Lessons learned from operating a Scala-based system for 3 years

It’s been three years since the official rollout of Mackerel, a service that my team at Hatena builds using Scala on the server-side.

Here are some of the things that happened while we operated the system for three years.

• Tracking version upgrades of frameworks and libraries that we use.
• Deprecating some of the provided features, and subsequent removal of the source code.
• Tackling technical debts.
• Expanding hardware infrastructure following the system growth.

In this session, I would like to share how we tackled these problems and the lessons learned through operating Scala-based production system Mackerel for three years.
