Not enforcing SSL on CloudSQL, really !

When creating a MySQL CloudSQL instance, SSL connections are not enforced by default and you get below in the Connections tab of the Google Cloud Platform console.  Is this a problem ?  Some people might think no, but I do not agree with them.  And if I am writing this post, you can probably guess that there is a lot to say about this subject.  Read on for the details.

Unforeseen use case of my GTID work: replicating from AWS Aurora to Google CloudSQL

A colleague brought an article to my attention.  I did not see it on Planet MySQL where I get most of the MySQL news (or it did not catch my eye there).  As it is interesting replication stuff, I think it is important to bring it to the attention of the MySQL Community, so I am writing this short post.
