@glaforge Not Google’s new serverless data center

@glaforge The Serverless spectrum

@glaforge Serverless operational spectrum Managed by your cloud Container orchestration (k8s) Not serverless for programming or ops Container focused Infra managed by you Hosted FaaS/compute Easiest dev experience Code focused Limited runtime options Managed by your team Serverless anywhere Knative / Cloud Run on GKE On prem or multi-cloud Code or containers Custom hardware (GPU, TPU, IoT, etc) Offline You manage infra Serverless containers Custom languages & runtimes Infra still cloud-managed

@glaforge Serverless “compute” on Cloud Platform App Engine Standard Highly scalable, serverless web applications. Deploy and scale Applications that react to Requests Cloud Functions Event-driven serverless compute platform. Deploy and scale Functions that react to Events Cloud Run Highly scalable, serverless stateless containers. Deploy and scale Containers that react to Requests

@glaforge So what did we launch?

@glaforge New idiomatic App Engine runtimes ○ Python 3.7 (GA) ○ PHP 7.3 (GA) ○ Go 1.12 (GA) ○ Node.js 10 (GA) ○ Java 8 (11 in beta) ○ Ruby 2.5 (in alpha)

@glaforge Double the memory! 2x

@glaforge App Engine Java 11 (beta) ● Executable JAR support ○ Servlet containers not required ○ Choose your favorite web framework & libs ● Custom entrypoint ○ Full control on how to start your application ○ Graal VM executables possible ● More idiomatic ○ No more class whitelist ○ Runs in a gVisor based secured sandbox

@glaforge ○ General Availability with SLA ○ Go, Node & Python ■ Java in alpha ○ Security & scaling controls ○ Environment Variables Cloud Functions

@glaforge New Go 1.11 runtime (1.12 in alpha)

@glaforge Go 1.11, vendor & module friendly package hello import ( "fmt" "net/http" ) func HelloWorld(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello, World!") } $ gcloud beta functions deploy hello --entry-point HelloWorld --runtime go111 --trigger-http

@glaforge Node 8 with async / await const PubSub = require('@google-cloud/pubsub'); exports.helloPubSub = async (data, context) => { let ps = new PubSub(); try { const topicName = context.resource.name; const topic = ps.topic(topicName); const data = await topic.getMetadata(); const metadata = data[0]; console.log(`Metadata: ${JSON.stringify(metadata)}`); } catch(err) { console.error(err); } };

@glaforge Java HTTP functions import javax.servlet.http.*; import java.io.*; public class Example { public void helloWorld(HttpServletRequest req, HttpServletResponse resp) throws IOException { PrintWriter writer = resp.getWriter(); writer.write("Hello world!"); }

@glaforge Java background functions — Pub/Sub import java.util.*; import java.util.logging.Logger; public class Example { public void helloPubSub(PubSubMessage message) throws Exception { String data = new String(Base64.getDecoder() .decode(message.data.getBytes("UTF-8"))); // do something with data } class PubSubMessage { String data; Map attributes; String messageId; String publishTime; }

@glaforge Environment variables $ gcloud beta functions deploy fnNAme --set-env-vars FOO=bar $ gcloud beta functions deploy fnNAme --env-vars-file .env.yaml --update-env-vars FOO=baz --remove-env-vars FOO --clear-env-vars

@glaforge Function scaling control Limit scaling on a per-function basis Prevents DoSing resources with different scalability $ gcloud functions deploy --max-instances=100

@glaforge Security controls Control access to function invocation using IAM ● Developers ● Other functions or GCP services ● End-users using Google Sign-In Set IAM policies on individual functions Private by default

@glaforge Security controls $ gcloud functions add-iam-policy-binding fnOne \ --member='allUsers' \ --role='roles/cloudfunctions.invoker' $ gcloud functions add-iam-policy-binding fnTwo \ --member='fnOne@projectid.iam.gserviceaccount.com' \ --role='roles/cloudfunctions.invoker'

@glaforge Per function identities By default, all functions share the same identity Identity can be set on a per-function basis to provide least privilege access

@glaforge Per function identities $ gcloud iam service-accounts create fnOne $ gcloud iam service-accounts add-iam-policy-binding \ fnOne@projectid.gserviceaccount.com \ --member='serviceAccount:fnOne@projectid.gserviceaccount.com' \ --role='roles/cloudfunctions.invoker' $ gcloud functions deploy fnOne \ --service-account fnOne@projectid.gserviceaccount.com

@glaforge Per function identities $ gcloud iam service-accounts create fnTwo $ gcloud iam service-accounts add-iam-policy-binding \ fnTwo@projectid.gserviceaccount.com \ --member='serviceAccount:fnTwo@projectid.gserviceaccount.com' \ --role='roles/cloudsql.client' $ gcloud functions deploy fnTwo \ --service-account fnTwo@projectid.gserviceaccount.com

@glaforge Cloud Run Serverless Containers

@glaforge Everything at Google runs in containers: Gmail, Web Search, Maps, ... MapReduce, batch, ... GFS, Colossus, ... Even GCE itself: VMs in containers Google launches 4 billion containers per week.

Serverless agility for containerized apps Cloud Run One experience, where you want it One developer experience Fully managed or Your GKE cluster Consistent APIs & tooling Portable with Knative Without vendor lock-in Natively Serverless No servers to manage Focus on writing code Scale up fast Scale down to zero Pay for exact usage Container to production in seconds Just "deploy" Any stateless container Any language, any library URL in seconds

Cloud Run — Container contract ● Stateless ○ Don’t store data in a database ○ Only an in-memory file system ● HTTP payloads ○ Listen on 0.0.0.0 on port $PORT ○ Start an HTTP in < 4 minutes ● Concurrency ○ Up to 80 concurrent requests ● Linux 64 bit binaries ○ x86_64 ABI format

Cloud Run — Pay per use CPU / Memory / Requests 100ms

@glaforge Knative Cloud Run on GKE

@glaforge Serverless operational spectrum Managed by your cloud Container orchestration (k8s) Not serverless for programming or ops Container focused Infra managed by you Hosted FaaS/compute Easiest dev experience Code focused Limited runtime options Managed by your team Serverless anywhere Knative / Cloud Run on GKE On prem or multi-cloud Code or containers Custom hardware (GPU, TPU, IoT, etc) Offline You manage infra Serverless containers Custom languages & runtimes Infra still cloud-managed New! Serverless anywhere Knative / GKE serverless addon On prem or multi-cloud Code or containers Custom hardware (GPU, TPU, IoT, etc) Offline You manage infra

Cloud Run — Managed vs on GKE Cloud Run (fully managed) • Fully serverless • No cluster to manage, minimal ops • Pay for what you use • Limited instance sizes Cloud Run on GKE • Serverless developer experience • Runs in your GKE cluster, K8S ops • Custom machine types (CPU/GPU/Mem)

@glaforge Knative — Serverless building blocks on Kubernetes Kubernetes-based building blocks for serverless workloads Build Serving Events

@glaforge Knative — Partners
