My immediate problem is that my software is running on a dedicated server hosted on-site; I have Internet access, but everything is hosted and run on a single massive VMWare ESXi server. I don't have the benefit of cloud-based services like RDS. I could modify my architecture to utilize that instead, and that's something I've thought about doing. As it stands, the VM server is UPS-backed, but does not run on SSDs. There is no SAN. If I were to fix the existing implementation, I would: a) Add a secondary VM server as a redundant backup. b) Add a SAN However, I don't think I can justify the capital expenditures for that. So what I'll likely do is replace the NFS server with a dedicated PostgreSQL server (VM), and perhaps start thinking about moving the majority of the infrastructure out of the building and into the cloud to take advantage of things like RDS. The latter is even more important for scalability as we add more customers.
