4 75% of application development supporting digital business will be built not bought by 2020 Source: Gartner

5 2 Near-free
 computing costs Mobile devices
 and connectivity Ubiquity of
 embedded sensors Global scale
 of operations KEY TRENDS The cost and ubiquity of computing enables cloud native software companies to reshape the world

WE BELIEVE Competitive advantage or innovative cost reduction can only come from custom built software, not packaged applications.

An idea in the morning, is running in production by evening https://www.wealthfront.com/engineering Can you release new features to your customers every week?

 Run it on the cloud for me
 I do not care how”

16 “How much value do 
 you get from managing operating systems”

17 Focus On First Principles • Everything run as a service before it’s shipped as software • Zero human intervention in individual machines through lifecycle; immutable platform infrastructure • Service automation’s goal is to ship holistic cloud services not ad-hoc automation simplicity • Multi-cloud primitives vs. AWS only features etc

Spring Boot Adoption

21 First Principles • Velocity and autonomy of delivery for large teams in enterprise environments
 • Enterprise safety/security with startup cycle time (simple repeatable deploys) • Optimized for Cloud Native applications 
 • “Velocity on the JVM is the Killer App”

+ Spring Boot From 0 to app in < 5 min Enterprise Java with dynamic language productivity Spring Cloud Designed for fragile infrastructure in partnership with Netflix Java Microservice Framework 100% Spring Boot enabled

Spring Cloud

25 • Runtimes and their client libraries for: – Service Discovery – Configuration Management – Circuit Breakers – Intelligent Client Side Routing – Reverse Proxies – ….and much more • Security (encrypt, SSO, roles) • Connectors for CF, Heroku, AWS Spring Cloud application coordination patterns

26 Service Registration / Discovery

27 • Fully integrated to Cloud Foundry Service – dramatically lower operational complexity
 • Enterprise Security – OAUTH2, HTTPS, CF UAA integration, RBAC
 • Simple provisioning and setup – Lower operational costs and time to provision Spring Cloud Services for PCF NetflixOSS-as-a-service in Pivotal Cloud Foundry

28

29 PCF Metrix • Fast feedback loop • Live stream and 24 hours of data • Works without an embedded agent • Metrics include: – HTTP requests and errors – Avg. response latency – CPU, memory and disk – App events like start, stop, scale, update, and crash
