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

IaaS => Sysadmins PaaS => Desenvolvedores SaaS => Usuários

Virtualização to rule them all?

Desperdício Provisionamento Capacity Planning Manutenção Disponibilidade Custo

Xen, KVM, Hyper-V, VMware

SAN? NAS? Fiber Channel?

PaaS simpliﬁca o desenvolvimento mas restringe suas opções em relação ao IaaS.

Casos... “é ver para crer”

Problemas do NYT • Liberar jornais de1851-1922 (11M artigos) • 4 tera de TIFFs • 1 ano de grande computador! http://open.blogs.nytimes.com/2007/11/01/self-service-prorated-super-computing-fun/

Solução do NYT • 100 micros EC2 • 1 dia de uso • Hadoop, IText, JAI • custo: $240

nem tudo é nuvem...

Problemas no GAE 1. Big Table (proprietario) 2. Restricoes 3. Teste 4. DocumentaCAO

Seria melhor o EC2? PaaS ou IaaS?
