SpringOne Platform 2016 Speaker: Doug Sherman; Principal Engineer, DreamWorks DreamWorks Animation is a company that has historically thrived on taking advantage of cutting edge technologies and has more currently set its sights on further utilizing Microservices and the Cloud as part of its movie making process. This session will review the efforts that took place in both the initial phases which incorporated targeted parts of the Spring Framework, as well as more current efforts that leveraged Spring projects such as Spring Boot, Spring Data and Spring Cloud. Highlighted throughout the talk will be examples demonstrating the pros and cons of various approaches taken, including the social engineering aspects of changing a movie making culture to fully embrace what it means to adopt a Microservices platform.

19. DREAMWORKS ANIMATION
is a DIGITAL MANUFACTURER
Creating high value in a high-end
digital product that is distributed and
consumed worldwide

20. • 75,000,000 CPU hours
• 10,000+ cores
• 200+ terabytes of data
• 500,000,000 files
• 250,000,000,000 pixels
IN JUST ONE FILM…

22. Where did we start?
• One show released every
few years
• Each show typically had
their own pipeline
• C++, Perl scripts (later
Python) were the norm
• There was one lone Java
application with Swing
• Workflows were very
client-heavy

23. How did that go?
• Was hard to monitor
• Where are these things
running?
• Risky to make changes to
monolithic code
• Assuming devs were
still around
• Difficult to scale
• Some software couldn’t
work between sites

24. Where did we go next?
• More Movies perYear == New Architecture
• New Architecture == Adoption Challenges
• SOA & Microservices introduced
• SOAP… then REST
• C++/Python... then Java
• JEE… then Spring

25. Transitions
• SOA felt overwhelming at the start
• SOAP, XML, ESB, BPEL,App Servers
• Java wins for sure… and Spring helped
• Microservices via REST / JSON easier
• Spring leaned on for REST, DBs,Testing
• Spring Messaging… was... interesting

26. Transition for Clients
• Clients provided language specific wrappers
• Pros
• Clients could call upon a familiar API
• Cons
• Clients could call upon a familiar API
• Education and experience helped

27. Ultimately, how did it all go?
• Foreign architecture required “Social Engineering”
• Encouraged client & server developers
• Things improved with new Platform & QA teams
• Microservices scaled to meet multi-show demand
• Optimal databases could be used per service
• Smaller teams + smaller targets = agility

28. What are we doing now?
• Spring Boot
• Convention over configuration
• Where are my beans???!
• “Make Jar, not War” – Josh Long
• JEE App Servers on way out
• Actuator … yes, please!
• But what about “other” services
in other languages?
• http://spring.io has great examples
• Move everything to Spring Boot?

29. What else are we doing now?
• Spring Data
• Simple… maybe too simple?
• Supports many of our DB choices
• Oracle/PostgreSQL
• Cassandra
• MongoDB
• ElasticSearch
• Move everything to Spring Data?!
• Spring Cloud
• Configuration for starters

30. Lessons learned so far?
• Generalists are key to our success
• So many frameworks
• So many databases
• So many containers
• So many languages
• Social Engineering is important
• Take time to share ideas
• Build with your consumers
• But offer opinions
• Keep your vendors honest!

31. Spring specific lessons learned
• Don’t fear change
• Using XML config in Java??!
• Stop using XML config in Java?
• Spring Boot is wonderfully
different
• Don’t settle
• Spring Boot, Spring Data and other
packages may not offer it all
• Leverage the experts when you can
• Do more with less

32. Where are we going next?
• Going Cloud-Native
• Exposing more RESTful APIs
• Embracing the container
• Trying to make CI / CD a reality

33. Questions?
