The bumpy road towards containerised microservices: why early adoption meant it took longer for us to get there

A more up to date version of my "Journey to containerised microservices". I did this talk at Cloud Native London 2018 and JAXLondon 2018:

How we run our applications is always evolving – Monoliths to microservices, migration to the cloud, containerisation, improved orchestration. Containers have become synonymous with microservices but they present a new set of challenges…

In this talk I will share some of our experiences and rationale behind early adoption of containerisation using an in-house written orchestration mechanism through to migrating to Kubernetes.

In this talk I will discuss:

Our motivation for moving services into containers
The pain that went along with very early adoption
Which development approaches and practices help or hinder containerising a service
How our development process changed when we started running in containers
Best practices and lessons learnt around migrations
