The document discusses the evolution of cloud computing and serverless architecture, emphasizing how cloud functions allow developers to build applications without managing servers. It contrasts traditional infrastructure models with serverless environments, highlighting their cost-effectiveness and flexibility through event-driven functions. Additionally, the text illustrates practical use cases of cloud functions for scalable applications, minimizing development friction and optimizing resource use.

5. No Servers? Really??

8. Traditional Infrastructure

9. Infrastructure evolution over the years

10. Though servers exist,
developers don't have to think
about them

11. Cloud Functions
A serverless environment to build and connect
cloud services with code

12. Cloud Functions

13. Cloud Functions is event-driven

14. FaaS fundamentally
changes financial
incentives for
deployment
architectures

15. How to design Serverless
Entire applications architected as functions &
events that use other services w/serverless
qualities

16. Microservices over monoliths
Cloud Functions lets you build and deploy services
at the level of a single function, not at the level of
entire applications, containers, or VMs.

17. Cost - IaaS vs Serverless

18. Old-School development model
When a user uploads a photo... … crop it for the profile page

19. Old-School development model
Setup a high-end server to serve a single route
Upload photo Crop photo

20. Not too bad right?

21. Old-School development model
So now I want to…
● Crop the image and store the profile
● Resize the same image for my user gallery

22. Let’s add more logic to our
route!

23. Old-School development model
Upload photo
Crop photo
Resize image
Store in Cloud

And we’re done!

25. Old-School development model
So now I want to…
● Crop the image and store the profile
● Resize the same image for my user gallery
● Index the profile image for search

26. Old-School development model
Upload photo

Add even more logic to the route!

28. Using the Event-driven model

29. In Cloud Functions
Do more with less

30. Simple

31. Efficient

32. Extensible, but how?
Add more logic to the server route,
right?

33. Ditch the server!
For every new feature, the route
has to be delicately modified

34. Extensible, with Event-driven model

35. Extensible
So now I want to…
● Crop the image and store the profile
● Resize the same image for my user gallery
● Index the profile image for search
● Analyze the image content and index the attributes
for even better searches

36. With an Event-driven model

37. Demo Time!

39. Use cases

41. Don’t believe the FUD

42. Value of frictionless innovation
Software engineers at leading startups and
enterprises are deploying serverless architectures
to convert innovative product ideas into
consumable value — with minimal friction and
negligible cost.
