Let us start by using a small example. We will start by looking at a small database setup. This setup will have a single master-slave, with a database size of lets say 500GB. Traffic is steady and let’s say this translates into 500 IOPS on the master. You have chosen …

Join 29,000 others and follow Sean Hull on twitter @hullsean. Can RDS worsen an outage ?? That’s another way to think about this question.

Are SQL Databases Dead?

I like the image of this city of Mesa Verde. It’s fascinating to see how ancient cities were built, especially as an inhabitant of one of the worlds largest cities today, New York. I’m a long time relational database guy. I worked at scores of dot-coms in the 90′s as an old-guard Oracle DBA, and […]
