Critique my planned CDN/EDGE layout on buyVM
I managed to snag the third buyVM 1024 slice so now I have one in each location, and can enable anycast. Here is the plan in shitty diagram mode. I have a few questions.
- Should I roll a DNS server (I dont think I am at all qualified to do that) or should I use a RageDNS/Route53/Other Off the shelf option? If other, please post suggestions.
- Can I have a healthcheck/corosync heartbeat/other to signal the Nginx/Rproxy nodes if a backend app node goes offline?
- Should I consider using the anycast IP on the nginx/rproxy nodes?
Anything I should consider that I am not here?
