Public clouds will have outages - that's not the point. What's most concerning about this outage is that it is across all regions. That violates the fundamental assumption, of developing for the cloud, that failures in every region are independent.
If regions fail independently and a failure in 1-2 regions brought down my system, that's my fault. But if region failures aren't independent and a global outage such as this is possible - well, that's pretty bad.
- cheeze 7y agoYup, fully agreed. Nobody can keep sql instances or hosts up forever. They will go down. Further, humans work on this stuff. Humans make mistakes. Bad config push, bad code push, lightning hitting a data center, human vandalism, etc. will happen. What shouldn't happen ever is that your entire cloud goes down because somebody pushed a bad config change to a service that serves literally your entire cloud. Microsoft clearly hasn't architected everything to be region-independent. There are things that will always be somewhat global, but Azure seems pretty bad at this. This isn't the first time even in the past 12 months that they've had a global outage.
