Serious question: Do modern "all in the cloud" tech companies actually have DR plans?
All the presentations i've seen about people deploying in the cloud leaves out any DR site, replication process, turnover time for the DR site taking production traffic, etc. It's like they believe redundant machines will save them from an admin accidentally hosing their prod site and having to take 3+ days to recover.
- poooogles 11y agoWe backup from GCP to S3, pretty much everything else is in a git repo that we can redeploy from. Would be a right pain but definitely not 3 days.
- peterwwillis 11y agoThat's not a DR plan...
- twunde 11y agoIt really depends on the company. My suspicion is that companies only get serious about DR once they reach a fairly big size. When I interviewed at Squarespace they were just finishing building out their second datacenter. At that point it was a DR data center but they were planning on switching all production traffic to it in the coming months. Most of the startups/midsize companies have relied on a third-party for backups ie Rackspace.
- peterwwillis 11y agoThat's what strikes me as odd. Even small and mid-size companies can do this for cheap if they're mostly cloud-based. Stand up the environment at another cloud provider, keep resource use at 1% that of your current provider, implement a continuous replication procedure, document the failover procedure, and test-run once a month. Much less work than actually buying and organizing some small colo space in another DC, and way faster than scrambling to recover. Yet I don't know of a single cloud-dependent company that does this unless it's for performance reasons.
