3. Overview
– Traditional vs Serverless Applications
– Twitter Bots
– Generative Art
– Serverless (AWS Lambda)
– Monitoring a Serverless Application

4. What is Serverless?

5. Traditional Architecture
– LAMP, MAMP, MEAN, JAM
– 100% Uptime
– Full Control over Software Versioning
– Usually Monoliths

6. Microservice Architecture
– Can run across multiple stacks
– Separate Deploys
– Modular

7. Serverless
– Cloud provider executes code
– Don’t have to think about servers at all
– Pay only for what you use
– Easier to adapt to demand at scale

8. AWS Lambda
– Zero Administration
– Automatically allocates compute execution power
– Set code to automatically trigger
– Write in your favorite programming language
