Serverless HTTP applications Sourced-based web apps App Engine Serverless functions and events Source-based event driven functions Cloud Functions Serverless HTTP containers Fully managed HTTP req/res containers HTTP req/res containers on GKE Cloud Run Google Cloud Compute Serverless Options

Cloud Functions

Cloud Functions as a cloud glue Access 20+ Google services from GCF Cloud Storage Cloud Pub/Sub HTTPS Firebase Cloud Scheduler Cloud Tasks

Cloud Functions runtimes NEW!

HTTP functions Cloud Functions provides a URL for your function Invoked by an HTTP call GET, POST, PUT, DELETE, OPTIONS Function replies with HTTP response Header, body, status code, etc. Background functions React to events in your cloud infrastructure Pub/Sub message on a topic New file on Cloud Storage Change in Cloud Firestore docs Audit log event Two Types of Functions

DEMO Micronaut HTTP & Background Functions

App Engine

Serverless, but for your whole web app and not just single functions Goal: let developers focus on code, GCP handle the rest Open-source, idiomatic experience Use any library, extension, binary, or framework Java, Python, Node.js, PHP, Ruby, Go What’s App Engine?

Scale up / down quickly One vs. multiple concurrent requests Traffic splitting across versions (A/B testing, Canary or Blue/Green depl.) CDN static asset serving Concurrency & Scaling Traffic Traffic

Cloud Run

Any language Any library Any binary Ecosystem of base images Cloud Run .js .rb .go .py .java … 0 1 0 1 0 0 1 1 1

Cloud Run Cloud Run Fully managed, deploy your workloads and don’t see the cluster. Cloud Run on Anthos Deploy into Anthos, run serverless side-by-side with your existing workloads. Knative Everywhere Use the same APIs and tooling anywhere you run Kubernetes with Knative.

Listen on 0.0.0.0 on port $PORT (default 8080) HTTP server must start < 4 min (timeout → 504) Request time < 15 min (default → 5 min) Stateless (in-memory file system, doesn’t persist) Computation only within request (no background activity) Container Contract

Pay Per Use CPU / Memory / Requests 100ms

Billable Time Instance Billable Time Request 1 Start Request 1 End Request 2 Start Request 2 End Instance Time Billable Non-billable

Summary

Google Cloud allows you to run your Micronaut functions, apps, and containers on: ● App Engine ● Cloud Functions ● Cloud Run Take advantage of the various data storage, communication channels, machine learning options… Why Micronaut? Because it starts fast and consumes less memory than the competition! Run Micronaut Serverlessly!
