (que são unidades de segredo) em repositórios. + - Dados em árvore de backups. + +Divisão artefática +================== + +A divisão em camadas é artificial (artefática), porém com importantes consequências quando observada à luz da divisão do trabalho de comunidades de software livre e aberto: + + /'\ | + | \./ + upstream downstream + + - Hardware: desenvolvimento caro e complexo; hardware livre e aberto engatinhando; dependência do mercado. Exemplo: disco rígido. + - Programas e distribuições: grandes comunidades de desenvolvimento e uso. Exemplo: GNU/Linux, Debian. + - Configuração: comunidades mais restritas de desenvolvimento e uso. Exemplo: manuais, howtos, módulos. + - Chaves e senhas: restrita ao grupo responsável por manter uma dada infraestrutura. Exemplo: senha de superusuário/a. + - Dados: desenvolvidos pelas pessoas e grupos hospedados. Exemplo: texto num wiki. + +Divisão artefática - 2 +====================== + +É possível reconstruir um sistema dados esses elementos. A divisão do trabalho upstream/downstream é favorável à reconstrução, já que as tarefas se tornam mais complexas ao longo da subida da corrente onde usualmente os grandes grupos sociais se reúnem para solucioná-las. + +Economia de trabalho +==================== + +Assim, é possível economizar muita força de trabalho. + + 1. Enviar um desenvolvimento corrente acima (upstream) libera o grupo técnico de uma manutenção posterior, pois o trabalho passa a ser de responsabilidade da comunidades mais ampla. + + 2. Quanto mais específica for a informação, mais abaixo da corrente (downstream) ela deve ser mantida. + + 3. Naquilo que não houver desenvolvimento corrente acima, atuar como fonte (ou seja, agir como upstream) e fornecer para a comunidade. + +Tipos de salvaguarda +==================== + +Para todas as camadas divididas anteriormente é possível criar algum tipo de salvaguarda contra perdas: + + - Dinheiro: armazenamento e replicação de força de trabalho (potencial de trabalho armazenado). + + - Estoque: hardware hoje é commodity, podendo ser minimamente estocado ou mantido online em diversos locais. + + - Repositórios: programas, pacotes, distribuições e configurações. + + - Backups: manutenção de dados ou coisas sobressalentes. + +Parte 3: contexto brasileiro +============================ + +Orçamento e infraestrutura +========================== + +Custos: + + - Plano R*: EUR 10.000 anuais. + - No Brasil, é praticamente a despesa anual de um centro social alugado e muito mais do que a receita da maioria dos grupos. + +Conexão: + + - Nos EUA e na Europa, a conexão é rápida e barata. Datacenters corporativos são acessíveis. + - No Brasil, a conexão é lenta, cara e o preço dos datacenters é exorbitante. + +Repressão: + + - Criminalização dos movimentos sociais (entulho jurídico). + - Polícia violenta. + +Estaremos impossibilitados/as de mantermos servidores no país? + +Por outro lado +============== + + - A legislação, a jurisprudência, cultura e valores brasileiros são muito mais favoráveis à preservação da privacidade que nos EUA ou na Europa (fator Dantas). + + - Honorários advocatícios não são tão altos quanto no exterior (?). + + - O câmbio é favorável a doações internacionais. + +O caso Satangoss +================ + +"O que demorou quatro anos para juntarmos nos foi arrebatado num único dia." + + - Agosto de 2008: polícia civil apreende o servidor do Saravá sem mandado judicial. + + - Mais de cem sítios fora do ar. + + - Não havia backup remoto e nem medidas de contingência estabelecidas. + + - Todos os ovos estavam na mesma cesta. + + - Grande desmobilização. + + - Análise do caso: http://www.sarava.org/node/44 + +Como reverter a crise num novo ciclo de mudança e amadurecimento? + +Parte 4: O Processo Hidra +========================= + +<div class="centered" markdown="1"> + +</div> + +Regeneração +=========== + +Hidra: toda célula pode ter o germe da própria organização.

