@CodingDoug serverless / JavaScript / node.js 

@CodingDoug Cloud Functions is a Google Cloud product 

@CodingDoug Firebase adds tools and APIs 

@CodingDoug What is “serverless”? ● Servers (!!) ● No maintenance ● Automatic scaling up and down ● Pay only for what you use ● Event-driven 

@CodingDoug Cloud Functions is event-driven Cloud Functions event providers Cloud Storage Firebase Auth Crashlytics Cloud Firestore function (event) { doStuff(event) } trigger emit events 

@CodingDoug Cloud Functions scales up and down with load Cloud Functions function (event) { doStuff(event) } 

@CodingDoug Cloud Firestore Firebase Crashlytics Firebase Authentication Firebase Realtime Database HTTPS endpoints Cloud Pub/Sub Cloud Storage Google Analytics for Firebase Event providers 

@CodingDoug Why use Cloud Functions? ● Don’t repeat yourself. ○ Share common app logic between app platforms. ● Be fast and reliable. ○ Offload work to be done in the background. ● Don’t trust the user’s device. ○ Secure your sensitive code. 

@CodingDoug When NOT to use Cloud Functions? ● Your app can’t tolerate “cold start” times. ○ Instead, maintain your own servers 24/7. ● You have heavyweight work to do ( > 9 min, > 2GB mem/disk ) ○ Delegate work to App Engine or Compute Engine ● You need to keep a socket open or do streaming ○ No easy alternative
