SCALE 13x and “Yes, you still need a DBA”

by gorthx

Last weekend, I got to give a talk at SCALE‘s LA PgDay for the second year in a row. PGDay was two days this year, and unfortunately I had to miss Thursday – looks like I missed some great talks, too, dangit!

I reprised my RDS talk from PDXPUG’s January meeting. It certainly sparked some interesting discussions later.

(If you are too shy to ask questions in my talk, it is totally ok to come up afterwards and ask them, or stop by the Postgres booth & talk to me. That’s what I’m there for!)

I mentioned something in my talk that I want to throw out here because it’s been coming up in conversations recently:

If you have production data that you want to protect, you need a database adminstrator. Even if you are using a managed database service (RDS, Heroku, what have you), you need someone to:

– Choose an appropriate instance size for your workload
– Configure Postgres appropriately (as much as is possible on a managed service, anyway)
– Secure and audit databases
– Ensure data quality
– Tune queries (e.g. figure out what in [Sam Hill] the ORM is doing)
– Mentor devs
– …add your own here…

None of these tasks go away just because you’re using a managed database solution. You still need someone who can hop in there & get her hands dirty. You may disagree, but please keep this list handy http://www.postgresql.org/support/professional_support/.
