5 Essential Cloud Architecture Principles

Building robust cloud applications requires following proven architectural principles. Here are the five most important ones I’ve learned from years of consulting experience.

1. Design for Failure

Assume everything will fail and build resilience into your systems from day one.

2. Embrace Automation

Manual processes don’t scale. Automate everything you can.

3. Monitor Everything

You can’t improve what you don’t measure.

4. Keep It Simple

Complexity is the enemy of reliability.
