Scalæ By the Bay

Colossus is a Scala I/O and microservice framework that has been built from the ground up with a strong focus on performance and simplicity. While primarily aimed at building low-latency services, it can serve as a fully generalized I/O layer for virtually any application. Whether you're doing low-level bit-pushing or making high-level distributed services, Colossus is here to help. In this talk I'll cover the basics of what Colossus can do, how we made it fast, and how we use it at Tumblr to power some of our platform's most popular features.
