EVOLVE YOUR ELEPHANTS

3. WHERE WE’VE BEEN Brad Wood

4. APPLICATION ARCHITECTURE
SPAGHETTI CODE (PROCEDURAL)
▸ Quick and dirty
▸ Logic and display mixed together
▸ Monolithic app design
▸ No separation
▸ Difficult to extend/scale

5. APPLICATION ARCHITECTURE
OBJECT ORIENTED CODE (OO) -- WITH MEATBALLS
▸ Logic organized better
▸ Service-oriented
▸ Monolithic app design
▸ Some separation
▸ Difficult to scale

6. APPLICATION ARCHITECTURE
MODEL VIEW CONTROLLER (MVC)
▸ Separates layers of concerns
▸ Helps enforce OO
▸ Specialized team members
▸ Layers are still tightly coupled

7. APPLICATION ARCHITECTURE
N-TIER
▸ Add more layers for organization
▸ Layers are still tightly coupled
▸ Still monolithic!

8. APPLICATION ARCHITECTURE
ONCE YOUR APP GROWS...
▸ Complex real-life apps
▸ Large “surface area”
▸ So...much...code...
▸ No one understands it all
▸ Too big for one plate

9. APPLICATION ARCHITECTURE
MODULARITY ENSUES
▸ Microservices
▸ Break app into logical pieces
▸ Drop-in functionality
▸ Re-usable
▸ Multi-team approach
▸ Easier to distribute

10. ▸ A monolith can only
scale up
▸ Find logical areas to
break up
your app
▸ Smaller pieces can
scale out

16. WHERE WE’RE GOING Jon Clausen

17. YESTERDAY’S PARADIGM

18. …BIGGER HARDWARE!
IF IT DOESN’T PERFORM…

19. …MORE HARDWARE!
IF IT STILL DOESN’T…

20. TECHNOLOGY EVOLVES…

21. A FUNDAMENTAL
CHANGE IN
APPROACH OR
UNDERLYING
ASSUMPTIONS.
PARADIGM SHIFT:

22. From Big Hardware…
…to

23. PLATFORMS AS SERVICES (PAAS)

24. THE NEW PARADIGM: ORCHESTRATION
▸ Less is more
▸ Applications as
collections of
independent parts
▸ Incremental upgrades
and versioning in lieu
of massive release
cycles

25. THE NEW PARADIGM: ORCHESTRATION
▸ Hardware
Independence
▸ Platform
independence
▸ Disposable instances:
scale on-demand,
teardown when
demand decreases

26. AN APPROACH TO DEVELOPING A SINGLE
APPLICATION AS A SUITE OF SMALL SERVICES,
EACH RUNNING IN ITS OWN PROCESS AND
COMMUNICATING WITH LIGHTWEIGHT
MECHANISMS.
Martin Fowler
MICROSERVICES:

27. ▸ Make legacy code updates less
intimidating
▸ Fewer resources required to
maintain fault tolerance
▸ Versionable & maintainable
▸ Short release cycles
▸ Monolithic apps can be evolved
piece by piece
MICROSERVICES:

28. FROM LEGACY CFML APPS
MICROSERVICES

29. STEP 1:
Identify performance
bottlenecks and pain points
in your application

30. STEP 2:
Build, test, and deploy new
microservices to address
and deliver the functionality
of your pain points

31. STEP 3:
Update endpoints in
monolithic app to use new
microservice endpoints

32. STEP 4:
Rinse and repeat, with
additional bottlenecks and
pain points

33. TOOLSET

36. CONTAINERIZATION
▸ Reduces Time-consuming dev-
ops tasks via automation
▸ Allows for hardware and engine
Independence
▸ Health checks and rolling
updates allow for zero-
downtime deployments
▸ Built-in emergency procedures
and configuration settings
provide better application fault
tolerance

37. CONTAINERIZATION
▸ Portable between
platforms, machines, data
centers, and geographic
regions
▸ Built-in security and
isolation
▸ Transients vs Singletons -
spin up more when
needed, tear down when
demand is reduced

38. IN A…

39. INSTEAD OF ONE
BIG THING, DOING
MANY THINGS…
ISOLATE
ALL THE THINGS!

40. …WE DEVELOP
MANY THINGS,
EACH
DOING ONE THING
VERY, VERY WELL.
ISOLATE
ALL THE THINGS!

41. IF WE DO THIS,
ONE
SMALL
PIECE AT A TIME

42. SOMEDAY SOON, THIS

43. EVOLVES INTO TO THIS

44. WE CAN HELP YOU WITH THE TOOLS
