While there are many Cloud design patterns for infrastructure, there are also many Cloud design patterns for developers. Come and learn how you can take your software design patterns and apply them to the next generation of cloud applications, or simply modernise your existing software architectures.

Combine into reusable parts
General repeatable solutions to
commonly occurring problems

Design Patterns:
Elements of Reusable Object-­
Oriented Software
Erich Gamma, Richard
Helm, Ralph Johnson
and John Vlissides

11. What Did Software Design Patterns Give Us?
Well Documented
Understood by software
architects and developers
Reduce Risk
Tried and Test solutions to
common problems
Reduce Development Time
Familiarity with patterns
reduces development time
Common Language
Collaborate and Share
Flexible
Can be tailored to specific
problem
Reduce Complexity
Solution becomes easier
to comprehend

12. Why Do Your Customers Care?
• Reduced Cost
• Dramatically increase Speed and Agility
• Increase Innovation
• Stop spending money on Undifferentiated Heavy Lifting

13. In the cloud, if infrastructure really is code,
where are the patterns?

14. “I think frugality drives innovation, just
like other constraints do. One of the
only ways to get out of a tight box is to
invent your way out” – Jeff Bezos, CEO Amazon

30. AWS Lambda
A compute service where you
don’t have to think about:
• Servers
• Being over/under capacity
• Deployments
• Scaling and fault tolerance
• OS or language updates
• Metrics and logging
…but where you can easily
• Bring your own code…
even native libraries
• Run code in parallel
• Create backends, event
handlers, and data
processing systems
• Never pay for idle!
