In Rails, we're more likely to use SQL databases than other frameworks. Unlike NoSQL databases, which can be scaled horizontally with relative ease, SQL databases like PostgreSQL or MySQL are much less amenable to easy scaling. As a result, our database usually becomes the primary bottleneck as our business grows. Although SQL databases are very efficient, as our growing customer base puts an increasing load on our servers, we begin scaling our instance counts, workers, etc.

We're excited to share that AppSignal has once again been recognized as one of the top performance and error monitoring tools in the 2024 Ruby on Rails Community Survey.
