A guided journey of Cloud Native

Presented with Cheryl Hung from CNCF at QCon London 2019

The Cloud Native Trail Map provides a path for enterprises to deploy cloud native applications, and the steps they’ll encounter along their journey. However, the needs of each enterprise are rarely the same and these journeys are rarely linear.

We examine the journey that Monzo, a UK based digital bank, have taken over the last four years, the stages they went through as they grew, the challenges they faced at each point, and the technologies and techniques they used to build a cloud native bank.
