Visão Geral

Curso Introduction to Building And Deploying Openstack Cloud Systems. OpenStack é uma estrutura de computação em nuvem de código aberto amplamente utilizada. Desenvolvido originalmente em conjunto com a NASA e a Rackspace, agora é uma parte importante dos produtos de serviços web da Rackspace. A Rackspace está ativamente envolvida no desenvolvimento do OpenStack e versões mais recentes estão sendo lançadas em intervalos regulares. A versão mais atual é o Grizzly, e seu sucessor, Havana, está em processo de desenvolvimento e testes. O Openstack é adequado para pequenas empresas e também está sendo usado por algumas grandes corporações. RedHat, Dell e HP também apoiam ativamente a iniciativa Openstack. Tal como acontece com muitas estruturas de código aberto grandes e complexas, existem várias “ramificações comerciais” que fornecem suporte técnico e produtos complementares. Este curso se concentra nos elementos de código aberto do Openstack e é independente de qualquer organização específica que forneça produtos comerciais baseados em openstack.

Pre-Requisitos

• Conhecimento básico de Linux, ferramentas e utilitários de linha de comando Linux, redes Linux e TCP/IP e programação shell. Alguma experiência prática em administração de sistemas seria vantajosa. 
• Este Curso Introduction to Building And Deploying Openstack Cloud Systems é destinado a administradores técnicos de sistemas, gerentes técnicos de TI e data centers e planejadores estratégicos.
