Instapaper Outage Cause & Recovery
Hard to see this as anything other than a pretty awful documentation fail by the AWS RDS service:
Without knowledge of the pre-April 2014 file size limit, it was difficult to foresee and prevent this issue. As far as we can tell, there’s no information in the RDS console in the form of monitoring, alerts or logging that would have let us know we were approaching the 2TB file size limit, or that we were subject to it in the first place. Even now, there’s nothing to indicate that our hosted database has a critical issue.

AWS Case Study: mytaxi
ECS, Docker, ELB, SQS, SNS, RDS, VPC, and spot instances. Pretty canonical setup these days...
The mytaxi app is also now able to predict daily and weekly spikes. In addition, it has gained the elasticity required to meet demand during special events. Herzberg describes a typical situation on New Year's Eve: “Shortly before midnight everyone needs a taxi to get to parties, and after midnight people want to go home. In past years we couldn't keep up with the demand this generated, which was around three and a half times as high as normal. In November 2015 we moved our Docker container architecture to Amazon ECS, and for the first time ever in December we were able to celebrate a new year in which our system could handle the huge number of requests without any crashes or interruptions—an accomplishment that we were extremely proud of. We had faced the biggest night on the calendar without any downtime.”

5 subtle ways you're using MySQL as a queue, and why it'll bite you
Excellent post from Percona. I particularly like that they don't just say "don't use MySQL" -- they give good advice on how it can be made work: 1) avoid polling; 2) avoid locking; and 3) avoid storing your queue in the same table as other data.
