3. How do we architect for Continuous Delivery?
4. The ability to get changes—features, configuration changes, bug fixes and experiments—into production, or into the hands of users, safely and quickly in a sustainable way Jez Humble - Author of ‘Continuous Delivery’
5. State of DevOps Report 2018
6. The two rules Everyone is checking into trunk daily (at least) Software (trunk) is always deployable
7. Foundations Configuration management Continuous integration (CI) Continuous testing
9. Portability Testability Scalability Security Maintainability Usability Availability Personalizability Responsiveness Upgradability Extensibility Flexibility Deployability
10. Deployability Testability
11. Operations at web scale is the ability to consistently create and deploy reliable software to an unreliable platform that scales horizontally Jesse Robbins - former ‘Master of Disaster’ @ Amazon

14. Decomposition of systems
15. Component / service Part of your system that could be swapped out for another implementation Martin Fowler
16. Component / service Make system more maintainable (better encapsulation, lower coupling) Make system easier to build and test Enable collaboration (one team per service)
17. Bind components at Run Time (Microservice) Independent deployment Use cluster infrastructure Kubernetes, Service Fabric, … Don’t break downstream API versioning Blue / Green deployment Cater for failure in downstream system Circuit breaker Retry pattern Monitoring is complex
18. Bind components at Build Time (Monolith) Google, Facebook, Etsy Continuous Integration at scale
19. Architecture evolves
20. Monolith First Martin Fowler
21. Microservice Monolith Productivity Complexity
23. Strangler application
