What are Microservices?
Microservices is an architectural style that structures an application as
a collection of loosely coupled services

Event bus
Event bus allows publish-subscribe-style communication between components without requiring the
components to explicitly register with one another
Microservice principles • Lightweight protocol between services • Small services,
one job per service • Service independence • Easier to understand, develop and test • Speeds up development • Enables continues delivery and deployment
Why Node.js? • Small and lightweight! • No boilerplate code
• Non-blocking I/O • Speed! • Freedom
None
Tools • Docker - containers • Kubernetes - container orchestration
• Kafka - messaging • Elastic Stack - logging
None
Docker is a tool designed to make it easier to
create, deploy, and run applications using containers
Containers allow developer to package up an application with all
of the parts it needs, such as libraries and other dependencies, and ship it all out as one package
