When you build a great product it will eventually attract more and more users who will expect performance and availability. As the app grows and over time it handles more requests per minute.

So you’ve decided to learn Ruby? Great to hear! It’s always a pleasure to introduce another person into the Ruby community.

How can you avoid the headache of having multiple heavy features or services on your web app?
