This document outlines Ashley Davis's presentation on microservices with Node.js. The presentation will be a three-part series on building, developing, and deploying microservices. Part 1 will cover building a basic microservice with Node.js. Key topics include what microservices and monoliths are, benefits of microservices like scalability and fault isolation, and Node.js being well-suited for microservices due to its network orientation. The basic needs of a microservice like communication and storage will also be discussed.

6. What is a monolith?
A monolith is an entire application
that runs in a single process

7. What's wrong with the monolith?
•Start simple, but will become very complex
•Difficult to scale
•Difficult to restructure
•Large deployment risk
•Large attack surface
•Once dependent, it is difficult to leave
