Testing Microservices When the Stakes Are High

Imagine a financial system that's responsible for transacting thousands of dollars per second, where a 30-second downtime means significant transaction loss not only to us but to our merchants. The key players are performance, reliability and security. Now imagine that network distributed across multiple independent artifacts, where each artifact consists of its own Virtual Machine, database schema and application.

Next imagine rolling this out on a fortnightly basis.

How would you test this? What are the challenges you might face?

The term "Microservice Architecture" has sprung up over the last few years to describe a particular way of designing software applications as suites of independently deployable services. In this masterclass, we’ll look at what microservices are, the traditional ways that people talk of testing microservices and how we do it differently.
