Crescer é um processo complicado e doloroso! É impossível de se prever com precisão Existem gargalos escondidos Às vezes você precisa voltar atrás Às vezes você precisa mudar tudo Não existem “silver-bullets” A complexidade vai crescer com você

Crescimento real nunca acontece em um só eixo! Tráfego : mais usuários, transações, imagens... Tamanho : banco, memória, cache... Complexidade : algoritmos, arquitetura, infraestrutura... Organização : equipe, comunicação, processos... Negócio : modelos, parceiros, fornecedores... Na maioria dos casos os problemas crescem mais que linearmente!!!

Active DNA Problema: Várias features necessárias (Proﬁle, SSO, Avatar, etc) e pouco tempo Serendipity: Companhia irmã com vários componentes REST Resultado: Active DNA, uma biblioteca REST ﬂexível mais cache e serviços

Active DNA Por que não Active Resource Interface ﬁxa Somente Rails sem overrides Pouca integração com external services

Busca Ferret: FAIL Sphinx: Muito limitado Lucene / Solr: Java Xapian: Interessante Mas, e se precisarmos mudar?

Busca Solução: Sapien Cliente / encapsulamento de servidor de busca Driver-based, naturalmente distribuído Drivers podem ser mudados e o índice refeito em um passo Brasigo Query Language

API Controle de Acesso HTTP Auth (email & senha) OAuth para suportar usuários de OpenID e outros Restrições de uso Frameworks mais leves Sinatra Thin

Dia-a-dia (SCRUM) Scrum Várias equipes Coordenação e priorização Rotacionamento de equipes Socialização de conhecimento Cultura compartilhada

Dia-a-dia (Git) Git Vários repositórios internos, todos Git Branches por estória Repositório sempre releasable

Dia-a-dia (Sharing) Cultura de bibliotecas Plugins Gems / Gem server interno Funcionalidade compartilhada via API

Dia-a-dia (Testes) Test all the f***ing time Sem cobertura, não há conhecimento Socialização de conhecimento Integração contínua

Continuous Integration Dedicated integration environment with automated integration and tests execution with the most up to dated code base. Automated Reporting Test Cases Results Tests Coverage

Tests, tests & more tests

Continuous Integration
