Os novos caminhos da virtualização
A cada dia que passa, mais temos visto os antigos ambientes complexos e custosos serem resumidos a um grande sistema virtual. Ambientes antes limitados a hardware físico tem sofrido o boom da virtualização. O que era incomum, agora se tornou rotineiro. O que antes era impossível, hoje faz parte do nosso dia a dia.VVR - Bunker Replication
Dando continuidade a questão replicação disponíveis para o cliente, podemos recomendar o melhor dos dois mundos. Como tratado anteriormente, ao se deparar com as dúvidas de disponibilidade e ponto de recuperação em um ambiente de DR, existem duas maneiras de se trabalhar com essas variáveis, replicação síncrona e assíncrona.
