Again, a partition that leaves you with no quorum anywhere is like the cloud being down.

- pessimizer 2y agoA partition that leaves you with no quorum anywhere is like the cloud being down if you value consistency over availability.
- cryptonector 2y agoYes, but again, TFA says that you will trust the cloud will be up long enough that you would indeed prefer consistency. My goodness. So many commenters here today are completely ignoring TFA and giving lessons on CAP -- lessons that are correct, but which completely ignore that TFA is really arguing that clouds move the needle hard in one direction when considering the CAP trade-offs, to the point that "the CAP theorem is irrelevant for cloud systems" (which was this post's original title, though not TFA's).
- pyrale 2y agoThe issue people are pointing is that the author conflates "Cloud is good enough for my needs" with "CAP is no longer relevant".The point is especially annoying considering that the author works at a cloud vendor and not a cloud user.
- robertlagrant 2y ago> Again, a partition that leaves you with no quorum anywhere is like the cloud being down. What does this mean? What is the cloud being down? The cloud isn't a single thing; it's lots of computers in lots of data centres.
- NavinF 2y agoIt means there will be an article on the front page declaring the outage
- Spivak 2y agoHuh? You can create partitions in ways other than issues with the underlying network. You can mess up firewall rules for example and find yourself with no quorum.