O padrão foi desenvolvido para: + + - Ter controle dos pacotes utilizados, arquivos de configuração e serviços em uso. + + - Uniformidade de administração. + + - Sistema de gerenciamento de backups comum para que as máquinas de um projeto possam trocar dados. + + - Que um servidor seja configurado apenas uma vez e que suas configurações possam ser aproveitados para outras máquinas. + + - Que sites e serviços sejam armazenados de maneira regular para facilitar atualizações e migrações. + + - Manter projetos e serviços isolados uns dos outros através de servidores virtuais. + + - Tornar a instalação dos servidores facilmente replicável. + +Dinâmica de desenvolvimento: + + Documentação wiki -> Configurações pré-gravadas -> Software + +Puppet +====== + + + + +Puppet: compartilhando configuração +=================================== + +Código puppet: + + file { '/etc/passwd': + owner => root, + group => root, + mode => 644, + } + +Módulos compartilhados: + + - [http://git.sarava.org](http://git.sarava.org) + + - [https://labs.riseup.net/code/projects/sharedpuppetmodules](https://labs.riseup.net/code/projects/sharedpuppetmodules) + +Git e gitosis +============= + + + + +O Protocolo de Compartilhamento de Recursos +=========================================== + + "The Resource Sharing Protocol (RSP) is a set of metadata intended to help free + software groups + + * Share their available resources and also Find groups that can host + * services for them given their needs and requirements. + + The RSP splits each resource in a layer or set of service layers.

A existência de múltiplas cópias integrais do wiki (online e offline). + 2. Desenvolvimento distribuído de documentação. + +O ikiwiki é muito útil para reunir documentação de sistemas, já que não necessita de nenhum sistema web funcional para abrigá-la. + +Virtualização +============= + +Virtualização através de Linux-VServer (existem outras implementações possíveis): + + - [http://www.linux-vserver.org](http://www.linux-vserver.org) + - [http://slack.sarava.org/vservers](http://slack.sarava.org/vservers) + +Principais vantagens: + + - Permite diversos grupos compartilharem uma mesma máquina presevando sua autonomia. + + - Grupos podem hospedar mutuamente instâncias virtuais. Exemplo: se existem 5 grupos com uma máquina cada um, se cada um deles hospedar um vserver para cada grupo, teremos 4 locais remotos de hospedagem por grupo, aumentando assim as possibilidades de salvaguarda e escalabilidade. + +Keyringer e monkeysphere +======================== + +O Keyringer ([http://git.sarava.org/?p=keyringer.git;a=summary](http://git.sarava.org/?p=keyringer.git;a=summary)) é um repositório distribuído de senhas/chaves baseado em GPG e git. + +O monkeysphere ([http://web.monkeysphere.info](http://web.monkeysphere.info)) é um programa que permite a verificação de hosts SSH e usuários/as através da Teia de Confiabilidade do OpenPGP.

O processo já ocorre em vários locais. + + - Havendo várias hidras, se elas se integram passa a existir a Confederação das Hidras Unidas. + + - Importante questão do licenciamento: AGPL 3.0 para garantir o máximo possível da disponibilização de código e documentação. + + - Não é estritamente necessária a criação de uma "confederação", já que a cultura de hidras pode ser não-coordenada. + +Parte 7: Nuvens e Hidras +======================== + +Hidras são nuvens (cloud computing)? + + - Cloud computing foca apenas nas instâncias e como estas são integradas por aplicações (IaaS, SaaS, PaaS) e no seu uso sob demanda. + + - Cloud computing é uma iniciativa do mercado e uma tendência à terceirização total das atividades. + + - A Hidra leva em consideração a organização social que suporta a infraestrutura computacional. + + - A Hidra é uma nuvem na qual certos nodos desempenham papéis determinados, porém contendo o germe de toda a organização. + + - Outra classe de nuvens: botnets. + +Nuvens: diagramas +================= + + + + +Tipos de nuvens +=============== + +<div class="centered" markdown="1"> + +</div> + +Parte 8: Futuro +=============== + + - Hidra Saraventa: ainda em intenso desenvolvimento, porém já em estágio maduro.

No entanto, em geral são as redes distribuídas e descentralizadas que possuem fatores de regeneração maiores do que no caso centralizado. + + - Número grande de máquinas é interessante: várias podem estar sem funcionar num dado momento, mas as que estiverem funcionando podem dar conta da demanda. + + - A hidra é indestrutível?
