- 3. @eljuanchosf The world is changing... Since the year 2000, 56% of the Fortune 500 companies are no longer on the list. fast
- 7. @eljuanchosf “Software is eating the world” Marc Andeerssen - cofounder, Netscape
- 9. @eljuanchosf Adaptability & Agility A system should be able to respond quickly to change. What brings change: Humans using that system Business model Hardware Software “The measure of intelligence is the ability to change.” Albert Einstein
- 10. @eljuanchosf Resilience A system should be able to recover from failure. What can go wrong? Software instability Physical failure Attacks Natural disaster “Our greatest glory is not in never falling but in rising every time we fall.” Confucius
- 11. @eljuanchosf Cooperation A system should be able work together with other systems. Why? Specialization leads to either cooperation or isolation Complex systems are made of simpler systems working together “Coming together is a beginning; keeping together is progress; working together is success.” Henry Ford
- 13. @eljuanchosf An ever-changing group of methodologies and tools that allows software systems to be adaptable, agile, resilient and cooperative.
- 14. @eljuanchosf The Cloud Native toolbox Automation Infrastructure as code Platform as a Service Containerization 12 factor apps Continuous Integration & Delivery Source control Multi Data Center
- 15. @eljuanchosf Infrastructure as code A way to manage and provision infrastructure from the ground up with a high level or descriptive language. Terraform Puppet Chef Ansible BOSH
- 16. @eljuanchosf Platform as a Service A way to develop, run and manage applications without going into the complexities of managing the underlying infrastructure. Heroku Amazon Elastic Beanstalk Cloud Foundry (IBM Bluemix, Pivotal Web Services, GE Predix) Google App Engine OpenShift
- 17. @eljuanchosf Containerization A technique of encapsulating applications in containers with its own operating environment, abstracting them from the operating system. LXC Docker Rocket Warden/Garden (Cloud Foundry)
- 18. @eljuanchosf 12 factor apps A methodology of writing applications that allows system and software architects, and developers, to create software that can run in the cloud seamlessly. 1. Codebase in revision 2. Declare dependencies 3. Config in environment 4. Backing services = attached resources 5. Separate build and run stages 7. Export services via port binding 8. Scale out via process model 9. Fast startup, graceful shutdown 10. Environments parity 11. Logs = events streams 12. Admin processes as tasks
