Keep Your Hands OFF !
Going "Serverless" with GCP... and G Suite
What is "Serverless"
"Serverless" is NOT a replacement for DevOps (culture)
Basic DevOps culture is needed
"Serverless" are more than functions
"Serverless" is NOT
one size fit all
Find the tool that best suit your needs!
Why "Serverless"
Once upon a time...
There were sysadmins!
"You build it, you run it" - Werner Vogels, CTO, Amazon
DevOps - infra, tools and culture
Developers - develop and deploy
Not suitable for small to medium sized orgs ?
DevOps - culture
Cloud Provider - infra and tools
Developers - develop and deploy
"Serverless" with GCP ?
- Compute Engine
- Kubernetes Engine
- App Engine (Standard)
- App Engine (Flexible)
- Cloud Functions
- App Maker (from G Suite)
- Cloud Run (in beta)
Infrastructure as a Service (IaaS)
Google Compute Engine (GCE)
- Virtual Machines
Google Kubernetes Engine (GKE)
- Cluster of nodes / VMs (orchestration)
Serverless 🤔 ?
Why IaaS?
- For larger organisations, economies of scale
Function as a Service (FaaS)
Cloud Functions
- Function triggered by events (e.g. HTTP)
- Limited Runtimes but lightweight
Serverless 😊 !
Why FaaS?
- Solving singular problems that are decoupled from other applications
- May not be for frontend development
Software as a Service (SaaS)
App Maker
- GUI to make applications
Serverless 🤢
Platform as a Service (PaaS)
Google App Engine (GAE)
- Standard vs Flexible
Standard VS Flexible
- Flexible - No restrictions on runtimes
- Standard - deployed in sandbox - faster
Serverless 😇
Why PaaS?
- Balance between all tools
- Good for frontend development
Cloud Run
The new kid around the block (*beta)
Cloud Run
- Runs on a Dockerfile schematic
- Managed or run alongside GKE
Cloud Run vs
App Engine Flexible
Let's make a CICD pipeline with "Serverless" infrastructure !
