Amazon EC2 Linux AMIs
If you use Amazon Elastic Compute Cloud (EC2), you are always given choices of AMIs (by default; there are plenty of other AMIs available for your base-os): Amazon Linux AMI, Red Hat Enterprise Linux, SUSE Enterprise Server and Ubuntu. In terms of cost, the Amazon Linux AMI is the cheapest, followed by SUSE then RHEL.
I use EC2 a lot for testing, and recently had to pay a “RHEL tax” as I needed to run a RHEL environment. For most uses I’m sure you can be satisfied by the Amazon Linux AMI. The last numbers suggest Amazon Linux is #2 in terms of usage on EC2.
Anyway, recently Amazon Linux AMI came out with the 2014.03 release (see release notes). You can install MySQL 5.1.73 or MySQL 5.5.36 (the latter makes the most sense today) easily without additional repositories.
The most interesting part of the release notes though? When the 2014.09 release comes out, it would mark 3 years since they’ve gone GA with the Amazon Linux AMI. They are likely to remove MySQL 5.1 (its old and deprecated upstream). And:
We are considering switching from MySQL to MariaDB.
This should be interesting going forward. MariaDB in the EC2 AMI would be a welcome addition naturally. I do wonder if the choice will be offered in RDS too. I will be watching the forums closely
