For AWS we rely almost entirely on backup/restore and database level log shipping on prem this is is in some cases argumented by storage level(netapp and previously hpe 3par) replication but this is going away for cost reasons. Given that my experience with AWS is to use the same application level cross region resilience techniques im used to on prem(i have worked with high end unix boxen most of my carear) im genuinely baffled when people start talking about cloud resilience as something magical, and nearly all our traffic happens inside of an private network(MPLS/VPN) that stretches across the different sites. I really haven't seen any magic multi-az resiliiance in aws that dont have an onprem counter part. None of this is in house whitebox hardware but relatively standard solutions from established vendors(VMware recently started abusing their near monopoly so everyone is looking for/at alternatives like proxmox, xen and nutanix but arent ready to move just yet).
