This document outlines the agenda and content for a Cloud-Native Roadshow presentation on microservices and Feedback Bot. The presentation covers microservices concepts like architecture, benefits of microservices at scale, and responsible design. It then introduces Feedback Bot and its architecture. The presentation discusses how Feedback Bot consumes external Google Machine Learning services and how services are managed in Pivotal Ops Manager. Finally, it covers how Feedback Bot is designed to handle failures gracefully.

Microservices | What are they?
Loosely coupled service oriented
architecture with bounded contexts
Adrian Cockroft
If every service has to be updated in concert,
it’s not loosely coupled!
If you have to know about surrounding services,
you don’t have a bounded context.

Kenny Bastani on Microservices
“A microservice is an application small enough
that an engineer new to the source code can
reason about it in a day or less.”

7. pivotal.io/roadshow #cnr
Microservices | Why are we all trying to do this anyway?
Organizational Scale
Increased Agility
Increased Development Velocity
Cost efficient scaling
Faster onboarding
Attract more talented engineers
Fault Isolation
