Cloud Computing - E eu com isso?

  1. 1. Cloud Computing e eu com isso? Fabio Kung
  2. 2. Cloud?
  3. 3. “The computer industry is the only industry that is more fashion-driven than women's fashion. Cloud Computing. I remember I was reading W and I read that orange is the new pink. And cloud is the new SaaS. (Software as a Service) Or cloud is the new virtualization. It is the most nonsensical. I mean I read these articles… I have no idea what anybody is talking about. I mean it is really just complete gibberish.” -- Larry Ellison, setembro de 2008 Oracle, Bea, Sun, MySQL
  4. 4. “Esse Cloud me cheira a SOA!” -- Paulo Silveira
  5. 5. “The cloud is a vague term with definitions aplenty, but what’s clear is that there is no one cloud. SaaS (e.g., Salesforce, Google docs) to PaaS (e.g., Google AppEngine or Rackspace Cloud Sites) to IaaS (e.g., Amazon EC2, Rackspace Cloud Servers) are each a category in their own right.” -- Guy Rosen
  6. 6. IaaS => Sysadmins PaaS => Desenvolvedores SaaS => Usuários
