Resumo
O trabalho apresenta os conceitos de Cloud Computing e virtualização relacionando-os com o fornecimento de recursos de infraestrutura computacionais sobre demanda. Demonstrando para os usuários o modo como são providos recursos computacionais através de uma plataforma de Cloud Computing. Descreve as plataformas mais utilizadas no mercado e a plataforma de Cloud Computing da IBM que faz uso da arquitetura mainframe. Apresentando os benefícios em termos de escalabilidade, flexibilidade, segurança e economia obtidos com a utilização de Cloud Computing. Apresentando a relação entre mainframe e Cloud Computing, de modo que essa combinação possa ser considerada uma das melhores plataformas provedora de recursos computacionais sobre demanda. Proporcionado a utilização de ambientes com todas as características (segurança, disponibilidade, estabilidade e escalabilidade) que o mainframe já esta acostumado a prover. E por fim afirmando que o fornecimento de recursos computacionais sobre demanda possui muitos benefícios e cada vez mais será adotada pelas empresas e usuários. Sendo que o mais importando sobre Cloud é que ela foca-se no modo como são providos e utilizados os recursos computacionais, e não em onde eles estão alocados. Provendo liberdade aos usuários de modo que esses possam inovar em suas soluções sem ter que preocupar-se com a infraestrutura computacional
The current computing model is becoming hardier to support. Almost every time when you need more computing resources (processor, memory or hard-disk) you have to change the entire computer, because you cannot change just one component. Those components become outdated in a fast way (normally 6 months or 1 year). In most of the cases the users (end users and companies) are forced to buy hardware that they do not need most of the time, because they cannot upgrade the computer capacity on the fly. The best way to do computing is having the required resources at the right time and place. As an example, I do not need 200GB of hard-disk to save my files, today I may need 100GB, tomorrow 150 GB and later 200GB. In the future if I do not need 200GB, I could decrease the storage capacity to 150GB or 100 GB, it also could be done with processors and memory. Using just the resources needed, means spending less, managing and maintaining resources that are not totally used. Using on demand computing, the users do not care about hardware and software management and maintenance. Avoiding the hardware and basic software such as operational systems and default apps management the users and companies can focus on innovation. Cloud computing enables users to have the needed resources everywhere and every time through a simple device, because of that the resources are provided by Internet or corporate networks. Today there are technologies that can provide on demand computers resources, in secure, reliable, and cost effective ways. Users should have in their minds that cloud computing is a new computing paradigm, delivering on demand computer resources through networks. And the Mainframe came to this scenario as one of the best platforms to apply the cloud computing concepts building a secure, reliable and cost effective cloud. The Mainframe architecture fits perfectly to support the cloud needs
