During the past eight months we’ve deployed a number of single- and multi-server Zimbra systems on Amazon Web Services (“AWS”).  While Zimbra has a number of Deployment Guides, they are generic by nature and do not describe how to leverage AWS features to maximize cost savings, reliability, performance and security.  At this writing, Zimbra has no Reference Architectures for AWS hosting, let alone choices for aggressive RPO/RTO targets (at higher costs) vs. more modest RPO/RTO targets.

Further, our experience has been that even seasoned Zimbra system administrators can find the transition to hosting on AWS somewhat challenging, too often resulting in suboptimal architecture choices that increase costs, reduce performance, reliability etc.

Consequently, based on the multiple Zimbra installations we’ve performed on AWS to date, we’ve created a PowerPoint covering Zimbra Hosting on AWS – Best Practices From The Field.
