This document discusses DevOps culture and practices, including collaboration, communication, holistic software development approaches, continuous integration/deployment, open source, microservices, containers, infrastructure as a service best practices, and the relationship between DevOps and security. It suggests that cloud and DevOps can promote peace of mind depending on how they are implemented, with a focus on collaboration, responsibility, and using technologies and practices intelligently.

Don’t be stupid when using IaaS!

27. 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
