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.
