Companies need to build better software faster to compete. But existing monolithic applications, legacy platforms, and lengthy operational deployment cycles are holding innovation back. Microservices are becoming the cloud architecture of choice because they offer the ability to loosely couple applications into discrete services that can be surgically changed without requiring disruptive overhauls. This approach enables the responsiveness and rapid change needed by the business. Enterprise PaaS is a critical foundation to simplify the operations, governance, and health management of these new architectures. Together with a DevOps culture, microservices and PaaS are the engine that drives innovation at speed.

1. DevOps, !
microservices,!
& the new !
composable enterprise

2. What in the world !
is DevOps, anyhow?

3. Agile, truly tip to tail
Business to customer

4. Tear down all the silos

5. “Infrastructure as code”

6. #monitoringsucks/#monitoringlove

7. Organizations with high performing DevOps
organizations were 2x more likely to exceed
profitability, market share and productivity
goals…!
!!!!
…and had 50% higher market
capitalization growth over 3 years…

10. CI/CD & the !
changing roles !
of Devs and Ops

11. Test your infrastructure like your code

12. The composable enterprise!
and the Yegge memo

13. Containerization

14. Stack Overflow container traction

15. Microservices (not monoliths)
Separation of (business) concerns into services
accessed via REST APIs
Resilient to failure, easily reusable, etc

16. Platform as a Service (PaaS)
Has its time finally arrived?

17. The view from 40,000 feet

18. Minimizing risk, Maximizing agility
l Architecture: Microservices, monitoring
l Code: Continuous integration, feature flags
l Servers: Continuous delivery, infrastructure as code
l Services: Rolling updates, resilient engineering
l Product: Continuous deployment, restricted audience

• Config via Environment
• Attached Backing Services
• Separate Build/Release/Run
• Stateless Processes
• Export Services via Port

24. New Architectural Constraints
• Pivotal CF optimizes for 12 Factor Linux applications
• Microservices: a radical departure from traditional
monolithic applications
• In both cases, the enterprise is
forced to “think different.”
