  55. 55. O que críticos dizem• Operações ainda existem• As preocupações e atribuições são outras• SysAdmin ou DevOps irão operar em outro nível de abstração
  56. 56. Semântica...
  57. 57. Bottom line• Operações ficando mais baratas e simples• Desenvolvedores e empresas tendo mais foco na aplicação
  58. 58. Cada empresa tem seu nível de adoção• Cloud pode não ser pra todos• Assim como PaaS• ClickJogos gastaria na casa de milhões com tráfego na Amazon se não estivesse no UOL• Bancos jamais abrirão mão do controle
