Totally fair comparison by the way. Call out figures with from Google and
Facebook, companies with huge development budgets and data centers, teams
with tends or hundreds of developers building in house software, then
compare those deployments to a deployment of Cassandra or Riak at
Yammer.....

Random thought: Compare the availability of amazon S3, build to leverage
eventual consistency, on top of other systems with eventual consistency,
and compare that with say google cloud storage...

https://cloud.google.com/products/storage/
AvailableAll storage classes offer very high availability. Your data is
accessible when you need it. Multi-Regional offers 99.95% and Regional
storage offers 99.9% monthly availability in their Service Level Agreement.
Nearline and Coldline storage offer 99% monthly availability.

What happened to those 5 9s?
