Amazon RDS for MariaDB Finally! I have been broadcasting for sometime that the reason that Amazon has not moved RDS MySQL from it’s 5.6.x version, was due to the belief that Oracle was intending to charge an arm-and-a-leg from AWS for the privilege of doing the upgrade to 5.7.x. I was of the opinion that this was the initial reason for AWS Aurora, to have an alternative both to arm twist Oracle into a better deal for MySQL 5.7, but also a fallback position should Oracle refuse to bargain.
Now that whole subject has been rendered null and void with this announcement. The MySQL community will now have a direct replacement, with improvements, from the 5.6.x installations into MariaDB 10.x and the Oracle (toll booth) issue can now be side stepped entirely.
I have already indicated to my management that this move should be undertaken as soon as is viable.
I’m testing Aurora, and now I can’t talk about it. But I believe I understand why its named Aurora.
Being a user of MySQL (5.6) on the Amazon RDS I was impressed with the announcement of Aurora. Having said that I was also suspicious as to it’s providence. Nowhere were there references to it’s origins or engines. Databases and database systems don’t just drop out of the sky.
Amazon were also was making comparisons to MySQL version 5.6, not the newest version 5.7.x. This is interesting as I have been fighting I/O issues in the RDS implementations of MySQL 5.6.x for sometime. Version 5.6 has serious Mutex issues in I/O and from my reading MySQL 5.7 has managed to improve that situation. But the Amazon folks have not managed that upgrade yet.
Software politics being what it is, especially with regards to Oracle, whom own MySQL, indicates that there will be licensing issues with the release of MySQL 5.7.x. Issues that Amazon may be seeking to side step or ameliorate with the threat of Aurora (or MariaDB).
Having said that, many of the DB community seem to be of the opinion that Aurora does not offer anything that can’t be found within the MySQL 5.7 upgrade, as far as performance is concerned.
What does concern me is the lack of transparency about the nature of Aurora. What I see is smoke and mirrors. And frankly in the DB community, that does not lend trust to the Aurora project of Amazon’s. Not a good thing where trust, and dependability are Keys. (pun intended)
Well, I’ve worked myself out of another job, mostly, as I assisted the current company into the Amazon cloud. They were operating their system from a hosting environment, so they were mostly in the ‘Cloud’ anyway. And as you might guess I dislike the whole ‘Cloud’ hype as it’s mostly a marketing term. So what I convinced them to do, is improve their scalability by moving the server into the equivalent systems in the Amazon ‘hosting’ environment.
As part of the exercise the database from move from a MySQL database on Windows server, to the Amazon RDS the the webserver/application servers (windows) to EC2 instances, with additional storage in the Amazon S3 facility.
The process was, as usual, a learning experience, and Amazon still has issues with their interfaces to their corner of the Cloud. But it all works, I managed to defrag the database, and apply more indexing and SQL revisions to the point that it runs so smoothly, they don’t need me anymore. Hence the working myself out of a job. Amazon should hire me to sell their services.
It is with sadness that I had to turn off the last Sybase Instance we had running. Our last ASE server quietly shutdown on an Amazon EC2 server on Tuesday the 20th of December, never to boot again.
In all truth both Sybase instances were developer installs operating as production systems. Our two instances, operating with the 25 user limit that each was restricted to, was barely able to operate the system. But the Sybase Licensing was too archaic and inflexible to continue operating it as a small business. Thus the economics forced us to convert to MySQL.
If it hadn’t been for the previous management, who in some delusion of saving money, refused to pay the datacenter bill, forcing us to move the Sybase instances out into the Amazon cloud (EC2) in the first place we would probably have been on MySQL sooner, as that was the plan.
But the sadness remains, Sybase as a technology proved again that it would run, and run reliably, on just about any hardware, even when it was virtual, and NOT meeting the specified certified, requirements of operation. Which can’t be said for the Amazon RDS version of MySQL, which crashed spontaneously while applying an index on our live production database without warning. This having happened after weeks of testing and trial runs at operating the system on it. The only defense, the RDS instance rebooted and was available without data loss, in less time than a Sybase HA switchover would have taken, a system this production system was developed from.
So we are up in MySQL and I am now a MySQL DBA exclusively, after spending the last 25 years as a Sybase DBA and evangelist. The decision now has to be rather to remain so, or find another place of employment where Sybase remains. Those are becoming more and more rare. Maybe I should takeup MongoDB to stay at the cutting edge.
