Cloud Computing
    e eu com isso?



     Fabio Kung
Cloud?
“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
“Esse Cloud me cheira a SOA!”
                       -- Paulo Silveira
“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

Cloud Computing - E eu com isso?

Editor's Notes

  1. - desperdício (energia, processamento) provisionamento rápido upgrade: escalabilidade vertical/horizontal
  2. rede (sharing, vlans) storage cloud != virtualização gerenciamento
  3. SR-IOV
  4. Sniffing
  5. DDoS Spam Jogos Brute Force
  6. faltam: Locaweb, Linode gae nao aparece porque eh plataforma, mas tinha 80 em agosto!
  7. Amazon VPC VPNCubed
  8. According to InformationWeek, "The system is priced at less than $100,000. It holds the capacity of up to 232 x86 servers within a footprint that's 83% smaller.
