‘architecture’ an ‘ingredient’ on each of our teams.”

Coping with complexity remains a challenge
• Cascading failures
• Circuit breaker
• Feedback loops
• Monitoring changes
• Cattle v pets
• Queue depth, dependencies
• Self-healing infrastructure
• Don’t NIH the platform

How? DevOps
What? Microservices
Why? Survival
