What is a Serverless architecture?
How GraphQL fits into a Serverless architectureHow to get started with Serverless + GraphQL
Immediate use casesPros and Cons
Agenda
Serverless?
it’s ok to roll your eyes, no really, it is :)
Function as a Service(FaaS)
Write single-purpose stateless functions
Design push-based, event-driven pipelinesCreate thicker, more powerful front ends
Embrace third party servicesUse a compute service to execute code on demand
Principles of a Serverless Architecture
👁 ❤
Lambda is really cool, but is a massive pain to setup
Click "Create a Lambda function"Choose a Blueprint functionConfigure how it is triggered (API Gateway, DynamoDB, CloudWatch, etc.)Configure the function
Runtime (Node.js 4.3)MemoryTimeoutLambda function code (in WYSIWYG editor)Handler path inside containerRole creationPolicy creationVPC access
"Optimize human time, not machine time"

Automation for working with AWS Lambda, etc.

Using GraphQL + Serverless to serve up endless Dad Jokes
Pros
No longer managing servers
Not running server(s) 24 / 7Scale instantly
Serverless, Apex, etc.AWS, Google, Microsoft, IBM solutions
Pay only for what you use
Marketing site (S3) + FormMobile backendsBackground Jobs (Image resize, log processing)CMS and low-bandwidth BFF's (Backend's for Frontend’s)Any pre-compute stored (S3) for later retrievalStartups / Prototyping productsTest, Dev and Staging environments
Immediate Use Cases
Server-rendered ReactSecurity/Compliant heavy appsRead-only API’sAnything with an SLAHigh throughput / availability
Possible, but not a good fit?
ConsLimited documentation/examples
Latency
Best practices are still being defined
Security
Offline development
Serverless (v0.x stable, v1 beta), Apex, etc.
Debugging whoas
Cons
