Agenda & takeaways
● Introduction● Platforms● Inspiration● Summary
● What● How● Why● When
01IntroductionWhy are you here?
Serverless computing means opinionated logic-hosting containers in
the cloud.
Serverless: the what● Misnomer● "No worries"● According to Forbes*:
○ Developers focus on writing code & solving business problems without having to worry about infrastructure.
○ Servers (physical & virtual) completely abstracted away from the user.
* source: Forbes (May 2018)
Serverless: the why
● Fastest growing segment of cloud*
● $1.9B (2016) and $4.25B (2018) ⇒ $7.7B (2021) and $14.93B (2023)
● What if you go viral?● What if you don't?

02PlatformsGCP + G Suite
Google App EngineApp-hosting in the cloud
Why does App Engine exist?
App Engine to the rescue!!
● Focus on app not DevOps● Enhance productivity● Deploy globally● Fully-managed● Auto-scaling● Pay-per-use● Familiar standard runtimes
Hello World (3 files: Python "MVP")app.yaml
runtime: python37
main.py
from flask import Flaskapp = Flask(__name__)
@app.route('/')def hello(): return 'Hello World!'
requirements.txt
Flask==1.0.2
Deploy:$ gcloud app deploy
Access globally:https://PROJECT_ID.appspot.com
Popular App Engine use-cases
● Mobile/tablet○ App backends○ Cloud persistence
● Social/gaming○ Speed, scale○ API integrations○ Personals/dating
● Consumer web apps○ Unpredictable traffic○ Scale (up or down)
● Business apps○ Enterprise○ Java & PHP runtimes○ Web or mobile
Google Cloud FunctionsFunction-hosting in the cloud
Why does Cloud Functions exist?● Don't have full app
○ No framework "overhead" (LAMP, MEAN...)○ Microservices
● Event-driven○ Triggered via HTTP or background events○ Auto-scaling & highly-available○ Pay per use
● Familiar development environment○ Cmd-line or developer console
● Cloud Functions for Firebase
main.py
def hello_world(request):
return 'Hello World!'
Deploy:$ gcloud functions deploy hello --runtime python37 --trigger-http
Access globally:https://GCP_REGION-PROJECT_ID.cloudfunctions.net/hello
Hello World (Python "MVP")
Google Apps ScriptCustomized JS runtime for automation, extension, and integration with G Suite and other Google or external services
Sheets-bound “Hello World!”
Apps Script introgoo.gl/1sXeuD
Sheets-bound “Hello World!”
What can you do with this?
Accessing maps from spreadsheets?!?goo.gl/oAzBN9
This… with help from Google Maps & Gmailfunction sendMap() { var sheet = SpreadsheetApp.getActiveSheet(); var address = sheet.getRange("A2").getValue(); var map = Maps.newStaticMap().addMarker(address); GmailApp.sendEmail('[email protected]', 'Map', 'See below.', {attachments:[map]});}
JS
Google App MakerLow-code assistive development for custom business apps
Got app licenses for sales, marketing & operations?
BUT...
Who builds my app? If no resources, how do I do it myself?
Custom business apps: still no easy solutions
Who will pay for it?
What platform should I use?
Where do I host my data?
Is my app compliant?
Who has access to my app?
● Low-code assistive development environment; Cloud SQL default
● Go from idea to app in minutes ● Drag-n-drop app building● Many pre-made template apps● Generates Apps Script code● Requires at least G Suite Business

Google Cloud RunContainer-hosting in the cloud
The rise of containers ● Any language
● Any library
● Any binary
● Ecosystem of base images
● Industry standard
“We can’t be locked in.”
“How can we use existing binaries?”
“Why do I have to choose between containers and serverless?”
“Can you support language _______ ?”
Serverless not accessible to everyone...
● Fully-managed serverless "CaaS"○ Flexibility and portability of containers, but
with the convenience of serverless○ You app, your bundled container○ Auto-scale, -provision, -config○ Pay-per-use
● Anti-vendor lock-in, portable to:○ Google-managed Kubernetes cluster (GKE)○ Or your self-managed Kubernetes cluster
Google Cloud Run to the rescue!
Code, build, deploy.js .rb .go
.sh.py ...
● Any language, library, binary
○ HTTP port, stateless
● Bundle into container
○ Build w/Docker or
○ Google Cloud Build
○ From Container Registry...
● Deploy to Cloud Run
