Build it well. Secure it properly. Automate everything possible.

I believe security should be considered during architecture and development — not added as an afterthought.

I also strongly prefer tools and systems that are:

• Simple to deploy
• Easy to maintain
• Observable
• Secure by design
• Automatable
• Self-hostable when practical
