The document discusses GitOps and a new paradigm called cloud native applications. It promotes GitOps as an approach where the entire system, including code, config, monitoring rules and policies are described in a Git repository. This allows the entire system to be destroyed and re-built with no human intervention. It then describes Automium, a solution the author's company built based on GitOps fundamentals to help with cloud transformations.

5. Twenty years’ experience
in datacenter and cloud services
led us to believe that stability,
reliability and performance
are not in the product, but
in the process.

6. Conway’s Law
Organizations which design
systems […] are constrained
to produce designs which are
copies of the communication
structures of these organizations.

7. Siloed functional teams… … lead to siloed application architectures.

11. A microservices architecture
is automated

12. A microservices architecture
is distributed
A monolithic application
puts all its functionality
into a single process…
…and scales by
replicating the monolith
on multiple servers
…and scales by
distributing these
services across servers,
replicating as needed.
A microservices
architecture puts each
element of functionality
into a separate service…

13. Automation + distribution = cloud

14. I said cloud, not virtualization

15. “Cloud Native applications are a combination of existing
and new software development patterns.
The existing patterns are software automation
(infrastructure and systems), API integrations,
and services oriented architectures.
The new cloud native pattern consists of microservices
architecture, containerized services,
and distributed management and orchestration.

16. There’s no benefit in moving
your monolithic app to the
cloud as it is (“lift and shift”)

17. You are given two options:
refactor your app or…

18. … stick to where you are now.

19. But you can also start your personal
journey to a cloud transformation

20. Join the DevOps
movement

21. Look at the Entire System

22. Amplify Feedback Loops

23. Never Stop Experimenting
and Learning

24. Most people would
rather die than think.
Many do.
Bertrand Russel

25. Let the robots
take over: cloud is
for machines talking
to each other

26. From DevOps to GitOps:
versioned CI/CD on top of
declarative infrastructure

27. The entire system including code,
config, monitoring rules and
policies is described in Git

28. The entire system can be destroyed
and re-built with no human
intervention

29. Monitoring and observability
is baked into the beginning

30. Starting from the GitOps
fundamentals we built Automium,
our solution for cloud transformation

33. Automium integrates with
vvv v

34. Why GitOps (and Automium)
are the future of operations

35. You can start where you are, with
no other platform or services to
integrate in your workflow

36. Any developer can use Git,
so any developer can join
your team and ship new apps
or make changes easily

37. The entire system is provider
neutral, so you can deploy
wherever you want: freedom
is our lock-in
