Banking on Thousands of Microservices

Monzo has built an entire banking platform from scratch composed of many microservices; it serves over 7 million customers daily with an organisationally lean engineering team. All aspects of the bank are deployed hundreds of times a day (even on Fridays!).

This talk will cover lessons learned from building a bank, starting from technological choices like using Cassandra and Kubernetes in the early days to how Monzo has maintained its speed of execution through platform engineering and developer experience. We will also cover some mistakes and incidents we've had along the way.
