- Bombthecat 7y agoYeah, the myth that "just use aws" to have 99, 9999999 percent uptime is coming to an end...

- dc352 7y agothat would be pretty cool but to have that, you need a high-network-latency solution, i.e., pretty much cold back-up. For some time I thought it's pretty last century option but having been experimenting for some time now, it's the option with lowest impact on system performance. More importantly, it's reasonably resilient.
- stephenr 7y agoI've read your comment now about 4 times and all I have come up with is "huh?" Literally thousands if not millions of organisations operate multi-DC infrastructure across the planet. Is it harder than setting up a single box in one DC? Yes. Is it harder than setting up a mini-cluster of boxes in one DC? Yes. Is it rocket science? No.
