I'm actually curious about this - what makes AWS so special in terms of running VMs ? They provide something akin to VMWare's Fault Tolerance on all instances ?
Otherwise, if the host goes down, so does your vm. Scott On Wednesday, 09/04/2025 at 16:54 L. Mark Stone via mailop wrote: Sorry Michael and Scott that I wasn't clearer, and thanks for your replies. The Zimbra email software we use requires Linux instances, either Ubuntu 22, RHEL9 or selected clones. No docker containers, microservices etc. AWS has a lot of built-in infrastructure redundancy and resiliency we'd ideally like to retain (S3 has eleven nines of durability for example; EBS volumes are continuously replicated on at least two storage frames at all times, etc.). We are not at all looking for an emailing service like AWS's SES, or to use a forwarder, SEG or similar. We need like AWS m7i and r7i instances, with multiple block storage disks of different speeds and sizes, and, ideally some lower cost S3-like storage for older mail blobs. Some hosters do not allow outbound TCP port 25; that would be a requirement in our case. Thanks, Mark -- _________________________________________________________________ L.
