O que ESB e SOA são, afinal? | |
============================ | |
A sigla ESB, e outra relacionada - SOA - podem ser uma fonte de confusão. ESB se expande para Enterprise Service Bus. SOA significa Arquitetura Orientada a Serviços. | |
Isso ainda não explica muito por isso damos aqui mais informações em linguagem simples, sem demasiado jargão corporativo. | |

BALADA - A MAIOR MENTIRA DA TERRA | |

Entradas para as mulheres são sempre cortesias. Os homens pagam caro. E não se enganem achando que as mulheres não pagam a entrada, quem paga são os homens.
