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!

Agile?
