Cloud?
If possible, use Paas!
Use IaaS the smart wayDon’t be stupid when using IaaS!
IaaS ‘pro’ tips
use autoscaling
use spot/preemptible instances
use whole cloud ecosystem - don’t use it as VPS, please…
think about deployment security - when using AWS use Instance Profiles, please…, when using GCP familiar yourself with oAuth
set billing alerts ;)
remember Uncle Bob’s Winston Churchill’s qoute: “Where there is great power there is great responsibility”
deployment scripts… terraform?
Sometimes bare metal is better!
