Transcript

1. James Thomas, IBM Building Cloud Native Applications
2. Software is eating the world http://blog.softwareinsider.org/2014/02/18/research-summary-sneak-peaks-from-constellations-futurist-framework-and-2014-outlook-on-digital-disruption/
4. What do they have in common? “Speed of innovation”
5. Cloud Computing
7. How can we do the same?
8. “The Cloud” is not just a bigger server…

13. “The Cloud” is not just a bigger server… … requires fundamental re-architecture of applications
14. 1. Twelve-Factor App 2. Microservices 3. API-Based Collaboration 4. Self-service Agile Infrastructure 5. Anti-Fragility
15. The Twelve Factors - http://12factor.net/ I. Codebase One codebase tracked in revision control, many deploys
 II. Dependencies Explicitly declare and isolate dependencies
 III. Config Store config in the environment IV. Backing Services Treat backing services as attached resources
 V. Build, release, run Strictly separate build and run stages
 VI. Processes Execute the app as one or more stateless processes VII. Port binding Export services via port binding VIII. Concurrency Scale out via the process model IX. Disposability Maximize robustness with fast startup and graceful shutdown X. Dev/prod parity Keep development, staging, and production as similar as possible XI. Logs Treat logs as event streams XII. Admin processes Run admin/management tasks as one-off processes
16. …with API-based collaboration

17. Self-Service Agile Infrastructure
19. Sounds like an enormous amount of work?
20. There’s a shortcut…
22. 22 ~ Minutes Platform as a Service Customer Managed Service Provider Managed Benefits Setup environments and deploy apps very quickly. Infrastructure and platform managed by SP. Time Commitment Minutes to setup and deploy. Focus on your apps and their data. ~ Weeks Code Data Runtime Middleware OS Virtualization Servers Storage Networking Core IT ~ Days Code Data Runtime Middleware OS Virtualization Servers Storage Networking Code Data Runtime Middleware OS Virtualization Servers Storage Networking Time to initial deployment Infrastructure as a Service Core IT
